公路基层材料水泥稳定粒料施工检测及质量控制

Construction Inspection and Quality Control of Cement Stabilized Aggregate for Highway Base Material

本文以水泥稳定粒料的收缩性能为研究对象,为了更准确地验证水泥稳定粒料的收缩性能,首先阐述了水泥稳定粒料的特点,并结合温缩机理,通过收缩试验得出养生和使用龄期不同对温缩和干缩应变的主、次地位的影响规律。一般情况下水泥稳定粒料混合料的干缩应变更大,因此在冻土地区基层施工中,应注重加强质量控制,提高其路用性能。

This article takes the shrinkage performance of cement stabilized pellets as the research object.In order to verify the shrinkage performance of cement stabilized pellets more accurately,the characteristics of cement stabilized pellets are first explained,and combined with the temperature shrinkage mechanism,the curing and use Different ages affect the primary and secondary status of temperature shrinkage and dry shrinkage strain.Under normal circumstances,the shrinkage strain of cement stabilized aggregate mixture is greater.Therefore,in the construction of the base layer in the frozen soil area,attention should be paid to strengthening quality control and improving its road performance.
