Abstract: This paper presents the methods to evaluate calculating-resilient modulus of the bases for different types of concrete pavement overlays and the effect of crack of existing CCP on base capacity based on the testing-analysis results of in-service test section built in Jinhua, and then it shows how to determine base calculating-resitjent modulus.

Key words: existing cement concrete pavement(CCP), structural capacity, overlay, resilient modulus

摘要： 本文以金华330国道中的试验路段为依据,通过测试和计算分析,提出了不同加铺结构类型设计时,基础顶面计算回弹模量的取值方法,以及按照旧路面板破损状况,对基础强度进行修正的方法。本文研究结果,可供修订砼路面结构设计规范参考。
