Asphalt powder-cement composite curing agent and silt curing method thereof
The invention provides an asphalt powder-cement composite curing agent and a silt curing method thereof. The asphalt powder-cement composite curing agent is prepared from the following raw materials in parts by weight: 10-60 parts of asphalt powder and 40-90 parts of cement, then uniformly mixing the asphalt powder-cement composite curing agent with silt, adding water, and jointly realizing the curing of the silt and improving the strength of the cured silt by utilizing the characteristics that gaps among silt particles are filled with the asphalt powder and a cementing substance is generated through a cement hydration reaction, so as to meet the construction requirements of roadbed filling. The raw materials of the asphalt powder-cement composite curing agent are easy to obtain, the technology for curing silt is simple, large-scale implementation is easy, the engineering problems that in natural silt roadbed filling, compaction is difficult, road durability is poor and the like are solved, and the asphalt powder-cement composite curing agent has high engineering application and popularization value.
本发明提供了一种沥青粉‑水泥复合固化剂及其固化粉土的方法，沥青粉‑水泥复合固化剂由以下重量配比的原料制备得到：沥青粉10～60份，水泥40～90份；然后将沥青粉‑水泥复合固化剂与粉土进行混匀后，加入水，并利用沥青粉填充粉土颗粒之间的孔隙、水泥水化反应生成胶凝物质的特性，共同实现对粉土的固化，提高固化后粉土的强度，以满足路基填筑的施工要求。本发明提供的沥青粉‑水泥复合固化剂的原料易得，且对粉土进行固化的工艺简单、易于规模化实施，解决天然粉土路基填筑中的压实困难、路用耐久性能差等工程问题，具有较高的工程应用及推广价值。
