Research on Designing Optimum Asphalt Aggregate Ratio of Asphalt Mixture by Mechanical Index Method

Abstract:

The article designed optimum asphalt aggregate ratio of asphalt mixture by mechanical index method, the purpose of the mechanical index method is that the bond strength and internal friction angle of asphalt mixture can reach a best balance, the shear stress reaches the maximum, so the results have a good effect for preventing rut. The research indicated that the surface layer performance of asphalt mixture which designed by the mechanical index method is better than by the traditional Marshall method, so the mechanical index method is a simple and effective method.
