STUDY OF MINERAL FILLERS FOR SHEET-ASPHALT MIXTURES

THREE FILLERS, FLY ASH, HYDRATED LIME, AND QUARRY DUST, WERE EVALUATED ON THE BASIS OF SIMPLE BEAM TESTS THAT REFLECT THE VISCOUS RESISTANCE OF THE MIX. INDIAN STANDARD SAND AND ASPHALT OF STANDARD SPECIFICATION WERE USED. THE 10-IN. LONG TEST SPECIMEN WAS SUPPORTED ON MILD-STEEL ROLLERS 20 CM (8 IN.) APART AND ALLOWED TO DEFLECT UNDER ITS OWN WEIGHT ONLY. THE DEFLECTION WAS MEASURED AT DIFFERENT TIME INTERVALS UNTIL THE SPECIMENS FAILED. A GENERALIZED FORM OF CREEP LAW WAS USED IN ESTIMATION OF THE RESISTANCE OFFERED BY THE DIFFERENT MIXES TO DEFORMATION. FOR A GIVEN PERCENTAGE OF BINDER WITH INCREASING CONCENTRATION OF FILLER, THE RESULTING MIX BECOMES STIFF WITH DECREASING DEFORMATION CHARACTERISTICS IN THE CREEP CURVE. THE OPTIMUM F-A RATIO IS THAT AT WHICH CREEP CONSTANTS ARE MINIMUM. A MEASURE OF THE GREATEST RESISTANCE IS DESCRIBED, AND FLY ASH IS RATED HIGHEST.
