复合式基层沥青路面结构动力响应分析

Some deficiencies exist in current asphalt pavement design methods without taking the effects of dynamic load into account. In this paper the three – dimensional (3D) finite element dynamic method was adopted and a three - dimensional (3D) finite element model for asphalt pavement with composite base under the moving load was established. Some mechanical response of pavement induced by moving load was analyzed. Finally, the mechanical regularity impacted by vehicle speed was compared. The results show that, with the increasing of the vehicle speed, the maximum value of dynamic response became smaller.
