土石混合路基检测方法研究

Study on detection method of roadbed with soil-stone mixture

在分析目前各种路基压实影响因素、施工过程及检测技术特点的基础上,针对土石混合料颗粒组成和含水状态极不均匀的特点,引入最佳含水量系数对最大干容重的理论计算法进行了改进,探讨了用空隙率控制法和不同粗集料含量下改进的工地压实度控制方法作为土石混合料压实质量控制标准的可行性。

On the basis of analysing various influential factors,construction process and detection technical characters of roadbed compacting,this paper introduces optimum water content s parameter to improve theoretical computing method of maximal dry unit weight,and discusses the feasibility of taking voidage control method and improved construction site compaction degree control method under different coarse aggregate contents as soil-stone mixture compacting quality control standard.
