Abstract: In high grade pavement structure, Permanent deformation of rutting is one of the main destruction. In this paper, the mechanical analysis of high grade road surface is carried out by means of the viscoelastic model. The conclusion is drawn by the comparison of the Maxwell、Kelvin、Van Der Poo and Burgers vis-coelastic mechanics model. It is necessary to considering material nonlinear elastic, viscoelastic and plastic and other basic characteristics, the eventual establishment of reasonable permanent deformation tests of mechanical model and permanent deformation analysis method in the analysis of permanent deformation of asphalt pavement.
