土凝岩固化黏性土路用性能试验研究

采用无侧限抗压强度试验、击实试验、抗疲劳性能试验和水稳定性试验，对土凝岩固化黏性土与水泥固化黏性土的力学及耐久性能进行对比，探究其性能变化规律。结果表明:随土体固化剂掺量增加，固化稳定黏性土7 天无侧限抗压强度增大，其最佳含水率也随之增大；水泥固化稳定黏性土的早期水稳定性系数低于土凝岩固化黏性土，后期水稳定性系数较为接近。

Experimental Study on Road Performance of Soil Condensate Solidified Clay Soil

The unconfined compressive strength test, compaction test, fatigue resistance test and water stability test are used to compare the mechanical and durability properties of soil condensate solidified clay soil and cement solidified clay soil in order to explore its performance changes. The results show that with the increase of the soil curing agent content, the 7d unconfined compressive strength of the solidified stabilized clay soil will increase, and the optimal moisture content will increase accordingly; the early water stability coefficient of the cement solidified stabilized clay soil is lower than that of the soil condensate solidified clay soil and their later water stability coefficient are close to each other.
