AASHO ROAD TEST PRINCIPAL RELATIONSHIP - PERFORMANCE WITH STRESS, RIGID PAVEMENTS

THIS PAPER PRESENTS A SUMMARY OF THE STRAIN MEASUREMENTS TAKEN ON THE PORTLAND CEMENT PAVEMENTS AT THE AASHO ROAD TEST. STRESS CONVERSIONS AND ANALYSES OF THESE DATA ARE DISCUSSED. THE EDGE STRESSES MEASURED UNDER ROUTINE TRAFFIC ON THE TEST LOOPS AND THE CRITICAL STRESSES MEASURED UNDER A SIMULATED LOAD ON THE NONTRAFFIC LOOP ARE COMPARED WITH THE ROAD TEST PERFORMANCE EQUATIONS. ADDITIONAL RESEARCH AND ANALYSES ARE SUGGESTED. THE LOAD STRESSES IN THE RIGID PAVEMENTS AT THE AASHO ROAD TEST WERE HIGHLY CORRELATED WITH PERFORMANCE. THE CRITICAL LOAD STRESSES MEASURED UNDER DYNAMIC LOAD ON A SPECIAL SET OF PAVEMENTS PROVIDED THE HIGHEST CORRELATION WITH PAVEMENT PERFORMANCE. A DIFFERENT CORRELATION EXISTS FOR SINGLE-AXLE LOADS THAN FOR TANDEM-AXLE LOADS. THIS MAY BE DUE TO THE LOCATION OF CRITICAL LOAD STRESSES UNDER THE TANDEM AXLES. FURTHER ANALYSIS OF THE ROAD TEST BASIC PERFORMANCE DATA AND STRESS DATA IS DEFINITELY WARRANTED. SUCH AN ANALYSIS WOULD ALLOW SUMMARIZATION OF THE DIFFERENCES BETWEEN PERFORMANCE PREDICTED FROM STRESS AND OBSERVED PERFORMANCE. (THE PRESENT ANALYSIS COMPARES PREDICTED PERFORMANCE WITH STRESS). ADDITIONAL EXPERIMENTS SHOULD BE INITIATED TO STUDY THESE STRESS-PERFORMANCE RELATIONSHIPS FOR OTHER CONCRETE PAVEMENTS HAVING DIFFERENT MATERIALS AND THUS DIFFERENT PHYSICAL PROPERTIES. /AUTHOR/
