公路改建基层冷再生施工工艺及注意事项

Cold Regeneration Construction Technology and Cautions of Rebuilding Highway Base

该文通过分析公路改建工程就地冷再生基层的手段,确定了科学全面的配合比设计施工方法、检测手段,从而形成了一系列的监理经验和成果,为推进公路材料的循环利用提供了指导和范例。同时,通过试验段取得的数据对水泥稳定碎石所用的材料、配合比、松铺系数、施工工艺及碾压次数进行了归纳总结,形成了标准的施工方法进而指导工程的大面积施工。

Through analyzing the measures of highway rebuilding engineering＇s cold in-place regeneration base, the paper confirms the scientific and comprehensive mix proportion design ~ construction method and testing means, thereby gains a series of supervision experience and achievements, and provides guidance and example for promoting highway material recycling. In the mean time, it also summarizes the materials, mix proportion, coefficient of loose laying, the construction technology and the rolling frequency of cement stabilized macadam from test section data, and forms a standardized construction method to guide the large-area engineering construction.
