INTRODUCTION
More than 17,000 miles of highway of all types were completed during the year, exceeding the work of the previous year by about 1,800 miles and sustaining the high rate of progress initiated in the fiscal year 1934. In the program of grade-crossing elimination and

protection 382 crossings were eliminated, 86 obsolete elimination structures were reconstructed, and 438 crossings were protected by signals and other devices.
Outstanding features of the year’s work were the large amount of work done in widening, straightening, and otherwise modernizing important main highways, the excellent progress made in eliminating hazards at railroad grade crossings, and the completion of nearly 3,000 miles of secondary roads in the program begun in the preceding year.
In the work done in cooperation with the States and under the immediate supervision of the State highway departments 9,786 miles were completed on rural portions of the Federal-aid system, 2,971 miles on the secondary or farm-to-market systems, and 725 miles were improved in municipalities. Improvements in federally controlled areas, reconstruction of flood-damaged roads, and construction of roads with funds allotted by other Federal agencies aggregated 3,678 miles.
The Bureau of Public Roads and all of its functions were transferred from the Department of Agriculture to the newly created Federal Works Agency, and its name was changed to the Public Roads Administration by Reorganization Plan No. 1 prepared by the President, pursuant to the provisions of the Reorganization Act of 1939. The plan was transmitted to Congress on April 25, 1939, and was made effective on July 1, 1939, by a Joint Resolution of Congress adopted June 7, 1939.
The reorganization plan transfers all functions of the Secretary of Agriculture relating to highway improvement with Federal aid to the Federal Works Administrator. The title of the Chief of the Bureau of Public Roads is changed to Commissioner of Public Roads.
The Federal Works Agency is headed by the Federal Works Administrator and is composed of the Public Roads Administration, the Public Buildings Administration, the United States Housing Authority, the Public Works Administration, and the Work Projects Administration.
FUTURE HIGHWAY NEEDS BECOMING CLEARLY EVIDENT
During the year the Bureau completed the first comprehensive study ever made of the national highway situation, taking into account conditions on city streets, main rural highways, and on secondary or farm-to-market roads. The study was possible because of the wealth of data that have become available through the highwayplanning surveys in cooperation with 46 State liighway departments. These data show accurately and in great detail the volume, character, and range of traffic, the condition of existing highways, and the need for new facilities.
As a result of exhaustive studies of these data the Bureau prepared a master plan for future highway improvement which was included in the report entitled, “Toll Roads and Free Roads.” This report was submitted to the President, who on April 27, 1939, forwarded it to Congress with the recommendation that it be considered as a basis for needed action to solve our highway problems.
The report recommends:
1.	The construction of a special tentatively defined system of direct interregional highways, with all necessary connections through and aiound cities,
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE. 19 3 9	3
designed to meet the requirements of the national defense in time of war and the needs of a growing peacetime traffic of longer range.
2.	The modernization of the Federal-aid highway system.
3.	The elimination of hazards at railroad grade crossings.
4.	An improvement of secondary and feeder roads, properly integrated with land-use programs.
5.	The creation of a Federal Land Authority empowered to acquire, hold, sell, and lease lands needed for public purposes and to acquire and sell excess lands for the purpose of recoupment.
A system of direct interregional highways, with necessary connections through and around cities, is needed to meet the growing peacetime traffic of longer range and the requirements of national defense in time of war. Studies of the present flow of traffic on main highways indicate that such an interregional system should comprise not more than 30,000 miles. No attempt has been made as yet to fix the exact location of the proposed system. Existing highways could be modernized to form a large part of the system, but some new highways would be needed to provide directness of travel. A system of the scope suggested would represent less than 1 percent of the total mileage of rural roads, but the Bureau estimates that it would serve at least 12.5 percent of the travel outside of cities.
The more complete information on the character of traffic in and near cities that has become available shows that existing facilities are seriously inadequate. The situation is becoming more aggravated by increases in traffic, and only the provision of major improvements at a large cost will provide a solution. Such improvements would be a necessary part of an interregional system.
It is found that as much as 90 percent of the traffic on main highways near the entrances to large cities is bound to or from points in cities themselves and cannot be bypassed around them. The studies reveal also that a large part of the traffic is destined to or bound from points in the very heart of the city or points most conveniently reached by going through the center of the city.
There is need for express highways cut directly into and through the center of the big cities. These are needed not only for service of the through traffic delivered by the main rural highways but also for the daily in-and-out movement of local traffic between the downtown section and suburbs centering about the main highways at the periphery of the city.
By preference such express highways should be constructed as attractively landscaped depressed thoroughfares passing under all cross streets.
Bypasses—the remedy usually proposed for the relief of congestion on through streets in cities—are only a partial and, by themselves, a not very effective remedy. They are recommended around the smaller towns, and a new type of belt-line distribution road around cities is proposed. For maximum effectiveness, both the bypass and distribution highways must be free from cross traffic, parked vehicles, and developments immediately adjacent, to preserve their initial advantage against the encroaching growth of the urban community, which otherwise soon converts them into ordinary local streets.
Outside of city limits on the main highways there is need for modernization of the existing roads to ease curvature, reduce gradients, and extend sight distance in order more safely to serve fast-moving traffic. Near the cities, also, a steadily increasing mileage of four-lane divided highways is believed to be required.

BUREAU OF PUBLIC ROADS
Such improvements are required on most of the mileage of the Federal-aid and State highway systems, especially those parts built before the recent considerable increase in the travel speed of motor vehicles. For the most part they involve only local changes in the existing roads. By such changes the bulk of the highway traffic that moves between adjacent cities will be amply served. Many improvements of this kind were made in the Federal-aid work of the past year.
No Federal undertaking has met with stronger public support than has the program of elimination of hazards at railroad grade crossings. This work should be continued.
The plan proposed for future highway improvement includes improvement of a carefully selected mileage of secondary and feeder roads to give direct service to a larger number of rural dwellers. The selection would be made from among the 2,618,000 miles of roads outside of State and Federal-aid systems. Constituting about 83 percent of the country’s total road and street mileage, these lesser roads serve at present only about 13 percent of the total vehicle mileage of traffic. Located on them, however, are the homes and working places of about 75 percent of the rural population. The purpose of the improvement of an additional mileage of these roads, therefore, is that of affording better access to rural property rather than the service of a large increment of traffic. The choice of the roads to be improved should be made in close comformity with a program looking to the promotion of economically and socially beneficial land use.
Creation of a Federal Land Authority, empowered to acquire and lease land for public purposes, and to acquire and sell excess land for the purpose of recoupment is only one of several steps that need to be taken toward a solution of highway right-of-way problems.
Engineers trying to create a system of modern highways are everywhere delayed, and the public is forced to pay high prices for needed land, because of laws and a procedure adopted in the days of horse-drawn vehicles. In some States construction may be delayed for months by numerous legal steps, the width finally acquired is often less than that needed for a modern highway, and practically always the steps necessary to acquire rights-of-way are delayed until conditions are unfavorable to the acquirement except at a high price. A marked improvement can be produced by study and revision of State laws.
This step alone will not solve the most serious part of the problem. Along main highways in need of widening and relocation adjacent land steadily increases in value. Buildings are erected and subdivisions are developed, so that the number of owners who must be dealt with constantly increases. As a result of their planning work highway officials can determine with considerable accuracy the land that will be needed in the next 20 years to provide for an adequate highway system.
It is proposed that the Federal Government supply the means of acquiring lands selected by State officials and hold such land subject to lease by the State over a period of 50 years on terms that would in that period amortize the initial cost.
There is no action more necessary than providing the means of obtaining rights-of-way before they increase further in price. In

and near the cities the cost of land for the needed improvements may often exceed the cost of construction. Continuation of the present policy will result in such high costs for land that funds may not be found to pay both land and construction costs. We are now paying dearly because in the past funds could be found only for immediate right-of-way needs. The mistake should not be repeated.
Experience in England and Canada in the taking of land in excess of that needed for highway improvement and in later reselling.at a profit indicates that such a policy, under proper constitutional authority, might well be applied in this country. The fact that a rise in land value accompanies major highway improvement is well known, and it seems reasonable that the public should derive some benefit from the value it creates.
BUREAU RECOMMENDS AGAINST A SYSTEM OF TOLL HIGHWAYS
The report to Congress containing the above recommendations was made in accordance with the act of June 8, 1938, which directed the Chief of the Bureau of Public Roads to investigate and report his findings—
with respect to the feasibility of building and cost of superhighways not exceeding three in number, running in a general direction from the eastern to the western portion of the United States and not exceeding three in number, running in a general direction from the northern to the southern portion of the United States, including the feasibility of a toll system on such roads.
The building of such a system was found to be entirely feasible from a physical standpoint, but it was also found that the system would not come within 50 percent of self-liquidation if operated as a toll facility and would not meet the most urgent highway needs of the Nation.
In studying the feasibility of a toll system, the Bureau selected six routes, located in accordance with the terms of the act and aggregating 14,336 miles. Detailed studies show that the cost of constructing this system for fast-moving traffic without crossmg other highways or railroads at grade would be about $2,899,800,000, which is at the average rate of $202,270 per mile.
The average estimated annual expenditure for the period 1945-60, required for financing the construction, maintaining the property, and operating the facility would be $184,054,000, which is at the average rate of $12,840 per mile per year.
Estimates of the potential traffic on the proposed toll system were based on actual traffic counts on the main highways of the country and studies of the character of highway travel. A number of facts led to the conclusion that only a small portion of present traffic could be attracted to the toll system. Long-distance travel constitutes only a small fraction of the total travel. Counts made on east-west highways at stations established on a line extending from Canada to Mexico showed only 300 passenger veliicles crossmg the line daily in transcontinental travel. The system could be expected to serve adequately only that portion of the traffic having origin and destination close to one of the six routes. Access to the highways would have to be controlled both for collection of tolls and to prevent interference with flow of traffic by entering vehicles. Vehicles traveling distances less than the spacing of access points would not use the toll roads.

