Abstract

One purpose of modified asphalt is to improve its high-temperature resistance to ruttings. This paper investigated the main influencing factors and the nonlinear prediction model of the anti-rutting performance index anti-rutting factor of crumb powder and SBS double modified asphalt. Meanwhile, a dynamic shear rheometer was adopted to test the anti-rutting factor G∗/sinδ of double modified asphalt prepared with two types of asphalt and different SBS and crumb rubber mixing contents at four different temperatures (70℃, 76℃, 82℃, and 88 ℃), with a nonlinear model for the anti-rutting factor built. The results show that the modifier mixing content factor of composite modified asphalt is exponentially related to the modifier mixing content, and the temperature factor of the rheometer test is also exponentially related to temperature.
