Research On Technical Performance Of Anti-rutting Additive Modified Asphalt Mixture

The rutting of asphalt pavement has become the the major destroy phenomenon,on the base of the solving methods inside and outside of this problem,as the Anti-rutting Additive being modifier,by means of analyzing the performance of the pavement and mechanism of the Anti-rutting Additive modified asphalt mixture.From the viewpoint on performance of road asphalt,the experimental results show that the Anti-rutting Additive can obviously improved the high temperature stability of the asphalt mixture,meanwhile,it can enhance other performances of the asphalt mixture,such as water stability,low temperature ability and durability etc.In this paper,by the research of the effect and enhancing the anti-rutting additive to ordinary asphalt SMA,tests results proveds that the Anti-rutting Additive is a good additive which can improve the SMA performance effectively. the study results of the paper lay a foundation for research,development and application of the Anti-rutting Additive modified asphalt mixture.According to experimentalts results,this paper studys and discussed the Anti-rutting Additive interaction mechanism,and bring forward the Anti-rutting Additive's double improvementing effection to asphalt and aggregate,and give two kinds of the Anti-rutting Additive's double improvement proporty by calculating.According to the way of Mathematical fitting,theoretical optimum dosage interval about the Anti-rutting Additive is given by calculating method.And make 70°C"s high temperature rutting test,for the Anti-r utting Additive technical indicators for the application of the requirements.
