Preparation method and application of road base composite soil stabilizer
The invention discloses a preparation method and application of a road base composite soil stabilizer, during mix proportion design, a compaction test is carried out according to the mix proportion designed by test groups, the optimal moisture content and the maximum dry density of each test group are determined, an unconfined compressive strength test piece is prepared for maintenance, and based on the unconfined compressive strength test result, the road base composite soil stabilizer is obtained. And determining the optimal dosage of the plastic limit water-resistant agent and the mixing ratio of cement to lime soil. The soil stabilizer is suitable for soil types such as soft soil with high water content and expansive soil with poor water stability, and is wide in application range. The road base soil curing agent is simple in preparation process and mild in preparation condition, the curing agent added into soil can react with the soil and enhance the compressive strength of the soil, and the curing agent is simple in preparation method, low in cost, capable of meeting the requirements for repairing soft soil, improving the strength of a base and the like and good in application and popularization effect.
本发明公开了一种道路基层复合土壤固化剂的制备方法及其应用，在配合比设计时，按照试验组设计配合比进行击实试验，确定各试验组的最佳含水率与最大干密度，制备无侧限抗压强度试件进行养护，并基于无测限抗压强度测试结果，确定塑限抗水剂最佳剂量和水泥石灰土配合比。所述土壤固化剂适用于含水量大的软土、水稳定性差的膨胀土等土体类型，应用范围广。本发明道路基层土壤固化剂制备工艺简单，制备条件温和，土壤中加入该固化剂，能够与土壤发生反应，增强土壤抗压强度，且固化剂的制备方法简单，成本低廉，能满足软土修复、提高基层强度等要求，具有良好推广使用效果。
