用传统的水泥稳定土路面基层，未能获得技术经济上的满意效果。作者研制了一种以矿渣、石灰为主剂，复合几种固化素而成的新型土壤固化剂——ＨＳ干硬性土壤固化剂。研究表明：该固化剂自身凝结硬化慢，用于固化土时，除延迟碾压时间长外，还具有强度高、微膨胀等特点 The use of traditional cement to stabilize the soil pavement basement has failed to achieve satisfactory technical and economic results. The authors developed a new type of soil solidifying agent, HS dry-hardening soil solidifying agent made of slag and lime as the main agent and compounding several solidifying agents. Studies have shown that the curing agent itself is slow to set and harden, and when it is used to solidify soil, it has high strength and micro-expansion, in addition to a long delay in rolling time.
