摘要：

The model of the multi-layer asphalt pavements is built with the finite element software ANSYS according to the elastic layer system theory. Based on the model, the shear stress distribution along the depth of the asphalt layer in asphalt pavements is calculated. The shear stress distribution changing rules of the asphalt layer as thickness of surface, modulus of base or thickness of base change are found by calculating lots of structural compositions. Based on these rules a shear stress curve functional equation along the depth of the asphalt layer is obtained by modifying the probability density function of the Gamma Distribution. Software used calculating shear stress and pavement rut is programmed according to the function above and the function of pavement rut evaluation.
