Abstract


Due to the huge difference of material properties, the bonding condition between asphalt layer and concrete leveling course on concrete bridge deck is very complex, which can directly affect the stress distribution of structure layers. Aiming at the common hollow plate girder bridge, a study was conducted to analyze the mechanics response of structure layers under different contact conditions, by using the finite element analysis software ANSYS. The results show that the stress of structure layers is significantly affected by the bonding condition between asphalt layer and concrete leveling course, and the complete continuous contact condition is not reasonable in the design of deck pavement structure; for four kinds of contact states, the stress of structure layers is optimal under complete bonding state, and when the interlayer bonding is insufficient, the contact state between structure layers is much closer to the hypothetical binding state.
