Influence of the Cement Stabilized Macadam Base Modulus Change on the Mechanical Properties of Asphalt Pavement under Heavy Load

摘要

The elastic plastic theory and finite element software are applied to analyze the stress of semi-rigid asphalt pavement structure of highway under different wheel load. The influences of modulus variation of cement stabilized macadam base on tensile stress at the bottom of layer, shear stress of surface layer and the surface deflection of the pavement structure under different wheel pressure are drawn for reference.
