Steel slag asphalt concrete with good anti-rutting performance and preparation method thereof
The invention provides steel slag asphalt concrete with good anti-rutting performance and a preparation method thereof. The steel slag asphalt concrete with good anti-rutting performance comprises thefollowing raw materials: cement, coarse aggregate, fine aggregate, asphalt, filler, a fiber stabilizer and a phase change material. The steel slag asphalt concrete is mainly composed of cement, coarse aggregate, fine aggregate, asphalt, filler, a fiber stabilizer and a phase change material; by means of the fiber stabilizer, mutual combination of the raw materials can be promoted, and the viscosity of the asphalt mixture is further improved, so that good low-temperature anti-cracking performance is achieved; by means of the phase change material, the cement and the fine aggregate, the steel slag is added into the concrete, so that a certain neutralization effect on chemical components in the steel slag is achieved, great reaction with the chemical components in the steel slag is avoided,the original physical properties of the raw materials are maintained, the stability of the concrete is further improved, the anti-rutting performance of the concrete is further improved, and the service life of the concrete is prolonged.
本发明提供一种抗车辙性能好的钢渣沥青混凝土及其制备方法。所述抗车辙性能好的钢渣沥青混凝土，包括如下原料：水泥、粗集料、细集料、沥青、填料、纤维稳定剂和相变材料。该钢渣沥青混凝土，主要由水泥、粗集料、细集料、沥青、填料、纤维稳定剂和相变材料组成，其中通过添加纤维稳定剂，能够促进各原料之间相互结合，进而提高沥青混合料的粘黏性，使得其具有良好的低温抗裂性能，再配合相变材料、水泥和细集料，对钢渣内部的化学成分起到一定的中和作用，避免与钢渣内部化学成分发生较大程度的反应，保持各原料原有的物理性质，使得混凝土的稳定性得到进一步提升，进而提升了混凝土的抗车辙性能，并延长了使得混凝土的使用寿命。