BUREAU OF PUBLIC ROADS
It is estimated that the utilization of the system would average during the period 1945-60, 12,450,000 vehicle-miles per day. Assuming toll charges of 1 cent per vehicle-mile for passenger vehicles and an average of 3.5 cents for trucks and busses, this travel would produce an average annual revenue of $72,140,000. This is considerably less than the $184,054,000 estimated average, annual cost and leads the Bureau to conclude that the system studied could not be supported by toll collections.
The portion of the proposed system estimated to be most nearly self-supporting is the 172 miles from a point near Philadelphia, Pa., to a point near New Haven, Conn. With the increase in traffic expected by 1960, this portion of the system would earn slightly more than the estimated cost for that year.
The report states:
If, as an actual test of the feasibility of a limited mileage of toll roads, it is the desire of the Congress to make provision for the construction of a section of highway of substantial length upon which there is a reasonable prospect of the recovery of the costs through tolls, it is recommended that such provision be made applicable to a section of highway, properly located, and extending from an appropriate point near Washington, D. C., to an appropriate point near Boston, Mass.
HIGHWAY SAFETY
The Bureau has consistently sought to reduce the number of deaths and accidents on highways by several courses of action in the belief that only the combined effort of many agencies in several directions can produce the desired results. It is felt that the past year has been one of real accomplishment in this field, but the progress has not been such that the situation can be viewed with complete satisfaction. No one can say how many lives have been saved by highway-railroad grade separations, road straightening and widening, divided highways, and road signs and road marking to direct traffic"in proper channels Such work has had special prominence in the State and Federal programs, and has undoubtedly contributed to the more favorable trend m accident statistics.
There is still a great lack of uniformity in essential features of State motor-vehicle and highway laws despite the availability of the vehicle code recommended by the National Conference on Street and Highway Safety. This code has been available for a number of years, but there are still many States with inadequate inspection of motor vehicles and with only a perfunctory examination before issuing a driver’s license. Disciplining and control of delinquent drivers continues to be strikingly deficient in many instances.
It has been definitely determined that a relatively small group of accident-prone drivers experience a relatively large number of accidents. The danger from these drivers can be removed only through an efficient system of accident reporting, the keeping of accident records, and laws making the revocation of licenses mandatory for flagrant violations of traffic regulations.
. Steps toward improvement of these conditions have been disappoint-mgly slow. Each year a few States make improvements in their traffic laws, provide motor-vehicle inspection stations, make small additions to highway patrol forces, or make provision for accident reporting and the keeping of records. But throughout the country there is still a serious lack of uniformity in traffic laws and inadequate
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 3 9	7
enforcement machinery. Since there is no general sentiment against the more important safety proposals that have been made, the situation can be accounted for only by public and legislative inertia. Increased efforts should be made to bring all States to a high and uniform standard in motor-vehicle regulation and in the enforcement of the regulations.
PROGRESS MADE IN PROPORTIONING THE PHYSICAL DIMENSIONS OF HIGHWAYS
The Bureau is cooperating with a committee of the American Association of State Highway Officials in the development of design standards for the promotion of maximum safety of traffic and utility of highways. Research has been conducted and special studies made to aid the committee in establishing design standards. A policy on classifying highways recommended by the committee has been accepted by the association. Policies as to sight distance and the dimensions of modern road cross sections will soon be submitted to the association for consideration. The committee is being assisted in developing standards for the physical lay-out at highway intersections, and the marking of pavements and erection of signs to indicate “no-passing zones” on two-lane and three-lane highways.
For some years the Bureau has recommended that transition curves be inserted at each end of highway curves to avoid an abrupt change from a straight line to a curving path of travel. The recommendation has not always been accepted because of the additional calculations and field work required. To overcome this objection an easier method of making the calculations with the aid of special tables has been developed and made available in the book Transition Curves for Highways. The method simplifies both the calculations and the field work.
ROADSIDE IMPROVEMENT
Roadside improvement had its beginning in a small way many years ago but it received only slight impetus until the initiation of the emergency program of highway improvement in 1933. Since that time it lias been mandatory that roadside improvement work be included in Federal-aid programs.
Six years of experience with roadside improvement have demonstrated that in building a properly conceived highway the road surface and the roadside cannot be treated separately but must be regarded as a single problem. Consideration of the roadside and the recreational use of highways are responsible for several trends that are becoming increasingly evident. Wider rights-of-way are being obtained; deep ditches have disappeared; wider shoulders are being used; slopes are flatter, more rounded, and planted to grass; footpaths are being built; and picnic areas and parking space at scenic views are now included in highway plans.
Increased attention is being given to roadside regulation and border control. Easements are being obtained to permit improvements beyond the limits of restricted rights-of-way. Rural zoning regulations are being adopted. Many of these specify the distance which buildings and billboards shall be set back from the highway.

NEW LEGISLATION INSURES FUNDS FOR HIGHWAY PLANNING WORK
At the close of the fiscal year Congress was considering a proposal to require the use of not to exceed 1% percent of the regular Federal-aid funds apportioned to each State for highways and for elimination of hazards at railroad grade crossings, in making surveys, plans, engineering investigations, and economic investigations of projects for future construction, either on the Federal-aid highway system and its extensions, or on secondary or feeder roads, or grade-crossing eliminations. The States would not be required to match Federal funds so used. The proposed legislation was enacted July 19, 1939.
This new authority will greatly facilitate the financing of future high way-planning-survey work in all States. Regulations requiring a use of funds in sufficient amount to obtain information required in planning Federal-aid work are being prepared.
DIVERSION OF HIGHWAY FUNDS
During the last decade there has been a very decided tendency on the part of legislative bodies to divert the proceeds of the special taxes on motor-vehicle owners and operators to purposes other than highways, particularly to relief purposes. Congress took cognizance of this fact by declaring in section 12 of the Hayden-Cartwright Act of June 18, 1934, that it is unfair and unjust to tax motor-vehicle transportation unless the proceeds of such taxation are applied to the construction, improvement, or maintenance of highways. The act provides that any State that applies to highway purposes a lesser amount ol motor-vehicle fees and gasoline taxes than was provided by law on June 18, 1934, shall be penalized not more than onc-third of the I ederal-aid apportionments to which it would otherwise be entitled.
A continuous study of the State laws pertaining to disposition of the proceeds of the special taxes on motor-vehicle owners and operators and of their administration has been necessary in order to give reasonable effect to this legislation. Committees and members of State legislative assemblies, State highway officials, and citizens’ organizations submit numerous inquiries each time that such assemblies are in session as to whether certain proposed legislation will constitute a diversion of the proceeds of the motor-user taxes. The requirement this section is believed to have had a wholesome and restraining effect, and undoubtedly has prevented passage of many acts designed to divert highway funds that otherwise would have been enacted.
Since the Federal provision to discourage diversion became effective, a reduction has been made in Federal-aid apportionments to two States. On August 7, 1937, $250,000 was withheld from the apportionment to New Jersey for the fiscal year 1937, and on June 2, 1938, $472 862 was withheld from the apportionment to Massachusetts for the fiscal year 1938. Apparent acts of diversion in other States are under consideration at the present time.
USE OF FEDERAL AID IN FREEING TOLL BRIDGES ON THE FEDER A.L-AID SYSTEM
An act of August 14, 1937, authorized the use of Federal-aid funds apportioned to any State in freeing toll bridges on the Federal-aid system. It permitted payment to the State of 50 percent of the
ANNUAL REPORTS OF THE DEPARTAIENT OF AGRICULTURE, 19 3 9	9
construction cost or reasonable value (whichever might be least) of bridges made free from tolls prior to July 1, 1939. The act also required that funds so paid should be used in matching unobligated Federal-aid funds available to the State. In effect this legislation permitted the Federal Government to pay an increased part or all of the cost of certain Federal-aid projects thus making available for the freeing of toll bridges the State funds that would otherwise be required for matching the Federal funds.
Alabama is the only State that has made use of this legislation. In the past two years $2,025,267 was paid to the State in connection with the freeing of 10 bridges and the payments were applied in lieu of State funds on regular Federal-aid projects.
An act of July 19, 1939, has extended the use of this plan of freeing toll bridges to July 1, 1941.
SOURCES OF FUNDS USED DURING THE YEAR
Tbe work of the year was supported mainly by regular Federal-aid funds. The apportionment for the fiscal year was $125,000,000 for improvement of the Federal-aid system, $25,000,000 for secondary or farm-to-market roads, and $50,000,000 for elimination of hazards at highway-railroad grade crossings. Equal amounts had been provided for the preceding fiscal year, and portions of these funds remained available at the beginning of the past year.
Emergency funds for highway improvement were practically exhausted in the preceding year; and, while a few projects were carried over into the past year and completed, the volume of such.work was not important. However, the work of grade-crossing elimination, supported by remaining portions of the $200,000,000 authorized by the Emergency Relief Appropriation Act of 1935, continued into the past year in considerable amount.
On December 29, 1938, the $135,000,000 authorized for the fiscal year 1940 was apportioned to the States after first deducting $3,375,000 for administrative expenses of the Bureau as required by law. The apportionment is shown in table 1.

EMPLOYMENT ON ROAD WORK
Employment on all highway work with Federal funds administered by the Bureau amounted to 1,121,007 man-months, a decrease of 11 percent as compared with the preceding year. This was expected since appreciable amounts of emergency funds had remained available at the beginning of the preceding fiscal year and had been expended largely in the first half of that year. A comparison of employment by corresponding months of the 2 years shows that there was a decrease of more than 36,000 men in both July and August, and 20,394 fewer men were employed in September. By December there was a difference of only 3,097 men, and the difference was small in the remaining months of the year. Table 2 shows the employment on Federal and State work by months in the fiscal years 1932-39.

Table 3 shows the employment on the various classes of work during the past year. Comparison with similar figures for the preceding year shows that employment on roads in national parks and forests, and public lands remained at substantially a constant level, while there was an increase of 11 percent in the regular Federal-aid highway and grade-crossing elimination work. The decrease in employment is due almost entirely to the near exhaustion of emergency funds.

ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 1939	13
Not so many years ago highway construction almost ceased in the winter months except in the Southern States. A special effort to stimulate winter employment in the emergency program produced a definite increase that has been well sustained up to the present time. In the past year employment on work with Federal funds reached its lowest level in February, but even then it amounted to 38 percent of the figure for July.
The total employment for the year on work supervised by the Bureau—1,121,007 man-months—is the equivalent of an average full-time employment each month of 93,417 men. Industrial employment in the production and transportation of equipment and materials is estimated at 1.6 times the direct employment for work of the character done during the year, indicating an industrial employment of 1,794,000 man-months, and this, added to the direct employment, gives a full-time employment of 2,915,000 man-months, the equivalent of the full-time continuous employment of 243,000 men.
There was a slight increase over the preceding year in men employed on State construction not involving Federal funds and also in State maintenance forces. The total employment on work with State and Federal funds amounted to 3,149,342 man-months, or about 4 percent less than in the fiscal year 1938.
MILEAGE OF FEDERAL-AID SYSTEM
The Federal-aid system was designated as a result of the Federal Highway Act of 1921, and in accordance with the intention of the act there has been close adherence to the original system. Only minor revisions have been made to meet unforeseen conditions. The mileages have been changed slightly from year to year as estimated mileages or mileages along old roads have been replaced by the measured mileage on new construction.
The original system was limited to 7 percent of the rural road mileage within each State. When provision has been made for improvement of 90 percent of the designated system, an additional 1 percent is permitted and further additions are permitted on the same basis. This provision is becoming of increasing importance and has been taken advantage of by 25 States. During the past year the mileage of the system outside of Federal reservations increased by 1,704 miles due almost entirely to extensions beyond the original 7 percent.
The system in any State may exceed what would otherwise be the limiting mileage by an amount equal to the mileage of the system within Federal reservations. Additions to the system in reservations amounted to 628 miles bringing the total additions for the year to 2,332. System mileages by States are shown in table 4.

STATUS OF MAJOR FUNDS AND PROGRESS IN CONSTRUCTION
During the year construction work on 13,482 miles of highway was brought to completion, exclusive of work done in Federal areas and with special funds. The completed work included 9,786 miles on the Federal-aid system outside of municipalities, 586 miles on extensions of the system into and through municipalities, 139 miles of secondary or feeder roads in municipalities, and 2,971 miles of secondary or feeder roads outside of municipalities. Payments to the States for construction completed amounted to $186,718,071, as shown in table 5.

Details concerning the status of the various funds by States and by classes of highways are shown in tables 6 to 9. The mileages of highway according to status, by States, and by class of highways are shown in tables 10, 11, and 12. Similar information for gradecrossing work is shown in table 13. Tables 14, 15, and 16 show the mileage by types in the different stages leading up to completion. The tables are so arranged that each shows all funds or all mileage in a given status.
PUBLIC WORKS AND WORKS PROGRAM HIGHWAY CONSTRUCTION
These emergency programs to provide employment have been financed with authorizations totaling $800,000,000 made in the calendar years 1933-35. The highway work with these funds was very nearly completed in preceding fiscal years. The accomplishment of the past year is, therefore, small.
In the combined emergency programs, and including the length of road surfaces improved in the emergency program of grade-crossing elimination, 564 miles were improved. This mileage included 117 miles in the Public Works program, 358 miles in the Works Program, and 89 miles of surface in connection with Works Program gradecrossing eliminations. Details concerning this work will be found in tables 6 to 12.

PROGRESS IN FEDERAL-AID ROAD CONSTRUCTION
Improvement of the Federal-aid system was carried on with funds remaining from the previous fiscal year and under an authorization of $125,000,000 for 1939 provided by the act of June 16, 1936. The apportionment of this fund was shown in the last annual report.
During the year 10,057 miles of highway financed with $128,220,989 of Federal-aid funds were brought to completion. These projects involved $121,629,657 of State funds. Payments to the States for completed work, including work done on projects still under construction, amounted to $117,719,749.
At the close of the year projects under contract and in large part under construction included 7,295 miles of highway at an estimated cost of $227,324,289 to be provided as follows: $113,121,919 Federal-aid and $114,202,370 from State funds. At the same time projects had been approved, but not yet contracted for, covering 2,110 miles, and involving $23,819,863 of Federal-aid funds and $24,615,523 of State funds.
On June 30, 1939, there remained available for new projects $133,629,011 of Federal-aid funds. In greater part they were funds provided for 1940. Tables 6 to 12 show the status of the work by States.
PROGRESS IN CONSTRUCTION OF SECONDARY ROADS WITH FEDERAL AID
Improvement of secondary roads as a part of the regular Federal-aid was begun in the preceding fiscal year with an authorization of $25,000,000 and an equal amount was made available for the past fiscal year. It is required that these funds be matched with State funds according to the usual Federal-aid plan.
In a number of States this work has not been prosecuted at the rate permitted by Federal funds. Where State funds have been insufficient to permit expenditures on secondary roads or where authority for such expenditures has been lacking, local authorities have been asked to raise required amounts and place them under State control.
Lack of State funds with which to match Federal-aid for secondary roads is still retarding this work, but there was a considerable gain in momentum during the past year when 2,717 miles were completed. At the end of the year 2,315 miles were under contract and 555 miles were approved but not under contract. The mileage completed cost $28,755,838, the Federal Government contributing $14,268,844 of this amount. The mileage under contract is to cost $31,693,820 of which $15,721,517 is to be Federal-aid. The projects approved but not under contract are estimated to cost $6,607,416 and $3,110,405 has been assigned as Federal-aid. Tables 6 to 12 show the status of the work.
The cost of secondary roads in this program has varied greatly, being particularly influenced by local conditions and by availability of suitable materials.
PROGRAM OF GRADE-CROSSING ELIMINATION AND PROTECTION
The accomplishment of the year in eliminating 382 railroad-highway crossings, reconstructing 86 obsolete separation structures, and in protecting 438 crossings by signals or other safety devices is an

important contribution to highway safety and will save much delay and inconvenience to public travel. A portion of the work done was in the emergency program of grade-crossing elimination financed by $200,000,000 authorized by the Emergency Relief Appropriation Act of 1935. In this program 173 crossings were eliminated, 38 elimination structures were reconstructed, and 154 crossings were protected. Costs were met almost entirely with Federal funds which amounted to $23,557,056. The fact that more than half of the expenditure was in municipalities reflects the relatively greater dangers and delays at city and suburban crossings.
In the regular Federal-aid program of grade-crossing elimination initiated in the preceding year, and for which $50,000,000 was authorized for each of the fiscal years 1938 and 1939, 191 crossings were eliminated, 48 existing structures were reconstructed, and 258 crossings were protected. Federal funds involved in this work amounted to $15,630,604.
Since the Public Works program started in 1933, 2,938 crossings have been eliminated and 434 obsolete elimination structures have been reconstructed. The most dangerous and, therefore, the most important grade crossings are rapidly being done away with in every State. The substantial program of railroad-highway grade-crossing elimination is considered one of the most advanced and productive undertakings of the present period of highway development.
At the end of the year work under contract consisted of 453 crossing eliminations, 75 elimination structures being reconstructed, and 947 crossings being protected. Table 13 shows details of the work by States and also the number of projects approved but not under contract at the end of the year.
SUMMARY
The year’s work with the funds apportioned to all States resulted in the completion of 13,482 miles of highway and the elimination of 382 railroad-highway grade crossings, the reconstruction of 86 gradeseparation structures, and the protection of 438 crossings at a cost of $196,566,311 in Federal funds and $139,524,945 in State funds. The types of highway completed are shown in table 14.
The completed work was divided as follows: 9,786 miles on the Federal-aid system outside of municipalities, 586 miles of extensions of the system into and through municipalities, 139 miles of secondary roads in municipalities, and 2,971 miles of secondary roads outside of municipalities. Federal funds involved in the respective classes of work were $135,452,188, $27,187,758, $10,470,759, and $23,455,606.
The roads under contract at the end of the year totaled 10,012 miles and involved $183,723,534 of Federal funds, and there were 2,718 miles approved but not yet contracted for, involving $34,465,125 of Federal funds. Unobligated balances available for new’ work totaled $228,180,129, in large part newly apportioned funds for the fiscal year 1940. Tables 15 and 16, respectively, show the types of road under contract and the types approved but not yet under contract.

52	BUREAU OF PUBLIC ROADS
CONSTRUCTION OF ROADS THROUGH PUBLIC LANDS AND FEDERAL
RESERVATIONS
Special authorizations and appropriations have been made by Congress for the survey, construction, reconstruction, and maintenance of main roads through unappropriated or unreserved public lands, non-taxable Indian lands, and Federal reservations other than the forest reservations, where such land is more than 5 percent of the total area of the State. There are 14 of these Federal-land States, all of them west of the Mississippi River. The percentage of such lands in the several States varies considerably and reaches a maximum of approximately 73 percent in Nevada.
The construction of highways across these relatively large areas that do not contribute to State revenues imposes a serious burden on State highway funds.
The Federal-land highways differ from the forest highways and the Federal-aid highways in that there is no Federal-land highway system. Federal-land funds may be expended on roads which are on the Federal-aid system or on main roads not on the Federal-aid system. Contributions from the States are not required to be used in conjunction with Federal-land funds, but cooperative funds from the States may be used. Federal-land funds are sometimes expended under the supervision of State highway departments, following Federal-aid procedure, and sometimes under the detailed supervision of this organization.
Authorizations for the construction of roads in public lands have been made by eight congressional acts, passed up to the end of the fiscal year 1939. Authorizations have been made available for each fiscal year from 1931 through 1941, with the exception of 1932 and 1937, and total $23,000,000. The authorization for 1939 was $2,-500,000; for 1940, $1,000,000; and for 1941, $2,000,000;
Federal-land projects, in large part, involve the grading and draining of new roads and the reconstruction of old roads to greater widths and to higher standards of grade and alinement. Most of these roads are subsequently improved by the addition of gravel and bituminous surfacing. In the effort to spread the relatively small funds over a considerable mileage of road, very little mileage of the higher types of surface, such as bituminous concrete and portland-cement concrete, has been constructed.
During the fiscal year 244 miles of road were brought to completion, and at the end of the year 200 miles were under construction or had been contracted for. The total improved mileage at present is 1,623 miles. Tables 17 to 20.show details concerning work completed during the year and the status at the end of the year.

The Bureau has continued to supervise other projects involving the reconstruction of flood-damaged bridges at the request of the Works Progress Administration. These projects are financed by that organization and the States and, in some instances, partly with Works Program funds administered by the Bureau. Flood-damaged bridges and bridge approaches are reconstructed for the most part on secondary roads. In this work, which is done by contract, the Bureau cooperates closely with the State highway departments much the same as on Federal-aid construction.
During the year 3.2 miles of bridges and approaches costing $3,250,-950 were completed. This brings the total of this class of work completed to 38 miles costing $12,283,140. At the close of the year work estimated to cost $250,000 was under contract as shown in table 22.

