摘要
在广西G324线岑溪至容县一级公路路面大修工程(梧州段)中,对其水泥稳定碎石基层采用的是就地冷再生的施工技术和方法。结合该工程,对掺水泥的水泥稳定碎石冷再生基层进行综合研究,分析其配合比设计方法,并铺筑试验段,验证其使用效果,分析其经济效益,可为今后的沥青路面大修应用该技术提供借鉴。
The cold in-place recycling construction technology of cement stabilized macadam base is applied in a pavement overhaul engineering of Cenxi-Rongxian arterial road Wuzhou section of G324 in Guangxi.Combining with the practice,the cold recycling cement stabilized macadam base with cement addition is studied synthetically.The design method of its mix proportion is analyzed.By spreading test section,its service effect is validated,and its economic benefit is analyzed,which can provide reference for overhaul of asphalt pavement in future.
