Anti-crack and anti-seepage steel slag pavement base mixture and preparation method thereof
The invention relates to the technical field of roadbed materials and preparation thereof, in particular to an anti-crack and anti-seepage steel slag pavement base mixture and a preparation method thereof. The anti-crack and anti-seepage steel slag pavement base mixture is prepared from steel slag, common sand, bentonite, fly ash, fibers, cement and water according to the following steps of: fullystirring the steel slag, the common sand, the bentonite and the fibers to obtain a mixture; adding water into the mixture, fully mixing, sealing and standing to obtain a mixture; and adding cement, fly ash and the remaining water into the mixture to obtain the anti-crack and anti-seepage steel slag pavement base mixture. The raw materials are easy to obtain, the preparation method is simple and convenient, the obtained anti-crack and anti-seepage steel slag pavement base mixture meets the strength, rigidity and water stability of a pavement base structure, the crack resistance and seepage resistance can be improved, cracks caused by temperature stress and shrinkage can be reduced, and meanwhile, the erosion resistance, wear resistance and durability can be improved.
本发明涉及路基材料及其制备技术领域，是一种抗裂防渗钢渣路面基层混合料及其制备方法，前者原料包括钢渣、普通砂、膨润土、粉煤灰、纤维、水泥、水，按照下述步骤制备得到：将钢渣、普通砂、膨润土和纤维充分搅拌得到拌合物，向拌合物中加入水后，充分拌和，并密闭静置得到混合物；将水泥、粉煤灰和剩余的水加入混合物，得到抗裂防渗钢渣路面基层混合料。本发明的原料易得，制备方法简便，得到的抗裂防渗钢渣路面基层混合料既满足路面基层结构的强度、刚度、水稳定性，能改善抗裂性和防渗性，又能降低温度应力和收缩而产生的裂缝，同时能提高抗侵蚀、耐磨、耐久性能。
