Abstract: SBS-modified asphalt (SMA) processes fine performance at high or low temperature, but it shows poor stability at high temperature, which leads to segregation. Addition of inorganic super fine powder can expect to further enhance the elasticity at high temperature. These improved parameters can lead to an improvement on anti-oxidation and anti-rutting. In this work, different inorganic super fine powders such as nano- montmorillonite, nano-CaCO3, and microscale flyash were utilized to improve the performance of SBS modified asphalt, and their reinforced machnisms were investigated.
