Abstract
This Paper aims to analyze the influence of the short-term aging on the physical and rheological characteristics of asphalt containing a combination of crumb rubber and rice husk ash at high temperature. To simulate the aging on a short term in the laboratory, the rolling thin film oven test was conducted. Obtained results indicated that adding CR and RA had significant positive effect on the aging resistance of asphalt binder through increasing penetration aging ratio (PAR) values. Nevertheless, adding CR and RA reduced softening point increment (SPI), viscosity aging index (VAI), as well as the rutting factor aging index (AIOR).
