不同崩解条件下泥质红砂岩路用性能试验研究

工程实践表明红砂岩在遇水情况下易崩解，且崩解后红砂岩的物理性质变化较大。以湖南长沙某环保科技园工地现场泥质红砂岩为研究对象，通过崩解试验和击实试验对不同条件下红砂岩的崩解情况和红砂岩崩解后的最佳含水量、最大干密度等物理性质进行试验研究，表明不同崩解条件下红砂岩崩解后的差异性，为红砂岩在路基工程中的应用提供参考。

Experimental Study on Road Performance of Muddy Red Sandstone under Different Disintegration Conditions

The practical ＇work shows that red sandstone is easily disintegrated in water and its physical properties will change a lot after the disintegration. Taking the muddy red sandstone in the field of certain environment-protected industrial park in Changsha, Hunan as the object of study, the disintegration under different conditions is studied through disintegration and compaction tests with its physical properties such as optimum water content, maximum dry density tested after disintegration. Thus the difference of red sandstone after disintegration under different conditions is indicated offering reference to application of red sandstone in subgrade engineering.
