近年来超载现象越来越严重,国内许多省份调查,超载车占货车总数的70%～80%,超载会加速路面结构的破坏,因此研究超载对路面的影响具有重要的意义。本文通过计算水泥和沥青两种路面在不同超载作用下的弯沉值,分析了轴载与弯沉值之间的关系,量化了超载对路面的不利影响,对设计和验收等具有一定的参考价值。
Overloaded in recent years, the phenomenon of more and more serious, many domestic provinces surveyed, overloaded trucks account for 70% of the total number of trucks 80%, overload will accelerate the destruction of pavement structure, so study the impact of overload on the road is of great significance. In this paper, by calculating the deflection values of cement and asphalt under different overloading, the relationship between axle load and deflection is analyzed, and the adverse effects of overloading on the road surface are quantified, which has certain reference to design and acceptance value.
