Superpave Design and Performance Evaluation of Gneiss Based Asphalt Mixture
Superpave method gets widely applied in road construction in China due to its better pavement performance compared to Marshall method.The rapid road construction has consumed lots of high class aggregate such as limestone and basalt.Research on the application of low grade aggregate such as gneiss in pavement is of great importance.In this research,Superpave design and performance evaluation of gneiss based asphalt mixture were conducted.Results showed that gneiss based asphalt mixture obtained good performance by means of superpave method and by properly controlling composite styles of raw materials.
