一、超限运输严重破坏公路及其设施,增加公路维护费用,缩短公路使用寿命。在公路上行驶的汽车,其轴载质量对路面是一种重复性的疲劳作用,当轴载质量增大后,公路路面在有效使用期内能够承受弹性变形的次数(即汽车行驶次数)大为减少。车辆行驶造成的公路路面破坏,与车辆的轴载质量呈指数关系,超限(载)运输因轴载质量提高,
First, overloaded transportation seriously damaged the highway and its facilities, increased road maintenance costs and shorten the service life of the highway. When driving on a highway, the axle load quality is a repetitive fatigue effect on the road surface. When the mass of the axle load increases, the number of times the highway pavement can withstand the elastic deformation (that is, the number of vehicle trips) during the effective use period is large To reduce. The road pavement damage caused by the vehicle driving is exponential with the axle load quality of the vehicle. The overrun (load) transportation is deteriorated due to the increase of the axle load quality,
