Abstract：ABAQUS software was adopted to establish the model of semirigid pavement structure with uniaxial twowheel load mode and each tire load simplified to five mobile nonuniform load with different stress, length and width. Compiling Dload and Utracload subroutines by Fortran program, the vertical, horizontal and transverse loads were applied. The relationship between transverse stress and pavement shear stress was analyzed. The results show that the pavement surface shear stress distribution has significant relationship with transverse stress. When the lateral friction coefficient is increased, the positive shear stress is decreased with increased negative shear stress. The location of the maximum positive shear stress is at the tire edges of both sides. The negative shear stress at intermediate load belt is increased gradually and over tire edge shear stress, and the maximum negative shear stress transfers from the edge to the middle. The lateral friction coefficient is increased linearly with different point shear stress at different asphalt pavement layer. The influence of lateral friction coefficient on surface shear stress is most obvious, while in other layers of asphalt pavement, the influence on shear stress is decreased with the increasing of depth.
