DISTRIBUTION OF ASPHALT CEMENT IN ASPHALT MIXES WITH AND WITHOUT FILLERS

USING MIXES CONTAINING SYNTHETIC AGGREGATES /STEEL AND GLASS BALLS, ETC./ THE AUTHOR SHOWS THAT THE PERCENT OF ASPHALT OF A SINGLE SIZE FRACTION IS A FUNCTION OF THE MEAN GRAIN DIAMETER AND A SPECIFIC CHARACTERIZING FACTOR FOR EACH MATERIAL IN MIXES CONTAINING NO FILLER. THE CHARACTERIZING FACTOR IS DEPENDENT ON MATERIAL USED AND REFLECTS INFLUENCE OF GRAIN SHAPE AND SURFACE STRUCTURE. THE INFLUENCE OF SPECIFIC GRAVITY IS CONFIRMED USING MIXES CONTAINING AGGREGATES OF WIDELY DIFFERING DENSITIES. FROM THE FORMULA DERIVED, FURTHER RESEARCH SHOWS THAT THE FUNCTION IS VALID FOR MIXES CONTAINING FILLERS REGARDLESS TO WHATEVER COARSE TEXTURED FRACTION THE FILLER MAY BE ADDED. FURTHER STUDIES ARE REQUIRED TO DETERMINE THE SPECIFIC CHARACTERIZING FACTOR FOR OTHER TYPES OF AGGREGATES. /NAPA/