Federal funds to aid the States in the immediate repair of highways and bridges on the Federal-aid system damaged by floods or other forces of nature have been made available by two congressional acts. The Hayden-Cartwright Act of June 18, 1934, authorized $10,000,000, and the Federal Aid Highway Act of 1938, authorized $8,000,000 from
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 3 9	55
any funds available for expenditure under the Federal Highway Act and authorized future appropriation of funds to replace the funds expended for such purposes. These acts make possible the immediate repair of damaged roads and bridges without waiting for specific authorization of funds. The States are required to match these funds in the same manner as regular Federal-aid funds.
Work was completed on 31.2 miles costing $2,759,748 during the year, as shown in table 23. Work estimated to cost $4,124,118 was under contract, and work estimated to cost $448,960 was approved but not yet under contract. Funds paid to the States during the year under this authorization amounted to $1,704,554, bringing the total paid to the States under the Hayden-Cartwright Act to $4,274,430.

WORK-RELIEF HIGHWAY PROJECTS
Work-relief highway projects, begun in the fall of 1933 to relieve distress in drought-stricken areas, have been continued. Road work has been carried on by an arrangement under which the Federal Emergency Administration of Public Works has granted funds to pay material and equipment costs, limited to not more than 30 percent of the total cost, and the labor has been supplied from relief rolls and paid first by the Federal Emergency Relief Administration and later by the Works Progress Administration.
56
BUREAU OF PUBLIC ROADS
The Bureau, cooperating with the respective State highway departments, has assumed the responsibility of supervising road work under this arrangement.
During the year 625 miles of this kind of work costing $3,824,253 was completed, bringing the total to date to 7,014 miles. Work was under contract at the close of the year on 414 miles, estimated to cost $5,505,828, as shown in table 24.

The Federal Emergency Administration of Public Works has continued the policy of aiding, by loans or grants or both, the construction of roads and bridges in a number of States. Projects of this kind are initiated by their sponsors with the administration and, after agreement has been reached and funds allotted, are turned over to the Bureau for detailed administration of construction. Practically all of this work is done by the contract method.
This work was begun in 1934 with funds provided by the National Industrial Recovery Act and has been continued with funds allocated under authorization of the Emergency Relief Appropriation Act of 1935 and the Work Relief and Public Works Appropriation Act of 1938. At the close of the fiscal year loans and grants of $76,816,461 had been made for specific projects 17,238 miles in length and estimated to cost $174,746,773. This represents a net increase during the year of 7,760 miles involving $20,380,189 of loan-and-grant funds and estimated to cost $48,355,522. Details by States are shown in table 25.

NATIONAL-FOREST ROAD CONSTRUCTION
Improvement of the system of forest highways of 21,981 miles located in 36 States, Alaska, and Puerto Rico was continued during the year when 413 miles were brought to completion under Bureau supervision. However, much of the work was further improvement of previously improved roads, and only 164 miles were improved for the first time.
When the improvement of forest roads and trails with annual authorizations began 23 years ago, the forest areas were almost inaccessible to wheeled vehicles. During the first years of improvement, the construction was almost entirely of the pioneer type. As improvement of main highways throughout the country advanced, the standards of forest-highway improvement were raised. When the Federal-aid and State highway systems were designated, it became necessary to designate and provide for the improvement of routes across forest areas forming essential links in these systems. Thirty-nine percent of the forest-highway system as now constituted provides necessary links in the Federal-aid system, and another 39 percent is similarly related to portions of State systems not on the
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 3 9	59
Federal-aid system. As improvement of these systems has progressed, there has been strong pressure to open the impassable sections through the forests. To accomplish this, with the funds that have been available, many miles of road have been built according to the principles of stage construction. The first stage has included only a partial provision of the improvement known to be ultimately desirable but has been so designed that further improvements may be provided in successive steps as funds are provided.
At the end of the fiscal year, work had been done on 6,832 miles, or 31 percent, of the forest-highway system. The greater portion of the system is still unimproved, but greatly increased use of the surfaced sections, increase in speed of vehicles, and a general raising of highway standards have made necessary a concentration of present efforts on the modernizing of those highways built in the early stages of the program. Of the 413 miles completed in 1939, 249 miles were second- or third-stage improvement, and work was done for the first time on 164 miles. The existing forest highways are being raised to higher standards and are attracting increasing thousands ot tourists each year, but extension of the surfaced mileage in the system is progressing at a slow pace.
Construction of forest highways, within the limits of Federal funds authorized, is not contingent upon the provision of State or local funds, but in past years the State and local interest in obtaining construction of particular roads has led to the provision of cooperative funds that have materially accelerated the program. In the past few years, there has been a marked decrease in the amount of State and local funds offered for use on forest roads, and the program has been supported almost wholly with Federal funds. This is partly explained by the small mileage of entirely new construction. Communities adjacent to the forests have a stronger interest in the opening up of new routes than in betterment of routes already open to travel.
The work done under the direction of this Bureau and reported here includes all improvements classified as major. Minor road improvements are administered by the Forest Service. Major projects include all work on the forest-highway system except those that do not require the technical services of a highway-engineering organization or those having an estimated average cost of less than $2,000 per mile. Forest-development road projects of an estimated average cost greater than $5,000 per mile, and those requiring the services of a highway-engineering organization are also classed as major projects.
Authorizations for forest-road work have been at the rate of $14,000,000 annually in the fiscal years 1938 and 1939, and $10,000,000 for 1940.
At the beginning of the year the active program involved $10,224,-747, of which $6,825,767 was involved in work under contract and force account construction, $1,647,091 in surveys, $1,426,578 in maintenance, and $325,311 for miscellaneous items. There was available for new work $16,758,024, of which $6,728,897 was for programmed work not under contract, and $10,029,127 was available for additional new projects. Of the latter amount $8,180,139 has been assigned to major projects and $219,429 to minor projects during the year, leaving a balance of $1,629,559 available at the end.of the year for new* projects. The amount of $10,029,127 consists of

$6,666,667 authorized by the act of June 8, 1938, for the fiscal year 1940, apportioned December 27, 1938, and $3,362,460 from previous apportionments.
Major work to cost $8,657,996 was put under contract, and the roads completed cost $8,026,652.
At the close of the year the forest-road work amounted to $10,-856,091, of which work under contract and force-account construction was $7,815,957, surveys $1,448,368, maintenance $1,237,599, and miscellaneous items $354,167. The amount available for new work was $7,880,599, of which $6,251,040 had been assigned to specific projects then placed under contract, and $1,629,559 was available for additional projects. These amounts include the $10,000,000 authorized for forest-road work in the fiscal year 1940.

ROAD CONSTRUCTION IN NATIONAL PARKS AND MONUMENTS
National parks and monuments have been established in 33 States, the largest and best known being in the Western States. These areas of exceptional natural phenomena and places of particular historic significance and scenic beauty are recreation grounds for the entire Nation. Nature and events in past history have provided places that everyone desires to see, and highways are the primary requirement in making them accessible to thousands of people who must plan vacation trips of moderate cost.
In addition, over 900 miles of parkways have been established by Congress in the East. These parkways connect points of special interest to tourists and are located on a right-of-way sufficiently broad to give complete control of roadside development. One follows closely the crest of the Blue Ridge Mountains between the Shenandoah National Park in Virginia and the Great Smoky Mountains National Park in North Carolina. Another follows the old historic trail between Natchez, Miss., and Nashville, Tenn.
The construction of roads in and approaching national parks, monuments, and parkways is a responsibility of the Bureau under an agreement with the National Park Service. Highway construction in national parks and monuments is carried on with the cooperation of the Branch of Plans and Design of the National Park Service in locating and planning highways to fit them into and preserve the natural beauty of the parks.
At the close of the year, 1,577 miles of road had been constructed in the national parks and monuments, an increase of 146 miles during the past year. This mileage includes both approach roads and parkways. In addition, 143 miles of road previously constructed were further improved, in most instances by placing a better surface. The completed mileage is shown by parks and monuments in table 30, and by types in table 31.

In Grand Canyon National Park the grading and base-course construction of the northern approach from Jacobs Lake to the north rim of the canyon were completed. Funds have already been allotted for a bituminous plant-mix surface on this highway. In Mount Rainier National Park both the Westside and Stevens Canyon routes, which are of considerable length, are being improved by including sections in each year’s program. Work is now being concentrated in Stevens Canyon. In Crater Lake National Park the last section of the loop around the lake between Government Camp and Kerr Notch is approaching completion. In Yosemite the Big Oak Flat road route, involving difficult location and construction, is completed. The tunnels on this route are being lined and sections between these tunnels are being surfaced. There still remains a long uncompleted gap on the Tioga Road in Yosemite. This is a superb mountain highway through some of the most rugged of the high Sierras, crossing the Sierras at Tioga Pass at an elevation of nearly 10,000 feet. Additional work on this road is planned. Roads within Yellowstone National Park and the approach roads from the east and northeast are being improved. Another section of the Fresno-General Grant Approach Road was completed, leaving only one more section, about 5 miles in length, to be built in order to complete the highway.

In the Eastern States attention is being centered on the construction of parkways. The Blue Ridge Parkway following closely the crest of the Blue Ridge Mountains for approximately 480 miles passes through Virginia and North Carolina and connects the Shenandoah and Great Smoky Mountains National Parks. Approximately 134 miles has been completed and 170 miles is under construction. A portion of the mileage under construction is surfacing of roads previously graded.
The Natchez Trace Parkway passes through historic sections of Mississippi, Alabama, and Tennessee for approximately 455 miles. Approximately 36 miles of this parkway are now complete, and 11 additional miles are under construction.
Mileage of highways under construction is listed by location and types in table 32.

