Low-Temperature, Anti-Cracking Performance of Superpave Asphalt Mixture
The mixture ratio design of asphalt mixture is based on the material design system of Superpave asphalt mixture. The purpose of using the MTS fatigue testing machine to do flexural test is to test its low-temperature, anti-cracking performance. At the same time, the performance indexes of asphalt mixture are compared with the performance indicators, which are determined by the Marshall compaction method. The results show that the optimum asphalt content designed by the material design system of Superpave asphalt mixture has reduced. The low-temperature, anti-cracking performance of asphalt mixture that is determined by Superpave asphalt mixture design system is better. The flexural strength RB and the maximum bending εB of the material design system of Superpave asphalt mixture is slightly less than that which is designed by Marshall Compaction method.
