水泥乳化沥青砂浆充填层是无砟轨道施工质量控制的关键和难点,材料配方复杂,环境敏感性高,施工工艺要求严格,目前在国内的应用尚不成熟,施工过程中存在着离缝、灌注不饱满以及侧边不平整等病害。本文结合石武客专河南段的施工经验,针对水泥乳化沥青砂浆充填层存在的质量缺陷,从修补材料、施工过程和工艺、施工控制要点等方面介绍了整治方法和要求。
The filling layer of cement emulsion asphalt mortar is the key and difficult point in the construction quality control of ballastless track. The material formulation is complex, the environmental sensitivity is high and the construction technology is strict. At present, the application in China is not yet mature. Not full and uneven side and other diseases. Based on the construction experience of Shek Wuke Henan section, this paper introduces the remediation methods and requirements from the aspects of repairing materials, construction process and process, construction control points and so on, according to the quality defects of cement emulsified asphalt mortar filling layer.
