A finite element model of pavement under the complex moving wheel load was established in this study. Subsequently, viscoelastic behavior simulation of pavement had been conducted, and the influence of wheel set and axle set on pavement response had been analyzed. Results indicate that the strain-hardening formulation is more suitable for the creep rule of asphalt mixture in the proposed model. Under the repeated action of moving wheel load, the distribution of stress in the pavement tends to be uniform, and the intermediate pavement layer is subjected to a large Tresca stress. Under the same tire operating condition, the single-wheel set makes the same contribution to the permanent deformation of pavement with the dual-wheel set, and the damage effect of daul-axle set on pavement is more significant than that of single-axle set.
