STRIPPING IN HOT-MIXED SAND ASPHALT MIXTURES

FUNDAMENTAL CONCEPTS ARE REVIEWED RELATING TO ADHESION AND THE STRIPPING PHENOMENA IN BITUMINOUS MIXTURES. SATURATED SAND-ASPHALT MIXTURES ARE SUBJECTED TO REPEATED AXIAL AND HYDROSTATIC PRESSURE AND THE REDUCTION IN THE UNCONFINED COMPRESSIVE STRENGTH DUE TO THE EFFECT OF WATER IS INVESTIGATED. THE STUDY SHOWS THE IMPROVED CHARACTERISTICS OF THE SAND-ASPHALT MIXTURE CONTAINING AN ANTISTRIPPING AGENT AND THE MIXTURE WITH LESS AIR VOIDS. IT IS POINTED OUT THAT REDUCTION IN VOID CONTENT EITHER BY COMPACTION OR BY A CHANGE IN MIXTURE COMPOSITION CAN BE USED AS A PREVENTIVE MEASURE IN THE FIELD. THE STUDY DEMONSTRATES AN IMPROVED TEST AND PRECONDITIONING PROCEDURE FOR THE INVESTIGATION OF THE EFFECT OF WATER ON BITUMINOUS MIXTURES. /BPR/
