通过对公路运输车辆普遍存在超载问题的研究， 从标准轴载的当量作用次数和超轴载作用入手， 得出超载是路面结构早期破坏的重要原因之一。提出路面结构设计应充分考虑超载运输影响。
Based on the research on the common overload problem of road transport vehicles, starting from the equivalent number of axle loads and the effect of over-axle load, it is concluded that overloading is one of the important reasons for the early damage of pavement structure. It is suggested that pavement structure design should fully consider the influence of overloading.
