摘要
沥青路面在超载交通作用下出现早期疲劳开裂,主要是由于路面面层的剪应力过大所造成,所以路面设计应该考虑超载因素,以保证路面设计的可靠性。
The showed early crack on asphalt pavement under the action of traffic overload are caused chiefly owing to excessive shear stress of surface. Therefore, the overload factors should be taken into account as designing the pavement to ensure reliability of the design.
