Abstract: The 3D FEM is employed to analyze the mechanical response of asphalt pavement on bridge decks under non-uniform distribution loading with different interlayer contact conditions. The results show that it is necessary to consider the non-uniform distribution load in the material and structure design of the asphalt pavement on bridge decks. The change of the interlay contact conditions will lead the stress and strain in asphalt layer to increase and redistribute. It will cause more severe distress in asphalt pavement.
