Abstract

With the help of ABAQUS and its subroutine DLOAD calculated the asphalt pavement response of different pothole area and combination of pavement structural from moving load.So as to arrive the law of development to pothole and the best combination of pavement structure to resist the pothole .Results show that the inflection point in the development of pothole is 53.25cm×53.25cm of pothole area; The best combination of pavement structure to resist the pothole is 4.5cm+6cm+9.5cm.The results could use to define the best time to repair pothole, and provide the best combination of pavement structural to resist pothole.
