摘要
分析了公路水泥混凝土路面发生损坏的主要原因,探讨了如何评定旧混凝土的路面路况,重点介绍了旧混凝土路面加铺厚度的计算,指出混凝土路面结构厚度设计应考虑车辆超载带来的潜在不利因素,从而使路面加铺结构和厚度满足承载荷载应力和温度应力的综合疲劳作用。
It analyses the main reasons of the damage of road cement concrete pavement, discusses how to appraisal the old concrete pavement settlement, mainly introduces the calculation of old concrete pavement adding spread thickness, and points out that the design of concrete pavement adding spread structure thickness should consider the potential factors of over loading, this makes the pavement adding spread structure and thickness meet the need of the combined fatigue action of bearing stress and temperature stress.
