Stress Analysis for Asphalt Concrete Deck Pavement with Considering Viscoelasticity of Asphalt Concrete and Interlayer Bonding Condition

Xuntao Wang, Jianhu Feng, Hu Wang


A three-dimensional finite element box girder deck pavement model was established by ANSYS software to simulate the effect of thickness of asphalt concrete and disengaging area existing between adjacent layers on the stress of deck pavement with considering the viscoelasticity of asphalt concrete and interlayer bonding condition. The suitable thickness of the upper layer of asphalt concrete was advised, and the influence of the disengaging area between the upper layer and lower layer of asphalt concrete on the stress values of asphalt concrete deck pavement was analyzed.
