摘要
为解决红黏土路基胀缩率较大等性能缺陷,通过加入ISS土壤固化剂对其进行改性,并通过室内试验对ISS固化红黏土的性能进行了研究。室内试验表明:ISS固化剂的掺入有效降低了红黏土的塑性指数,但红黏土的塑性指数并不是随ISS固化剂掺入浓度增大而减少,浓度增大时,塑性指数反而增加;ISS固化剂的最佳掺入比为ISS∶水=1∶200(体积);ISS固化剂的掺入有效地降低了红黏土的膨胀性能,增强了其抗剪切性能与无侧限抗压强度。
In order to solve the problem of red clay subgrade expansion shrinkage properties of the defects,by adding ISS soil solidifying agent which was modified,and carried out the research on the properties of ISS curing red clay by indoor test. The experimental results show that the addition of ISS curing agent can effectively reduce the plastic index of red clay,but the plastic index of red clay is not decreased with the increase of the concentration of ISS curing agent. When the concentration increases,the plasticity index increases; The optimum mixing ratio of ISS curing agent is ISS ∶ water = 1 ∶ 200（ volume）; the incorporation of ISS curing agent can effectively reduce the swelling property of red clay,and enhance the shear strength and unconfined compressive strength.
