  • In order to correctly predict the permanent deformation of asphalt pavement, nonlinear viscoelastic finite element method was studied, the finite element method of nonlinear viscoelasticity for generalized Maxwell model was deduced, a nonlinear viscoelastic-elastoplastic constitutive model of permanent deformation for asphalt pavementhen was set up, and the permanent deformation of asphalt pavement was analyzed depending on its material properties, such as elasticity, nonlinear elasticity, plasticity, viscoelasticity and nonlinear viscoelasticity, etc., the permanent deformation of asphalt pavement was simulated by using the model, SHRP and SWK/UN experiment, and the numerical results were compared.Comparison result shows that their relative error are 6.567% and 6.069% respectively, the model is effective.