INTER-AMERICAN HIGHWAY
For some years the Government of the United States has assisted Central American countries in the improvement of the highway from the southern border of Mexico to Panama City, Panama, which is a part of the projected route from Laredo, Tex., to Panama City. The cooperation has been through the Department of State, the Bureau of Public Roads supplying the needed engineering services and direction. In 1934 a route was recommended after a careful reconnaissance survey. Recent activity by this Government has been supported by an authorization of $1,000*000 made in 1934 for cooperation in the survey and construction of highways. Surveys have been made in several countries, and assistance was given to Panama, Costa Rica, Nicaragua, Honduras, and Guatemala in the erection of bridges.
During the year the bridge construction was largely completed, and the giving of engineering advice and assistance was continued under an authorization of $50,000 made in June 1938.
The Chiriqui Bridge in Panama and approaches were completed in March 1939, and the structure was formally opened by the President of the Republic during a special fiesta proclaimed for the purpose. Panama is obligated under a cooperative arrangement to erect the Rio Chirigagua and the Rio San Cristobal Bridges between David and Conception. Steel for these bridges has been supplied by the United States. The substructures for both of these spans had been completed and arrangements were made for the erection of steel in May 1939, but erection has been postponed until the next dry season/ There is reluctance in Central America to carry on hazardous work during the rainy season.
In Guatemala, bridges over Rio Tiucal, Rio Zonjon, and Rio Mongoy were finished by local forces.
Engineering assistance was given in the construction of 12.5 miles of road in Guatemala, 18 miles in Nicaragua, and .25 miles in Costa Rica. The Nicaraguan section of road was practically complete in June 1939. The work in Guatemala is expected to be completed soon. Steady progress has been made on the 25 miles of construction in Costa Rica between Cartago and San Marcos. This highway crosses the Continental Divide at an altitude of approximately 7,200 feet, over a range of mountains having very precipitous slopes and at places the material is very unstable. Several months more will be required to complete the work.
The cooperative work of the United States has aroused a strong interest in Central American countries in the Inter-American Highway, and several countries are planning, on their own account, to extend or reconstruct sections of the route. During the past fiscal year requests for additional surveys have been received from Nicaragua, Honduras, and Guatemala. All needed survey work in Panama was completed in the preceding year.
The survey requested in Nicaragua between Las Maderas Bridge and the town of Sebaco, a distance of 22.5 miles, has been completed, and construction should begin during the present year.
In Honduras, 34 miles were surveyed from the Choluteca Bridge westward to the Nacaome River. This section of road passes through all of the largest towns on the Pacific side, including San Lorenzo, the only Pacific port of entry.

BUREAU OF PUBLIC ROADS
In Guatemala, surveys on 89.5 miles of road between Asuncion Mita and Guatemala City were completed. A passable highway exists throughout this section, but it has sharp curves and some bad location that can be rectified. This survey completes the detailed planning of the route from Guatemala City to the frontier of El Salvador.
All road plans resulting from surveys have been drafted according to the standards used on Federal-aid work in the United States, and the plans will be furnished to the respective countries for their use in continuing construction.
Table 34 indicates the condition of the Inter-American Highway from Laredo, Tex., to the Canal Zone at the close of the year.

During the year Bureau engineers have been loaned to Venezuela, Colombia, and Ecuador, under provisions of the acts, Public No. 545, Seventy-fifth Congress, and Public No. 63, Seventy-sixth Congress.
An engineer was assigned to Venezuela in January 1939, for 6 months, to advise regarding the location of new roads. An American contracting concern has notified the Bureau that it has contracted for approximately 150 miles of road recommended by our engineer.
A soil expert was assigned to the State of Cundinamarca, Colombia, which includes the Federal district and the capital of that Republic. His assignment for 3 months has been extended for a second like period.
In June 1939, an engineer was furnished the Republic of Ecuador, on request of that Government, to advise on a general system of improved roads, and at the close of the fiscal year he was engaged in that work.
On May 25, 1939 the Export-Import Bank of Washington officially requested the Secretary of Agriculture to arrange for the assignment of engineers from the Bureau of Public Roads to assist the bank in connection with the extension of credits for public road construction in Latin America. Authority for such assignments was given by the Secretary of Agriculture, and negotiations covering details were in progress at the close of the year. In this connection a request has been received for the assignment of an engineer to Paraguay.
In January 1939, the Third Pan American Highway Congress was held at Santiago, Chile, and a representative of the Bureau was designated as the technical head of the American delegation.
The Congress took steps to obtain concerted action by the several countries of South America in designating a Pan American highway

system to connect at Panama with the highway projected from the United States and to establish the necessary international highway connections throughout the southern continent.
JJnder the Pan American Highway Convention, signed at Buenos Aft-es in 1936, a financial committee was created and the Bureau has cooperated with the American representative of this committee by furnishing estimates and information pertinent to its work.
Under that same convention, the Bureau was officially designated by the Secretary of State as the depository for exchange of highway information, with similar agencies designated for each of the Latin American countries.
TRANSPORTATION, ECONOMIC, AND STATISTICAL INVESTIGATIONS
HIGHWAY-PLANNING SURVEYS
At the close of the year 46 States and the District of Columbia had undertaken State-wide highway-planning surveys in cooperation with the Bureau under authority contained in the Hayden-Cartwright Act of 1934 and subsequent legislation which authorized the Secretary of Agriculture to approve allotments of not to exceed 1/2 percent of the amount of Federal highway funds apportioned for any year for surveys, plans, and engineering, and economic investigations of projects for future construction.
In a number of States preliminary reports have been prepared summarizing portions of the data for the guidance of the legislature in connection with specific proposals, or to aid the State highway departments in setting up yearly programs. In several States work has been started on a comprehensive initial report, summarizing and correlating the data obtained in all phases of the survey, following in general an outline suggested by the Bureau. While few comprehensive reports have yet been completed, highway officials in all States are making constant use of the information in connection with problems that arise from day to day.
One of the most generally useful products of the planning surveys is a series of large-scale State and county maps. The county maps, generally on a scale of 1 inch to 1 mile or greater, show, in addition to transportation facilities, all physical features and man-made improvements, and will form the first up-to-date and comprehensive series of county maps ever made. At the end of the year there had been approved 2,962 sheets covering 1,924 counties, approximately 70 percent of the total to be completed. Other series of maps to be drafted on the base maps show highway and other transportation systems, bus and truck routes, postal routes, school-bus routes, and traffic volume.
There has been an increasing public demand for these maps, and many requests from private agencies and individuals have been received by the States concerned. Arrangements have been made with the States to supply copies or complete sets to a number of Federal agencies, including the Library of Congress, the Soil Conservation Service, the Agricultural Adjustment Administration, the Farm Credit Administration, and the Bureau of the Census. These maps are also used by the Rural Electrification Administration which makes tracings from copies of maps furnished for their studies.
In cooperation with the Bureau of the Census, boundary limits around the settled areas of unincorporated urban communities of 800
70
BUREAU OF PUBLIC ROADS
or more population have been established by the planning surveys in 29 States. The maps will show these boundaries, which will be used in the 1940 census, making possible, for the first time, census reports for such unincorporated settlements.
Field surveys, which form the basis of the map work, and also an inventory of the present extent and condition of all rural roads have been completed in 43 States, covering an aggregate of 2,748,853 miles In 3 other States, with an estimated road mileage of 133,258, the mileage inventoried to June 30, 1939, was 118,375, leaving only 14,883 to be completed.
The surveys include collection of data on sharp curves, steep grades, sight distances, and banking of road surface on curves, on the primary highways with the location and nature of .critical restrictions. These data are assembled in two groups: (1) Nonmountainous roads having sight distance of less than 1,000 feet, curvature exceeding 6°, grades exceeding 5 percent; (2) mountainous roads having sight distances less than 650 feet, curvature exceeding 14°, grades exceeding 8 percent. These data will reveal critical sections of the highway system requiring early attention and, when correlated with traffic density and accident records, will indicate the priority that should be given projects in improvement programs. Nearly all of the field work and most of the initial tabulations have been completed.
In cooperation with the Association of American Railroads, pertinent facts relating to rural and urban grade crossings are being supplied which will be combined with data from a field inventory of the crossings and traffic counts to arrive at a priority improvement program. Most of the data to be supplied by the railroads have been received and await completion of the urban-crossing inventory. About half the field work has been completed.
Field work on the traffic surveys has been completed by all but 9 States. At 3,237 loadometer and pit-scale weighing stations, the weights of trucks, commodities carried, and other data were recorded for thousands of trucks, tractor-truck semitrailers, and trucks with full trailers. Information on the flow of weight over the highways will be obtained from the loadometer stations, while more detailed and precise data will be obtained at the pit-scale stations to determine loading practices as related to regulation and taxation. Information regarding the weights and dimensions of busses and number of passengers carried is also obtained at these stations. Large-scale traffic maps have been completed for all counties in 7 States, and active work is under way in the preparation of such maps in 15 other States which have submitted advance copies for approval as to form and method. State traffic maps covering the primary road system and important local roads have been completed in final form in 4 States and in preliminary form in 17 other States.
There are now installed 411 automatic traffic-recording machines, recording the number of vehicles passing hourly. The design of these units was originally conceived by the Bureau and later perfected by commercial organizations. Installed at strategically located points, these machines provide a long period record of traffic volume. Completeness of the records permits the determination of characteristic traffic patterns and factors with which to expand short-period counts to annual averages and to show minimum, average, and maximum traffic volumes.
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 1939	71
Supplementing these permanently located machines and also making it possible to reduce the number of manual counts, a number of States are now using portable automatic recorders, most of which have been constructed according to plans developed by the Bureau in its studies of motor-vehicle performance.
The financial surveys, which include four closely related studies, consist of the collection and analysis of information regarding the ability of the State to finance the highway program. In the fiscal study, complete data on income, expenditure, and debt of the State and all governmental subdivisions such as counties, townships, municipalities, school districts, and highway districts have been collected for a typical 1-year period. These studies will indicate the importance of highway transactions in comparison with other activities such as general government, education, and public welfare. They will show the present source of highway funds and will indicate where and how these funds are spent.
The road-use studies provide information regarding the relative use of the rural highways and streets by the different classes of motorvehicle owners resident in various rural and urban classifications. Summarization of these data obtained from approximately 650,000 personal interviews with vehicle owners and operators, when correlated with results of the fiscal study, will indicate the relationships existing between contribution to highways and the benefits derived through their use.
The motor-vehicle-allocation study, based on analysis of more than 3,300,000 questionnaires, shows the registered location of motor vehicles and the proportionate amounts of gasoline taxes and license fees paid by residents of cities, towns, and rural areas. This information will be used to determine the amounts that may be anticipated from such sources in the future.
The road-life study consists of an analysis of the life of various types of surfacing and roadway elements on the State highway system. Data from the records of State highway departments form the basis of actuarial studies which will indicate the average service lives that may be expected from the several types of highway surfaces as well as the other elements of the highways such as earthwork, drainage structures, shoulders, bridges, and guardrail. This information, supplemented by analyses of construction and maintenance costs and salvage values, will make possible reliable estimates of the amount and cost of highway replacement and construction that will be required each year in the future. The highway construction and reconstruction program may then be scheduled over a period of time to correspond with funds likely to be available in the future for highway purposes.
Information regarding land uses, present and potential, will be obtained from the Department’s land-use-planning program now under way in most of the States and involving the participation not only of many Federal and State agencies but of farmers as well. This work will provide a classification of the best uses of land by small local areas and will permit highway plans to be more closely correlated with those for agriculture.

