Soil stabilizer, layered pavement structure and construction method of layered pavement structure
The invention relates to the technical field of road construction, in particular to a soil stabilizer, a layered pavement structure and a construction method of the layered pavement structure. The soil stabilizer provided by the invention realizes reutilization of solid wastes such as waste mine soil on a construction site, and has the characteristics of low carbon and environmental protection. In the soil curing agent, the solid waste, the polyacrylamide, the beta-sodium naphthalene sulfonate-formaldehyde condensate, the diethanolisopropanolamine, the calcium chloride and the sulfamate high-efficiency water reducing agent play a synergistic role, so that the soil curing agent has good curing capacity and waterproof capacity on various soils; the soil stabilizer can polymerize and solidify loose soil particles under a dry or wet condition, and the solidified soil has higher compaction density and compressive strength (unconfined compressive strength is higher than 2MP after solidification for 7 days), so that the soil stabilizer is an ideal low-carbon environment-friendly heavy-load road building material.
本发明涉及道路施工技术领域，具体涉及一种土壤固化剂、一种层状路面结构及其修筑方法。本发明提供的土壤固化剂，实现了施工现场废弃矿土等固废物的再利用，具有低碳、环保的特点。在该土壤固化剂中，固废物与聚丙烯酰胺、β‑萘磺酸钠甲醛缩合物、二乙醇单异丙醇胺、氯化钙以及氨基磺酸盐高效减水剂协同发挥作用，对各类土壤均具有良好的固化能力和防水能力，在干燥或者湿润的条件下均能够使松散的土壤颗粒聚合并固化，并且固化后的土壤具有较高的压实密度和抗压强度(固化后7天无侧限抗压强度高于2MP)，因此该土壤固化剂是理想的低碳环保重载筑路材料。
