The influencing factors of asphalt pavement permanent deformation based on numerical simulation

Using finite element software ABAQUS,this paper established finite element model of asphalt pavement,respectively made quantitatively analysis on influence factors of asphalt pavement permanent deformation from surface layer modulus,surface layer thickness,temperature,axial load and other aspects,the results showed that,treatment of asphalt pavement rutting problems,not only from the material,but also should comprehensive considered combining with pavement structure parameters.
