A kind of composite modified asphalt with high elasticity was prepared by SBS and high elasticity agent, and the asphalt mixture with easy compactness was applied. The high temperature, low temperature, water stability and fatigue properties of the mixture were evaluated by laboratory tests. The results show that the optimum content of high elasticity agent is about 6% for SBS modified asphalt. The pavement performance of the high-elasticity modified asphalt compacting mixture was improved to a certain extent. Compared with SBS modified asphalt SMA-13, the dynamic stability was increased by 13.5%. The water stability, low temperature crack resistance and fatigue resistance increased by 10.4%, 59.3% and 173%.
