Abstract: At present the important reasons of pavement early damage is the overload of Trucks. People's nar- row sense of overload is concerned by the vehicle ｌｏａｄ. This paper analyzes the mechanical response of as- phalt pavement in the tire model, wheel, Tire pressure ｌｏａｄ. The results show that not only did the overweight cause the response of pavement stress significantly but also the mechanical impact on the road is also very un- favorable when the tire pressure is high.
