Abstract

Three samples of fresh bitumen of 80/100 pen, 60/70, and PG70 were tested to determine whether pressure Aging Vessel (PAV) test for 25 hours would provide similar results to the protocol of Strategic Highway Research program (SHRP) coupled aging procedure, Rolling Thin Film Oven Test (RTFOT) and PAV. Bitumen conducted by both procedures (a) PAV only for 5 and 25 hours (b) RTFOT only and RTFOT+PAV 20 hours. Two procedures compared on the basis of the bitumen conventional properties, penetration at 25ºC, softening point, and viscosity at 135ºC tests. This study was intended to simulate the aging process by using Rolling Thin Film Oven Test to compare with Pressure Aging Vessel. The results show that there is equivalence between the effects of using RTFOT and PAV for 5 h at temperature of 100ºC under pressure 2.1MPa for the unmodified bitumen 80/100 and 60/70 penetration. It appears that the modified bitumen binder PG70 has significant difference in the results.
