目前常温条件下碾压沥青混凝土心墙的施工技术已趋于成熟,但在严寒地区,碾压沥青混凝土防渗心墙的冬季施工技术仍处于探索阶段。针对新疆地区-碾压沥青混凝土心墙施工,通过采取优选配合比、对施工机械进行加热、保温改造、控制碾压遍数等一系列施工工艺的改进与优化,实现了碾压沥青混凝土冬季低温施工,且施工质量能得到可靠保证。
At present, the construction technology of crushed asphalt concrete core wall has matured at normal temperature. However, in winter, the winter construction technology of crushed asphalt concrete impervious core wall is still under exploration. Aimed at the Xinjiang region - rolling asphalt concrete core wall construction, through the adoption of the preferred mix, the construction machinery heating, thermal insulation transformation, control rolling over a series of construction process improvements and optimization, achieved rolling asphalt concrete winter low temperature Construction, and construction quality can be reliably guaranteed.
