摘 要: 二灰碎石基层路面在使用过程中会出现膨胀起拱损坏。该文在分析二灰碎石膨胀原因的基础上,采用针对性研制的地聚合物掺料对原来损坏的基层路面进行了现场修复试验,试验结果表明,采用这种技术能够充分利用原有基层材料,修复后的基层强度满足设计要求;但是在施工过程中要严格控制含水率的影响,这对施工技术提出了更高的要求。 Lime-fly ash concrete foundation pavement would expanded and hunched up to damage during use.Based on analysis of reasons for expansion of Lime-fly ash concrete,with the specially developed polymer admixture,the on-site repair test on damaged pavement was execute.Test results show that:this technology can make full use of the existing base material;strength of the base after the restoration meets the design requirements;but in the construction process the influence of moisture content should by strictly controlled,it puts forward higher requirements for construction technology.