ECONOMICS OF TRANSPORTATION
Shortly after the inception of the highway-planning surveys, the Bureau materially augmented its studies of the economics of transportation. In the planning of highway systems for the Nation, the States, and the individual counties and communities, as must be done in the future, careful consideration should be given to the economic and social activities served and to be served. In determining the extent to which highway transportation is economically sound and defensible it cannot be considered apart from other modes or kinds of transport. The transportation problem as a whole must be carefully studied, utilizing such materials as are available from other official sources, the results of the highway-planning surveys, and other special studies and analyses.
The work on economics of transportation has involved the preparation for use by the cooperating States of tables presenting the essential data on population, agriculture, industry, mining, and trade in each county; tables and maps for division of the States into areas of similar economic characteristics for use in analyzing traffic-count data; percentage factors by counties based on population and economic data to provide the States with a factual basis for equitable allocation of Federal-aid secondary mileage among the counties, and critical analyses from the economic viewpoint of allocation proposals made by the States; and outlines for detailed study of individual counties and county analyses to demonstrate to the States the data available and their use in determining present and probable future road needs.
Studies of truck movement of commodities have been developed from the loadometer data in Franklin County, Ohio, Baltimore, Md., and truck movement to and from ports. A special study has been outlined and put under way on the relation between income and population (changes and trends) and motor-vehicle usage (registration, gasoline consumption, costs, and expenditures).
A detailed continuing study will determine the relation between industrial relocation, decentralization and other industrial changes, and the need and demand for transportation (kinds, amounts, length of haul, costs, rates, etc.). This is an intensive, comparative, and analytical study designed to show the relation between the various modes of transport; the changes in demands on the various transport agencies due to industrial and economic changes and shifts; the influence of changes and improvements in transportation facilities on population, industry, agriculture, trade, and employment; and the relative adequacy of various transportation agencies and how transportation planning may be used as a directive force in industrial development.
An important part of the work has been conferences with other organizations and individuals on transportation problems, recommendations as to additional statistical data needed, and the stimulation of research by others.
SAFETY RESEARCH
Studies in highway safety, initiated under authority of the act of Congress approved June 23, 1936, were practically completed. Although full reports on a number of research projects previously have been transmitted to Congress, several unfinished studies necessitated the continuation of the cooperative research with the Highway
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 3 9	73
Research Board through the year. Final reports on these studies, including particularly an investigation of the validity and utility of driver test clinics for identifying or indicating needed education of the accident-prone motor-vehicle driver, were in preparation at the close of the year.
MAINTENANCE-COST STUDIES
Agreements with the State Highway Departments of Connecticut and New Hampshire, and the Department of Public Works of Rhode Island for a study of highway-maintenance costs in relation to traffic volume were renewed for the fifth year’s work. Traffic records for the fourth consecutive year were obtained for 33 sections of highway in Connecticut, 52 sections in New Hampshire, and 102 sections in Rhode Island. The annual cost of general highway maintenance for various items on each section is being kept by the States and detailed records on traffic are being compiled.
The objective of this study is to determine the maintenance costs for the different types of road, surface in relation to the traffic carried and various other items. Due to nonperiodic or infrequent costs of maintenance incurred, no determinations can be made until the records have been kept for a period of at least 5 years.
HIGHWAY-CAPACITY AND VEHICLE-PERFORMANCE STUDIES
Data collected in the field studies conducted last year in cooperation with the Illinois highway-planning survey and in previous field studies were analyzed and the results published.
Studies of the performance of trucks on highway grades were continued. The studies so far have involved only new trucks, which were given exhaustive tests on two grades located on route U S 40 east of Baltimore. From the results of these tests it is possible to compute accurately the performance of a given vehicle on any given grade. The results will also be used to evaluate other less exhaustive methods of test. These methods include the acceleration method, dynamometer tests, and various performance meters. One of these methods will be selected to test a much larger number of used trucks typical of vehicles in service on the road.
Twenty-two vehicles have been tested thus far. Several manufacturers have furnished the trucks and in most cases the driver, and have also delegated an automotive engineer to inspect the work and offer advice. The Quartermaster Corps of the War Department has made available the facilities of the Holabird Quartermaster Depot, which include a gasoline supply, storage of trucks and equipment, dynamometer laboratory, and machine shop, and the Army automotive engineers have been available for consultation and assistance. The National Bureau of Standards has rendered considerable assistance in a consulting capacity. J. T. Thompson, of Johns Hopkins University, has also acted as consultant, and the university has furnished space and equipment for the analysis of field data. A complete description of the tests and the procedures involved were reported to the Highway Research Board in December 1938 and published in Public Roads, February 1939.
The development of satisfactory equipment for the detailed study of the movement of vehicles and of passing practices has been a difficult problem. These studies are made on a half-mile section of
74	BUREAU OF PUBLIC ROADS
highway and involve the measurement at 50-foot intervals of time and position of vehicles as they travel through the section. A new type of electrical road detector was developed, in which the electric contact is made by the displacement of air in a rubber tube laid across the roadway as a vehicle passes over it. Several miles of telephone and electrical cables were necessary, and six 20-pen time recorders were assembled in units to time and record graphically the impulses received from the road detectors.
Satisfactory field and office procedure has now been worked out in experimental tests, and arrangements have been made with interested State highway departments to cooperate in extensive field work during the coming year. At present, work is under way in Massachusetts and is scheduled in Illinois and Texas.
In the case of the study of lateral placement of vehicles on the highway, a similar development has taken place. Equipment has now been perfected and. consists of a road detector to measure the lateral placement at 1-foot intervals, and a speed meter which records automatically the speed of each vehicle passing. With this equipment it will be possible to determine the lateral position assumed by various types of vehicles traveling at various speeds on tangents, curves, and grades.
An outgrowth of the experimental work on equipment has been the development of a simple and very satisfactory automatic traffic counter which utilizes the pneumatic road detector. An adaptation of the counter has also been made which permits the independent counting of vehicles traveling in each direction. By using a road detector consisting of several units, it is possible to segregate and record, by traffic lanes, vehicles traveling in either direction as well as the total traffic, a development that is particularly useful in city traffic surveys.
NATIONAL CONFERENCE ON STREET AND HIGHWAY SAFETY
Active cooperation with the National Conference on Street and Highway Safety was continued. Early in the year the committee on uniform traffic laws and ordinances of the conference met to revise the five acts of the Uniform Vehicle Code and the Model Traffic Ordinances. Extensive changes in acts II and V of the code necessitated printing a new (1939) edition of these two acts.
A meeting was held of the joint committee of the National Conference on Street and Highway Safety and the American Association of State Highway Officials to revise the Manual on Uniform Traffic Control Devices for Streets and Highways. The recommended changes were published as a supplement to the 1935 edition of the manual.
With the cooperation of the National Bureau of Standards and a prominent manufacturer of pigments, a new supply of color cards was prepared by the Bureau, showing the correct shade of yellow for highway signs as prescribed by the manual. Samples of the color have been furnished to all State highway authorities for use in purchasing standard paints and enamels.

