Abstract：In the field of bridge engineering，the mechanical properties of the pavement layer are one of the key fac⁃ tors to ensure the safety and durability of bridge structures. Based on the study of GA-10+ high elastic SMA-10 composite pavement，this paper constructs the“steel bridge deck-pavement”3D solid model by ABAQUS，simu⁃ lates the interaction between the steel bridge deck and the GA-10+SMA-10 composite pavement，and carries on the structural mechanical analysis. By analyzing the tensile，mechanical properties of GA-10+SMA-10 composite pavement under the influence of different wheel load position in the transverse and longitudinal direction of the bridge. The maximum displacement of the top of the pavement layer and the shear stress are determined to deter⁃ mine the most unfavorable load position，and the results show that：（1）The most unfavorable load position is the middle of the adjacent trapezoidal stiffener and the middle of the adjacent diaphragm；（2）GA-10+SMA-10 compos⁃ ite pavement has strong shear resistance and deformation resistance；（3）The maximum displacement of GA-10+ SMA-10 composite pavement under the most adverse load condition has been effectively controlled，and this struc⁃ ture has good stability and durability.
