Abstract: In order to study the asphalt pavement under the action of ｌｏａｄ analysis, the variations of all the mechanical parameters of BISAR3.0 and three finite element method is used, to the  asphalt surface stress distribution are analyzed. Results show that under different conditions of   ｌｏａｄ and the contact between the layers, the vehicle ｌｏａｄ under the action of random, under vertical dynamic ｌｏａｄ, under horizontal ｌｏａｄ, pavement parameters reflect some regular changes.

Keywords: BISAR3.0, three-dimensional finite element, interlayer contact, mechanical respons.
