Abstract A box girder bridge was simulated by ANSYS software, where the interlaminar relation of the bridge deck pavement was assumed to be frictionally sliding rather than continuous. Stresses of the asphalt concrete pavement were calculated when various disengaging areas between the layers appeared in the load region. Results showed that the size of the disengaging area in the load region had a significant influence on the stresses of the asphalt concrete. The position where the disengaging area appeared obviously changed the stresses of the asphalt concrete; when the disengaging area appeared under the load region, the horizontal load increased the shear stresses of the asphalt concrete. The relative positions of the disengaging area and the load region also influenced the stresses of the asphalt concrete.
