Analysis of the vehicle–pavement couple system was mainly based on the linear elastic model in frequency domain considering pavement roughness. The nonlinear dynamic numerical model for the vehicle–pavement coupled system was established using the finite-element method. Using the model, the deformation characteristics of asphalt concrete pavement were studied under the conditions of different pavement roughnesses, different vehicle speeds, different vehicle loads, and different sub grade strengths. When the pavement roughness was worse and the vibration deformation of the pavement was larger, the max deformation of the C-level pavement roughness was 1.31 times that of the A-level pavement roughness. With increased vehicle speed, the deformation of pavement was smaller, but the trend was not obvious. The deformation of pavement increased obviously for overload, and the ratio of the overload reached by 100%, the ratio of deformation increased by 50% to 109%. The deformation of pavement increased obviously for the subgrade strength reduction, the subgrade strength was reduced by 28%, and the deformation of the pavement increased by about 15%.
