| 摘 要： | 本文对道路养护中的结构性加铺层进行了分析。提出以路表回弹弯沉值、弯拉应力分别作为整体刚度、疲劳开裂的设计指标，以面层内的剪应力作为验算指标。针对重载道路特点，提出了加铺层典型结构组合及其适用性，以供道路养护时作为参考。

| Abstract: | This paper analyzes structural overlay in road mai-ntenance. The road surface rebound deflection and flexural te-nsile stress is taken as design index of overal stiffness, fatigue cracking, in the surface layer the shearing stress is as the che-cking index. According to the characteristics of the heavy road, puts forward the overlay structure combination and its appli-cability, as reference for road maintenance. |
