超载对道路使用性能的影响及超载系数的合理确定

The Effect on Road Performance by Over-loading and the Choice of Over-loading

对天津市车辆超载问题进行研究 ,根据车辆超载引起路面的破坏 ,提出求取代表车型的超载系数来考虑超载对路面的影响 ,避免路面设计的不尽合理 ,所确定的超载系数为天津市道路设计及交通管制提供技术支持。

Based on progressive over-loading,this paper studies its features for asphalt concrete pavement in Tianjin,and puts forward the way that consider the over-loading of pavement and avoids reasonless pavement design by derived over-loading coefficient of representative vehicle.The assured over-loading coefficient can be put into practical uses in the road deaign and traffic manage for Tianjin.
