摘要
以营大公路路面大修工程为背景,针对路面破损严重、左右幅路面损坏程度差异明显的状况,对路面损坏原因进行分析,结果表明:重载车辆作用可造成结构损坏,使路面结构承载能力下降;路面结构强度不足是造成路面破损、使用状况不佳的主要原因;车辙主要为失稳性车辙,较重的车辆荷载、路面的二次压实是形成车辙的主要原因。
Taking the overhaul engineering of Yingkou-Dashiqiao highway pavement as the background,aiming at the situation of serious pavement damage or obvious damage difference of pavement on the left and right,the analysis on the damage reason of the pavement is made.The result shows that,the effect of overload vehicle can cause the structural damage and reduce the structural-load-carrying capacity of the pavement;insufficient structural strength of the pavement is the main reason of pavement damage or bad service condition;rutting with instability is a main form.Serious vehicle load and secondary compaction of the pavement are main reasons for rutting.
