THE EFFECTIVENESS OF SAND ASPHALT BINDER COURSE IN REDUCING STRIPPING IN BITUMINOUS PAVEMENTS

THIS REPORT IS CONCERNED WITH A SURVEY OF ASPHALT PAVE- MENTS WHICH WERE EXAMINED TO DETERMINE THE EFFECTIVENESS OF THREE DIFFERENT TYPES OF TREATMENTS OF THE GRANULAR BASE OF PAVEMENTS, IN THE PREVENTION OF ASPHALT STRIPPING. TWO OF THESE WERE FOUND TO BE UNSUITABLE DUE TO DIFFICULTIES IN CONSTRUCTION. THESE WERE, PRIMING WITH RAPID-CURE CUT- BACK ASPHALT (RC-30), AND PRIMING WITH SLOW-SETTING EMULSION (SS-1H). THE THIRD TREATMENT CONSISTED OF THE PLACING OF A 3/4 IN. COURSE OF HOT-MIX SAND ASPHALT DIRECTLY ON THE GRANULAR BASE. AN EVALUATION OF THE EFFECTIVENESS OF THE HOT-MIX SAND ASPHALT COURSE WAS MADE AND THE RESULTS OF THIS STUDY SHOWED THAT HOT-MIX SAND ASPHALT SIGNIFICANTLY REDUCES THE INCIDENCE OF STRIPPING. IT WAS ALSO FOUND THAT STRIPPING STILL OCCURS TO A LESSER DEGREE, IT IS CONFINED LARGELY TO THE HOT-MIX SAND ASPHALT COURSE.
