HamptonVIRGINIAPOLYTECHNICINSTITUTE ANDSTATEUNIVERSITYB lacksburg, VAResearch sponsored by the American Association of State Highway and Transportation Officials in cooperation with the Federal Highway AdministrationNATIONAL COOPERATIVE HIGHWAYRESEARCH PROGRAMS ystematic, well-designed research provides the most effectiveapproach to the solution of many problems facing highwayadministrators and engineers. Often, highway problems are of localinterest and can best be studied by highway departments individuallyor in cooperation with their state universities and others. However, theaccelerating growth of highway transportation develops increasinglycomplex problems of wide interest to highway authorities.

7 Theseproblems are best studied through a coordinated program ofcooperative recognition of these needs, the highway administrators of theAmerican Association of State Highway and Transportation Officialsinitiated in 1962 an objective national highway research programemploying modern scientific techniques. This program is supported ona continuing basis by funds from participating member states of theAssociation and it receives the full cooperation and support of theFederal Highway Administration, United States Department Transportation Research Board of the National Academies wasrequested by the Association to administer the research programbecause of the Board s recognized objectivity and understanding ofmodern research practices.

8 The Board is uniquely suited for thispurpose as it maintains an extensive committee structure from whichauthorities on any highway transportation subject may be drawn; itpossesses avenues of communications and cooperation with federal,state and local governmental agencies, universities, and industry; itsrelationship to the National Research Council is an insurance ofobjectivity; it maintains a full-time research correlation staff ofspecialists in highway transportation matters to bring the findings ofresearch directly to those who are in a position to use program is developed on the basis of research needs identifiedby chief administrators of the highway and transportation departmentsand by committees of AASHTO.

9 Each year, specific areas of researchneeds to be included in the program are proposed to the NationalResearch Council and the Board by the American Association of StateHighway and Transportation Officials. Research projects to fulfill theseneeds are defined by the Board, and qualified research agencies areselected from those that have submitted proposals. Administration andsurveillance of research contracts are the responsibilities of the NationalResearch Council and the Transportation Research needs for highway research are many, and the NationalCooperative Highway Research Program can make significantcontributions to the solution of highway transportation problems ofmutual concern to many responsible groups.
