Research on Dynamic Performance and Road Performance of Dense-Gradation Asphalt Mixture

摘要

The scientific construction of technical specifications for construction of highway asphalt pavement puts forward higher requirements on the performance and grade of construction materials such as asphalt and other materials. The performance of asphalt mixture has an important impact on the quality of pavement engineering. In this paper, we research and analyze different whetstones and different gradations of dense-graded asphalt mixture by applying computer technology and the Marshall test. the results of the Marshall test show that the properties of dense-graded asphalt mixture are within the scope of the index under a reasonable gradation, and dynamic stability and residual stability meet the specifications, and the dynamic performance and road performance of dense-mixed materials meet the requirements by the comprehensive testing.
