Article Preview

Graded broken stone materials show cross-anisotropic behavior, but now most pavement structure analysis are based on assuming pavement structure to be isotropic layered system. In order to accurately evaluate pavement responses based on cross-anisotropy utilizing graded broken stone as sub-base materials, the influences of sub-base thickness, horizontal modulus and breaking force on the stress in pavements are studied by using the three-dimensional finite element software ABAQUS. The results show that the shear stress of the pavement decreases with the increasing of the sub-base thickness or the horizontal resilient modulus but the shear stress of the pavement increases obviously with the increasing of braking forces.