AMERICAN ASSOCIATION OF MOTOR VEHICLE ADMINISTRATORS
With the beginning of the year, the Bureau of Public Roads with the Automotive Safety Foundation and the National Conservation Bureau undertook to cooperate more closely with the American Association of Motor Vehicle Administrators, in order to promote more effective measures for assuring greater safety on the highways and greater freedom for interstate traffic.
Cooperative work has been specifically directed toward improving motor-vehicle inspection, driver examination, and reciprocity among the States, with respect to drivers’ licenses and registration.
A special group of investigators has been compiling the codes for motor-vehicle investigations and driver examinations, and it is expected that these will be ready for approval of the association and the Bureau following the annual meeting of the association in August.
The general trend toward compulsory motor-vehicle inspection conducted directly under the motor-vehicle administrations of the several States has made it desirable that effective and rapid methods of inspecting great numbers of vehicles be studied and devised, and so far as possible introduced into the several States in order to establish uniformity of requirements in the operation and efficiency of vehicles.
It is likewise desirable that more exacting requirements be adopted in the examination of drivers before granting permits to operate cars, and that these examinations be standardized and so far as possible made uniform with respect to methods and ratings in the tests of driver proficiency.
Both of these studies are fundamental to the development of the desired reciprocity among the several States with respect to the operation of motor vehicles.
In connection with the studies carried on to determine adequate methods of vehicle inspection, the Bureau and the association cooperated with the Society of Automotive Engineers in a series of brake tests which promise to be of great importance not only for the purpose of inspection of cars but in future brake design.
During the year, the Bureau took an active part in three of the four regional meetings of the association and intends to continue cooperating during the forthcoming fiscal year.
STATISTICAL RESEARCH ON ESTIMATING HIGHWAY-TRAFFIC VOLUME
As additional data on highway-traffic volume have become available from the highway-planning surveys, research on principles and methods of estimating traffic volume from short-time counts has been extended in several directions. The work is of importance because of the necessity of preparing traffic-flow maps for a great mileage of highway which must be based on many traffic counts. The duration and frequency of the counts should be held to the lowest practical minimum as a matter of economy.
A report on dispersion of highway traffic by time periods was made to the Highway Research Board, extending the analysis to hours of the day, days of the week, and months of the year, for the entire period of a year in each case. Study was also made of the variation in traffic by hours of the day for each month.
76
BUREAU OF PUBLIC ROADS
Traffic counts on 25 legs of 14 trunk-line crossings in Michigan, chosen as representative of traffic variation in that typical industrial State, are now being analyzed and studied. Counts by hours for a period of 1 year have been tabulated and are being analyzed. Extensive use of tabulating machines is making possible a thorough analysis of a large mass of data.
The problem of estimating traffic volume at low cost and with sufficient precision is now being attacked with a larger number of continuous counts from, a wider selection of typical stations. There are now available continuous counts at 3 stations in Maryland on local, county, and State highways by periods of 5 minutes for an entire year. These data will make it possible to determine the shortest count that may be safely used in estimating traffic. The 315,360 counts of 5-minute periods at the 3 stations were obtained with automatic traffic counters, and the analysis is being made almost entirely by mechanical means.
RAILROAD-ABANDONMENT STUDIES
The examination of dockets and reports in the files of the Interstate Commerce Commission covering the abandonment of railroad lines throughout the country was completed, and the abstracting of currently issued abandonment reports was kept up to date.
The data abstracted from the dockets and reports were largely assembled by States, tabulated, mapped, and in general prepared for the use of this Bureau and State highway officials in studying the abandonment of railroad lines. As of June 30, 1939, 1,275 abandonment cases had been examined since the inception of these studies, involving, 18,847 miles of railroad.
Beginning in March 1939, advance information concerning proposed railroad abandonment has been sent promptly to district engineers of the Bureau, upon the filing of abandonment applications with the Interstate Commerce Commission, thus assisting the field representatives of the Bureau in their consideration of requirements at grade crossings for signal devices or structural changes. Subsequently, uniformly arranged abstracts of the Commission’s reports have also been sent the district engineers when abandonments have been allowed.
The same advance information has been supplied to State highway officials to aid in present planning activities, and to encourage their study of the causes for and effects of changing railroad patterns as they bear on the whole transportation problem, and the demand for highway transport.
PHYSICAL RESEARCH
Previous annual reports have mentioned the new laboratories on the Mount Vernon Memorial Highway near Washington, where the physical research work of the Bureau is to be conducted. The buildings have been completed and the installation of laboratory equipment and furniture was well under way at the close of the year. The activities of the Bureau at the Arlington Experiment Farm of the Department will be, transferred to the new research station in the near future. The improved facilities for conducting a continuing research program and the assurance of a permanent location for field tests place this work on a much more satisfactory basis.
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 39	77
SUBSURFACE EXPLORATION
Study of various applications of the electrical resistivity and seismic methods of subsurface exploration to highway problems has been continued. A number of minor changes and improvements have been made in the seismic equipment tending to simplify electrical circuits, reduce weight, and better the performance.
In May 1939, in cooperation with the highway department of Iowa, a rather extensive investigation was made to determine the value of both the resistivity and the seismic methods of exploration for locating rock formations and gravel deposits as sources of road-building material. While the results of this survey will not be definitely known until more excavations are made at the places tested, the present indication is that both methods are useful in locating materials.
Several other Federal agencies are now making shallow explorations by the seismic method, essentially as developed by the Bureau, and the experience with it seems to be generally favorable. It is particularly adapted to reconnaissance surveys, and its use results in a great saving of both time and expense.
MOTOR-VEHICLE-IMPACT INVESTIGATIONS
Study of the relative elastic properties of concrete when subjected to comparable static and impact forces, applied by a vehicle wheel, has been actively pursued throughout the year. The special pendulum-type testing machine, described in the report for last year, and other equipment designed and built for this purpose have functioned well. This research is developing data of a fundamental character and the work is necessarily of a slow and painstaking nature. It constitutes an important part of a broad program of research, the aim of which is to rationalize the structural design of concrete pavements.
The data obtained are of sufficient scope to justify the issuing of a progress report at an early date.
MEASUREMENT OF ROAD-SURFACE ROUGHNESS
The degree of road-surface roughness is one of the major factors that determine the magnitude of the impact forces developed by motor vehicles.
This research has for its object the development of apparatus, instruments, and testing technique for quickly and reliably establishing an index of roughness for any road surface. There has been no universally accepted method for measuring the roughness of road surfaces in spite of the generally recognized need for such measurement.
The equipment that has been developed by the Bureau shows evidence of having reached a satisfactory state of development. However, thorough field trials remain to be made before it can be stated definitely that this equipment is ready to be offered for general use.
EROSION TEST FOR COATED CULVERT PIPE
The study of the erosion test for determining the quality of the bituminous coatings used on corrugated-metal culvert pipe has been continued. Experiments with both full-weight and reduced-weight erosive charges of cement-mortar cubes have been completed.
All data obtained, both in the cooperative check tests mentioned in previous annual reports and in the subsequent tests made by the Bureau, have been assembled and analyzed, and a report prepared.
78
BUREAU OF PUBLIC ROADS
The data indicate certain inherent deficiencies in the present method of test. The use of cement-mortar cubes appears to result in more consistent data than are obtained with other materials but does not overcome other undesirable characteristics of the test.
STRUCTURAL DESIGN OF CONCRETE PAVEMENTS
Work in this field of investigation has been continued along the lines described in previous annual reports. A more detailed study of the structural action of pavement slab corners has been found necessary. Because of climatic conditions, the work had to be done during the early summer months. It involved extensive strain measurements to determine the direction of critical stresses. A report on this special study is scheduled for the coming fiscal year, following the completion of the fifth report of the original series, mentioned in previous annual reports.
The supplementary study of dowel plate joints, mentioned in the last annual report, has been continued whenever favorable weather conditions obtained, and a considerable amount of valuable data has been accumulated.
An analysis has been made of the data obtained in the condition survey of the older concrete pavements in Michigan, a survey made in cooperation with the Michigan State Highway Department last year. The pavements examined ranged in age from 3 to 20 years, and their selection was based on the presence of factors, such as subgrade type, which might be expected to influence the pavement condition. The detailed data covering the history and present condition of 46 miles of selected pavement have been studied and analyzed, and a report is being prepared.
The construction of an experimental pavement in Indiana, in cooperation with the State Highway Commission, mentioned in the last annual report, was completed during October 1938. The purpose of this research project is to determine the desirability and economy of introducing longitudinal steel reinforcement to permit an increase in the length of concrete-pavement slabs. The slabs constructed in the experimental pavement range in length from 10 to 1,320 feet and the steel reinforcement varies correspondingly from a light welded fabric to an exceedingly heavy bar construction. The behavior of the different sections under the normal traffic conditions on a transcontinental highway and the climate of central Indiana will be observed in periodic surveys in which detailed measurements will be made on certain selected sections. Two sets of observations have been made. It is expected that a preliminary descriptive report of this project will be prepared for publication during the coming year.
STRUCTURAL DESIGN OF NONRIGID PAVEMENTS
Work on the complex problem of the structural design of nonrigid pavements has been directed principally toward the development of instruments for measuring the effect of static and moving loads upon plastic materials such as compose pavements of the so-called flexible type. Several different types of pressure-recording devices have been built and their characteristics studied. It is expected that the development of apparatus will be continued and that both field and laboratory experiments in pressure measurement will be started in the near future.

INVESTIGATION OF THE FATIGUE STRENGTH OF ARC-WELDED JOINTS
In investigating the fatigue strength of arc-welded joints the Bureau has been cooperating with the University of Illinois, the American Welding Society, and the welding research committee of the Engineering Foundation.
Engineers in this country have been slow to adopt the practice of welding in fabricating steel highway bridges because they have been uncertain about the behavior of welded connections, particularly when subjected to fatigue caused by alternating or pulsating stresses as occur in bridges. Because of this uncertainty, engineers have not taken advantage of the inherent economy in the use of welded structures.
A laboratory study of the fatigue strength of full-size welded connections is being made, and the results will be used to establish methods of design that will assure safe welded bridges.
A program of testing was drawn up by a committee representing the various interested parties, and testing at the laboratory of the University of Illinois has proceeded during the year. Significant results have already been obtained, and these results will be made available to engineers through publication in bulletins of the university.
This investigation will have a direct effect on future practice in bridge design and construction.
INVESTIGATION OF BRIDGE FLOORS
The investigation of bridge floors is being conducted cooperatively by the Bureau, the Illinois Division of Highways, and the University of Illinois.
In the past empirical rules have been used in designing highway bridge floors because of the lack of any rational method of analysis of stresses in floor systems. These rules are based upon very limited investigations and therefore many questionable assumptions have to be made in applying them. Uncertainties have been provided for by designs that may be overly conservative and which unnecessarily add to the cost of the structure.
Several years ago the Bureau made a start in the rationalization of the design of bridge floors by making an extended mathematical analysis of the simplest case—wide concrete slab simply supported on rigid supports and subjected to wheel loads. This has permitted a somewhat greater accuracy in the design of floors. However, the conditions in most floors do not correspond closely to the assumptions in this case. In order to arrive at a complete solution of the problem it is necessary to make theoretical analyses of the types of floor in use and then verify these analyses by experimenting with actual floors under load.
The cooperative work was begun in 1936. Theoretical analyses have been made of numerous designs of floors, and the results of these studies are now available in bulletins of the University of Illinois. The results of tests on small-scale plaster models and on one full-size bridge floor have also been published in bulletins of the university. Additional tests on full-size floors are now in progress.
The results of this investigation will have direct application to practically all modern highway bridges and to many other structural-design problems and will lead to more satisfactory structures.

