摘　　要：低剂量水稳底基层是路面工程的基础构造,它既起到保护路基的作用,又承担路面传导下来的荷载。因此,其施工质量决定高速公路运营期的耐久性,特别是江苏沿海城市软土地基的特点导致其施工工艺、质量控制指标要与内陆城市有些许不同。本文通过梳理当前国内低剂量水稳底基层的现状,并结合工程实例开展试验段研究工作,分析施工过程中混合料级配、最佳含水率、水泥剂量、最大干密度等质量控制指标,获得具有普适性、较完整且适用于江苏沿海城市的施工工艺。Low-dose water stabilization sub-base is the foundation structure of pavement engineering,which not only plays the role of protecting the roadbed,but also bears the load transmitted from the road surface.Therefore,the construction quality determines the durability of the expressway during the operation period,especially the characteristics of the soft land foundation in the coastal cities of Jiangsu province,and the construction technology and quality control indexes are slightly different from those in the inland cities.By combing the current situation research,analyzing the construction process of mixture gradation,optimal moisture content,cement dosage,maximum dry density quality control index,obtain the universal,complete and suitable for the construction technology of coastal cities in Jiangsu province.
