摘要
以广贺高速为依托,从分析裂缝成因入手,经过室内配料制件实验以及实验段的施工验证,在广东省首次提出用振动成型法进行密实骨架结构半刚性基层配合比设计。由试验段的后期跟踪结果来看,骨架密实型结构水泥稳定碎石基层的裂缝明显减少,效果显著。
As the basis on GUANGHE highway,from the analysis of cracks,indoor experiments and verification from experimental construction n of workpiece is started.It＇s the first time to use the Vibration molding method design semi-rigid dense skeleton in Guangdong Province.From the results of the t experimental construction,the cracks of skeleton dense structure of cement stabilized gravel,are decreased obviously.
