旧沥青混凝土路面冷再生是利用旧路沥青混凝土及上基层经破碎加入水泥均匀拌和,在最佳含水量条件下碾压获得的半刚性结构。因此在工程开工前应认真对旧路沥青混凝土及上基层材料的种类、厚度等进行调查,以确定铣刨机作业速度,并实现混合料破碎后配比合理。本文对沥青混凝土旧路路面冷再生的施工工艺进行了总结。
The cold regeneration of the old asphalt concrete pavement is the semi-rigid structure obtained by crushing the asphalt concrete of the old road and the upper base by crushing and adding the cement uniformly and rolling under the optimum moisture content. Therefore, before the commencement of the project, the types and thicknesses of asphalt concrete in the old road and the material of the upper grass-roots should be carefully investigated to determine the operating speed of the milling machine and to achieve a rational ratio after the mixture is crushed. This article summarizes the construction technology of cold regeneration of asphalt pavement old road.
