Research on Material Composition Design and Durability of HighwayWater Stable and Cold Recycling Base Course

水稳冷再生材料可有效降低工程造价,因其良好的路用性能在大中修项目中得到了较多应用,论文在分析水稳冷再生材料强度形成机理基础上,通过室内试验对水稳冷再生基层材料组成设计进行了设计配比以及力学性能的研究,提出了建议水泥剂量与旧料掺配比例的关系,利用疲劳研究方法对再生基层结构的耐久性进行了分析,期望为相关工程技术人员提供借鉴。

Water-stable cold-recycled materials can effectively reduce engineering costs. Because of their good road performance, they have been widely used in large and medium repair projects. Based on the analysis of the strength formation mechanism of water-stable cold-recycled materials, this paper analyzes the water-stable stability through laboratory tests. The composition design of cold-recycled base materials was studied for design proportion and mechanical properties, and the relationship between the recommended cement dosage and the proportion of old materials was put forward. The durability of the recycled base structure was analyzed using fatigue research methods.It is expected to be related engineering. Technical personnel provide reference.
