Mechanical Response Analysis of Different Asphalt Pavement Structure under Heavy Load Traffic Effects

Abstract

For Yingkou Dashiqiao Xiushui line (Yangfang-Gaokan) test road paving concrete actual situation, the finite element mechanics response analysis of four types of heavy traffic asphalt pavement typical structure under heavy load conditions is analyzed in this paper. The results show that road surface is the most unfavorable position of the asphalt pavement structure under the overloading traffic conditions; Overloading can make the surface layer and base bending tensile stress, tensile strain greatly increased; Overloading will lead to the interlayer shear stress increased dramatically, and shear stress mainly acts on the surface area. The results can provide numerical analysis and theoretical basis for heavy traffic asphalt pavement structure design in the future.
