摘要
在提出冲击压实后旧水泥混凝土路面作为加铺结构层之一的设计思路的基础上,阐述实测回弹模量的重要性;通过对大量实测承载板数据进行分析,获得了实施冲击压实处理后旧水泥混凝土板及板下基层回弹模量的量值范围和变化规律,作为加铺层设计的计算参数,并用来评价其残余承载能力。
The significance of measuring modulus of resilience based on proposed design philosophy which takes impacted and compacted existing cement concrete slab as one of structural layers for overlay design are discussed in this paper By processing lots of bearing plate testing data in situ, the magnitude and value range of modulus of resilience and its trend for existing cement concrete slabs and base course after impact and compaction are got. They can be used for evaluating remains bearing force of the pavements as useful parameters in design of overlay pavement structure
