摘要
以实际市政道路为背景,通过调查检测旧路面现状,分析道路病害成因,对路面破损程度进行分段评价.针对道路不同的破损程度,分别计算各路段的弯沉代表值和当量回弹模量,并采用弹性层状体系理论进行结构计算,拟定几种可行的结构组合及设计层,根据各方案计算结果,进行技术经济比较,确定旧路修复改造方案.
Based on municipal road of Gao Xin Xi Lu,this paper analyzes the causes of road diseases through the investigation and tests about status of old road,then segmented and evaluated road according to the extent of damagment.For different levels of road damagment,we calculated representative deflection and equivalent modulus of elasticity in various sections,then analysis the structure with elastic layer system theory,proposed several possible combinations and design layer.According to theoretical calculations,compared the various programs from the technical and economic aspects,then the repair and reconstruction program are determined.
