ANNUAL REPORT-STRIPPING IN HOT-MIXED SAND-ASPHALT MIXTURES

IN THIS REPORT AN ATTEMPT IS MADE TO SEARCH FOR THE CAUSES OF STRIPPING OBSERVED IN HOT-MIX SAND-ASPHALT PAVING MIXTURES, AND TO DEVELOP A REALISTIC HYPOTHESIS AND TESTING PRODECURE FOR EVALUATION OF STRIPPING CHARACTERISTICS IN THESE MIXTURES. THE INVESTIGATION DESCRIBES SPECIFIC ROAD FAILURES RELATED TO THE STRIPPING PHENOMENA AND THE SHORTCOMINGS OF STANDARD LABORATORY TESTS AS APPLIED TO THESE PROBLEMS. TO DUPLICATE FIELD CONDITIONS, A DYNAMIC PRECONDITIONING METHOD WAS DEVISED IN WHICH SAMPLES WERE SUBJECTED TO SPECIFIC NUMBER OF LOAD REPETITIONS PRIOR TO TESTING FOR COMPRESSIVE STRENGTH TO BE DRASTICALLY REDUCED BY DYNAMIC PRECONDITIONING. THE CREEP REPONSES WERE LESS CONSISTENT DUE TO DIFFERENCES IN THE STRAIN HISTORY OF CREEP SAMPLES. FURTHER INVESTIGATIONS ARE NEEDED TO DEVELOP ACCEPTABLE RHEOLOGICAL MODELS FOR DESCRIBING STRIPPING PHENOMENA. /AUTHOR/