INVESTIGATION OF SUPPORTING STRENGTH OF FLEXIBLE CULVERT PIPE IN EARTH EMBANKMENTS
The cooperative culvert investigation by the Bureau and the Iowa Engineering Experiment Station was continued. Observations of pipe deformations and fill settlements were made on culverts that had been constructed during the previous year. A theory of the action of flexible pipes in fills has been developed at the experiment station and comparisons between this theory and the actual behavior of pipe are being made. The purpose of the investigation is to establish, for various conditions of installation, numerical factors that must be considered in determining the strength of pipe required. Because of the large quantity of culvert pipe used in highway work, this investigation will have a direct value in the economical design of highways.
PORTLAND CEMENT
Much interest has recently been aroused among cement technicians regarding the possible effect on durability of adding small quantities of certain substances to portland cement during the manufacturing process. These materials, known as grinding aids, are used primarily to assist in the grinding of the clinker, and it is only recently that attention has been called to the possible effect of such additions on the quality of the cement. Some observers have felt that the beneficial effect of using a blend of portland and natural cement, such as was used in New York and to which reference was made in last year’s report, may have been due to a grinding aid used in the natural cement. They believe that portland cement containing a suitable grinding aid would have produced the same results without the use of natural cement. Others believe that the improvement was due to the addition of the natural cement, as such, and that the same results would have been secured had the natural cement contained no foreign material. The various agencies interested in this problem are now cooperating in a series of laboratory and field investigations in an effort to develop the facts. Experimental roads containing cements with and without grinding aids have been constructed in four States, while in the laboratory tests are under way to determine in just what respects the physical characteristics of portland cement are affected by the presence of such substances.
There is a definite feeling on the part of many engineers that some of the troubles with concrete which have recently occurred may be due, in part at least, to a lack of durability in the cement. These engineers are firmly convinced that the so-called old-fashioned cement, which contained less lime than the average modern cement, produced a more durable concrete. Partly in recognition of this possibility, the cement manufacturers recently proposed an accelerated soundness test for cement known as the autoclave test. This test is supposed to insure cement entirely free from the so-called delayed unsoundness to which some of the concrete-road failures have been attributed. An investigation of this test has been under way in the laboratory for over a year. This work includes the testing of cements now being used in road construction, the place of use of the cement represented by each sample being noted in order that the results of the tests may later be correlated with service behavior.
ANNUAL REPORTS OF THE DEPARTAIENT OF AGRICULTURE, 1939	81
MASONRY CEMENT
The efflorescence that is frequently observed on the surface of masonry walls, while not serious structurally, is objectionable from the standpoint of appearance. A study was begun last year in an effort to determine whether there is a relation between tendency toward efflorescence and the type of cement used, and also whether it is possible to control efflorescence through the use of certain chemicals that preliminary laboratory tests have shown to be effective. A 30-panel brick wall has been erected, using masonry mortars prepared with different brands of cement with and without the addition of the so-called efflorescence-retarding chemicals. Results of this study should be available during the current year.
AGGREGATES
Investigation of the Los Angeles abrasion test and the various procedures for determining soundness of aggregates are being continued. The possibility of modifying the Los Angeles test so that any size material may be tested is being studied. At present only the 1%- to %-inch size can be tested, a disadvantage in the case of materials that are nonuniform in quality. The tests comparing the results of the Los Angeles test with the action of a 10-ton road roller, referred to in last year’s report, have been completed, and a report is being prepared for publication.
CONCRETE
The program of tests begun several years ago, that had for its object the development of a satisfactory laboratory test for rating the efficiency of materials used for curing concrete, was partly completed, and a paper was published describing the procedure as well as reporting the results obtained with a large number of materials.
An extensive series of tests was initiated for the purpose of studying the volume-change characteristics of concrete. Experience in certain States has indicated a marked difference in service behavior of concrete roads that apparently is related in some way to the aggregates used. Failure is usually manifested by excessive expansion of the concrete after a few years’ service. The tests are for the purpose of determining whether the tendency to excessive volume change is due to the nature or grading of the aggregate or to both. In all cases the materials meet the specification requirements now in force so that this study is of fundamental importance.
PAVING BRICK
The need for further information regarding the significance of tests for paving brick resulted in the construction last year of an experimental brick road in Ohio, in which brick from every plant in the State were used. This is a cooperative project, the Ohio State Highway Department, the National Paving Brick Association, and the Bureau participating. A complete series of tests, including many special tests not now used in specifications, is being made by each cooperating agency. The results will be compared later with the behavior of the pavement under traffic.

BITUMINOUS ROAD MATERIALS
As in previous years, investigations have been continued to determine the significant properties of bituminous materials and aggregates for bituminous road surfaces and to correlate these properties with their service behavior. Laboratory tests were made on materials for (1) compliance with given specifications governing the construction of certain roads, (2) standardization of test methods in cooperation with State highway departments and other technical organizations, (3) the modification and development of specification requirements, and (4) the determination of the suitability of new materials or new combinations of materials for use under various conditions. Periodic observations of selected sections of road, in which materials of known characteristics have been used, serve to correlate the results of laboratory tests with the actual service performance of these materials.
Investigations designed to verify accepted theories or to develop additional information on bituminous materials and mixtures are being carried on alone or in cooperation with the State highway departments and committees of technical organizations. Recent cooperative efforts have led to suggested changes in the grades of liquid asphaltic road materials of the medium-curing and rapid-curing types and in the specification requirements for the different grades, that will result in technical improvements.
Laboratory investigations of the physical and chemical properties of asphaltic materials, tars, and emulsions, and the behavior of surfacings containing them must be made continuously for informational purposes. These studies are always necessary because of the development of new sources of supply, changes in refining methods, and the introduction of new paving mixtures.
A very important phase of this work has been the recent laboratory examination of 40 asphalt cements of the 2 grades, 50-60 and 85-100 penetration, from representative refineries using both domestic and foreign crude petroleums. The test data have been assembled in a report for publication. The examination of the materials included not only tests commonly used in standard specifications but also many special tests that have been proposed. The results of this study indicate that the adoption of certain of the proposed tests would restrict the available supply of asphalt to a great degree by eliminating many asphalts that have given satisfactory service under severe traffic and climatic conditions.
Research on the behavior of bituminous materials under laboratory tests designed to produce accelerated weathering have been continued by exposing both the bituminous materials and aggregate containing them to the light, heat, and moisture conditions of a special accelerated weathering device. The possibilities of specifying the required behavior of films of bituminous materials of microscopic thickness are being studied.
Research on bituminous mixtures to determine their probable behavior under actual traffic has continued. Accelerated traffic tests on a small circular track and many of the mechanical strength tests have been employed to study the characteristics of bituminous surfacing mixtures and bituminous stabilized-base courses. Although bituminous materials have been used successfully in stabilized-base
ANNUAL REPORTS OF THE DEPARTMENT OF AGRICULTURE, 19 39 83 construction, more exact information is needed as to the type and quantity of material required for given conditions, methods of incorporating the binder, and the details of laying and compacting the mixture.
Experiments with cotton fabric in highway construction are being continued. .Fabric is being used as reinforcement in bituminous road surfaces, as reinforcement in bituminous ditch linings and spillways, and for the temporary protection of the seeded slopes of cuts and fills. A great deal of experimental work has been done with cotton fabric in bituminous surfacing. Twenty-four States, using fabric furnished by the Department of Agriculture, have reported the construction of 127 projects representing more than 350 miles of fabric-reinforced roads. These include various types of surfaces such as surface treatment, penetration, plant mix, and road mix. Reports are being received on the construction, maintenance requirements, and service behavior. Inspections were made of 81 projects in 15 States and included practically all types of bituminous surfacing in which fabric has been used.
Among these are the four special cooperative experiments constructed in Alabama, North Carolina, South Carolina, and Tennessee, which have received and are receiving more detailed study than is usually given to routine projects. These, as well as the other test sections, will be observed as long as required to establish definitely the economic worth of fabric thus used.
The laboratory study of asphalt cements that has been conducted cooperatively with the Minnesota State Highway Department and the University of Minnesota has been completed and a report prepared for publication.
SUBGRADE INVESTIGATIONS
Soil studies were continued along the lines described in former reports. They consisted of studies of laboratory test methods, studies of low-cost road surfaces placed on small tracks and subjected to destructive forces similar to those of traffic and nature, observations of experimental roads and embankments constructed in cooperation with the various State highway departments, and surveys of roads constructed of low-cost materials.
The Bureau’s tests for determining the grading, plasticity, and related properties of soil indicative of the stability have been adopted as standard methods of test by the American Association of State Highway Officials and the American Society for Testing Materials. The demand from other laboratories for standard samples for use in making check tests to improve their technique and apparatus has continued.
Investigation was made of new apparatus for determining particlesize distribution of fine-grain soils. The apparatus utilizes a new principle of dispersion that eliminates objectionable features of the mechanical method now in use. Photomicrographic studies of the structure and formation of soil in its natural state and the effect of moisture content and admixtures on the soil fabric were begun. The research on the microchemical analysis of soil solutions reported last year has progressed and quantitative chemical analyses by spectrographic methods has received consideration.

BUREAU OF PUBLIC ROADS
A world-wide survey of soil-testing apparatus made in cooperation with the Highway Research Board contributed materially to the Bureau’s progress in the soil-testing field.
Tests for the control of embankment and stabilized-soil road construction attained the status of standard methods, and correlation of the compaction characteristics with the structural properties of soil was begun. Satisfactory devices were developed for making direct shear and stabilometer tests and simplified procedures were developed for determining permeability and capillarity which disclose drainage characteristics and the possibility of frost heave of soil.
In. the realm of soil mechanics, analyses utilizing the theories of elasticity and of plastic equilibrium were simplified to facilitate their practical application to the problems of highway construction. Reports of this work previously published were supplemented by one on the design of abutments and retaining walls and another on the considerations involved in the construction of embankments on soft undersoils. To facilitate the correlation of theory, field observations and laboratory-test data in relation to such problems, the work is to be extended to include studies of stress distribution by means of photoelastic equipment and models constructed with differently colored layers of earth.
To meet the urgent need for information on the moot question of the relative effect of surface tension exerted externally, and of colloidal phenomena acting within, on volume change, compressibility, com-pactibility, and stability of stressed earth masses at different moisture contents, the performance of soil and water mixtures was compared with that of the same soil mixed with other liquids that have greater and less surface tensions than water. Studies of the permeability of soil-bentonite mixtures made in cooperation with the United States Forest Service were continued.
In the field of soil stabilization, efforts were devoted to studies of special local materials, construction methods, tests for bituminous-and cement-stabilized soil, and the preparation of specifications.
Among the local, materials studied with special reference to their suitability for use in base courses were the volcanic ash deposits of Arizona, certain topsoils in the Southern States, and crusher-run aggregates.
The experimental embankments, referred to in last year’s report, have been constructed in Ohio and Indiana, and observations are being made of the performance of sections constructed by different methods.
. Comparison of data furnished by the circular track tests, mentioned in last year’s report, with road performance has demonstrated the value of the tests for determining quickly and at relatively small expense the serviceability of road-building 'materials. These track tests have been found to be an excellent tool in determining which laboratory tests, out of the many suggested, disclose most accurately the information required in. the construction of stabilized-soil roads. Among the materials investigated by track tests are various mixtures of. sand-clay, sand-clay-gravel, and crusher-run aggregates, with and without treatment with deliquescent chemicals, and soils of different types with admixtures of portland cement and the various types of bituminous binders.
