The AASHO Road Test Report 5: Pavement Research; By The Highway Research Board Of The NAS-NRC Division Of Engineering And Industrial Research Special Report 61E, Publication No. 954

"The AASHO Road Test was conceived and sponsored by the American Association of State Highway Officials as a study of the performance of pavement and bridge structures of known characteristics under moving loads of known magnitude and frequency. It was administered by the Highway Research Board of the National Academy of Science - National Research Council, and was considerably larger and more comprehensive than any previous highway research study. This is the fifth of a series of major reports on the AASHO Road Test. The first four reports are "History and Description of Project", "Materials and Construction", "Traffic Operations and Pavement Maintenance", and "Bridge Research". Additional reports in the series include "Special Studies" and "Final Summary". This report is a comprehensive summarization of all research related to the test pavements. It describes briefly the experiments and experiment designs, test traffic, measurement programs and data collection procedures, methods of analysis, and the results of the analyses. It is presented in three major parts. The first is general in nature, describing the back ground and objectives of the research, facilities and methods of operation employed, and the "present serviceability" concept of pavement performance evaluation. The second and third parts describe the flexible and rigid pavement experimental designs and research and report the findings." [from preface]
