Stress Analysis of Asphalt Concrete Deck Pavement on Steel Bridge based on Burgers Model and interlayer contact

摘要

A three-dimensional finite element steel bridge and its deck pavement were established by ANSYS software to simulate the influence of different model and bonding failure between adjacent layers on stress values of asphalt concrete deck pavement. The stress values of asphalt concrete deck pavement were calculated and analyzed with consideration of the characteristic of asphalt concrete and interlayer bonding condition. 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 computed and analyzed. At the same time, the influence of the disengaging area between the lower layer of asphalt concrete and the waterproof layer on the stress values of asphalt concrete deck pavement was calculated and analyzed.
