This research carried out the NO2 degradation performance and asphalt pavement performance of SBS modified asphalt with different content (0%, 1%, 2%, 5%, 10%) of nano-TiO2, and the impact of cationic surfactant were evaluated as well. The nano-TiO2 modified asphalt was prepared for Dynamic Shear Rheometer (DSR) test, Bending Beam Rheometer (BBR) test, Rolling Thin Film Oven Test (RTFOT) and Pressure Aging Vessel (PAV) test. And the high temperature performance, low temperature performance and aging properties were evaluated. Results show that the nano-TiO2 increased the rutting resistance of ...
