Analysis of Shear Failure of Asphalt Pavement under Horizontal Force

Abstract


The finite element method is used to analyze the shear stress distribution of the pavement structure under vertical load and both vertical and horizontal load. The results show that the distribution coefficient of transverse force affects the distribution of shear stress with depth; The maximum shear stress increases with the increase of the lateral force coefficient, and the two have a linear relationship. When the horizontal force is considered, the shear stress of the asphalt surface layer increases and the peak value moves upward, which may cause rutting, displacement and swelling of the asphalt pavement. It is necessary to incorporate the horizontal force into the structural design index system.
