    Generally, the process of pavement deterioration occurs before the macrocrack appearing in asphalt pavement structure. It is always useful to understand the causes of pavement cracking and present preventive measures. In this paper, damage regularity of asphalt pavement under the condition of repeated loading is studied in terms of dynamic damage finite element method. The software ABAQUS was used for calculation and subroutine of damage was obtained by using the interface of the vectorized user material routine. The relationships between the times of loading and the damage degree, maximum tension stress of element and maximum tension strain of element are analyzed and discussed.
