PRE-EVALUATION OF PAVEMENT MATERIALS FOR SKID-RESISTANCE A REVIEW OF U. S. TECHNIQUES

THIS PAPER IS ESSENTIALLY A REVIEW OF EXISTING METHODS, USED IN THE LABORATORY, FOR STUDYING PAVEMENT MATERIALS AS RELATED TO THEIR SKID-RESISTANT QUALITIES. IT CONSISTS OF DESCRIPTIONS OF TEST EQUIPMENT AND TESTING TECHNIQUES ALONG WITH EXAMPLES OF DATA. IT REPORTS THAT THE LABORATORY TESTS HAVE GENERALLY DEVELOPED AROUND TWO EVALUATION METHODS. ONE IS TO STUDY COMPACTED PAVEMENT MIXTURES; THE OTHER IS TO TEST AGGREGATE PARTICLES OR STONE CHUNKS. BOTH TYPES OF METHODS SEEM TO BE USEFUL IN EVALUATING PAVEMENT MATERIALS PRIOR TO THEIR USE. THE METHODS REPORTED, HOWEVER, DO NOT HAVE WIDESPREAD USE AND ARE NOT ENTIRELY ALIKE. PROBABLY THE PORTLAND CEMENT ASSOCIATION AND THE TENNESSEE HIGHWAY RESEARCH PROGRAM EQUIPMENT HAVE THE GREATEST SIMILARITY, BUT TEST PROCEDURES ARE DIFFERENT. THERE ARE SEVERAL NEW METHODS THAT ARE BEING CONSTRUCTED THAT INCLUDE DESIGN IDEAS FROM OLDER METHODS. ALONG WITH THE MECHANIZED LABORATORY TEST METHODS, INFORMATION ON SUPPLEMENTAL PRE-EVALUATION TOOLS IS REPORTED, INCLUDING PROCEDURES FOR STUDYING THE INFLUENCE ON SKID RESISTANCE OF SAND-SIZE SILICEOUS PARTICLES, MINERAL CONTENTS OF AGGREGATES, AND PAVEMENT PERMEABILITY. IT IS CONCLUDED THAT THE PRE-EVALUATION OF MATERIALS IS A PRACTICAL APPROACH TO OBTAINING BETTER SKID-RESISTANT PAVEMENTS, BUT ADDITIONAL WORK IS NEEDED TO RELATE LABORATORY RESULTS TO FIELD PERFORMANCE. /AUTHOR/
