广西大厚度水稳基层施工技术前景探讨

Discussion on the Construction Technology Prospect of Large-thickness Water Stable Base Layer in Guangxi

文章针对广西高等级沥青路面基层施工技术进行探讨,分析了水泥稳定碎石基层施工工艺存在的问题,结合国内外研究及实体工程应用现状,总结阐述了大厚度水稳基层施工技术的工程应用历程及技术的可行性;将《公路路面基层施工技术细则》(2015版)与大厚度水稳基层施工进行对比解读,发现现行规范部分条例不能满足大厚度水稳基层施工要求,因此,区域性地推广大厚度水稳基层技术需要相应的标准或指南配套实施。

This article discusses the construction technology of high-grade asphalt pavement base layer in Guangxi,analyzes the problems existing in the construction technology of cement stabilized macadam base layer,and summarizes the engineering application process and the feasibility of large-thickness water-stable base layer construction technology in combination with the domestic and foreign research and physical engineering status;after comparing the“Technical Rules for Highway Pavement Base Layer Construction Technology”(2015 Edition) with the construction of large-thickness water-stable base layer,it finds out that some regulations in current specifications cannot meet the construction requirements of large-thickness water-stable base layer,therefore,the regional promotion of large-thickness water-stable base layer technology requires the implementation of corresponding standards or guidelines.
