A 3D finite element model has been presented to investigate the dynamic response of transition zone between the bridge and highway. The traffic load is regarded as a periodically moving load and has been implemented into ABAQUS code as a user subroutine VDLOAD. The dynamic stress
displacement and pavement cracking in transition zone under one cycle or some cycles are closely studied by using ABAQUS standard and explicit module. It can be concluded that the accumulation of the bridge-approach settlement makes pavement cracking under traffic loading; and the pavement will fracture completely as the cracking runs through the pavement structure. So
the service level of highway will be degraded again.
