High-performance steel slag cold-mixed and cold-laid wearing layer material and preparation method thereof
The invention discloses a high-performance steel slag cold-mixed and cold-laid wearing layer material and a preparation method thereof. The wearing layer material comprises mineral aggregate, waterborne epoxy modified emulsified asphalt, cement, sodium tripolyphosphate and water in a weight ratio of 100: (8-14): (2-4): (3-5): (5-12). The mineral aggregate comprises steel slag aggregate, diabase aggregate and limestone mineral powder, and the waterborne epoxy modified emulsified asphalt comprises cationic emulsified asphalt, methyl cellulose, SBR styrene-butadiene latex, waterborne epoxy resin emulsion and a curing agent; the preparation method comprises the following steps: sequentially adding the steel slag aggregate, the diabase aggregate, the limestone mineral powder, the sodium tripolyphosphate, the cement and the water into a mixing basin at normal temperature, and uniformly stirring; compared with a conventional cold-mixing preventive maintenance technology, the high-performance steel slag cold-mixing and cold-paving wearing layer material has the advantages of being high in binding power and good in skid resistance and durability, meanwhile, high-valued and large-scale utilization of the steel slag solid waste can be achieved, and the high-performance steel slag cold-mixing and cold-paving wearing layer material is obtained. The method has remarkable economic benefits and ecological benefits.
本发明公开了一种高性能钢渣冷拌冷铺磨耗层材料及制备方法，磨耗层材料包括矿料、水性环氧改性乳化沥青、水泥、三聚磷酸钠和水的重量比为100:8～14:2～4:3～5:5～12；矿料包括钢渣集料、辉绿岩集料和石灰岩矿粉，水性环氧改性乳化沥青包括阳离子乳化沥青、甲基纤维素、SBR丁苯胶乳、水性环氧树脂乳液和固化剂；制备方法为：将钢渣集料、辉绿岩集料、石灰岩矿粉、三聚磷酸钠、水泥、水在常温下依次加入拌和盆中搅拌均匀；随后将水性环氧改性乳化沥青加入，在常温下继续拌和均匀制得高性能钢渣冷拌冷铺磨耗层材料，相较于常规冷拌型预防性养护技术，具有粘结力强、抗滑耐久性好的优点，同时可实现钢渣固废的高值化、规模化利用，具有显著的经济效益和生态效益。
