The invention relates to the field of concrete pavements, and particularly discloses steel slag asphalt concrete and a preparation method thereof as well as a pavement and a construction method thereof. The steel slag asphalt concrete is characterized in that the steel slag asphalt concrete is prepared from a mineral aggregate, asphalt, a viscosity additive and a reinforcing filler, the weight ratio of the mineral aggregate to the asphalt is 4-4.5%, the mixing amount of the viscosity additive is 0.3-0.4% of the total weight of the mineral aggregate and the asphalt, and the mixing amount of the reinforcing filler is 0-0.6% of the total weight of the mineral aggregate and the asphalt; and the mineral aggregate is formed by mixing the following raw materials in percentage by weight: 33-36% of coarse steel slag, 47-52% of fine steel slag, 10-13% of limestone and 4-6% of mineral powder. The steel slag asphalt concrete disclosed by the invention has relatively good stability and water erosion resistance.
本申请涉及混凝土路面领域，具体公开了一种钢渣沥青混凝土及其制备方法及其路面及施工方法。钢渣沥青混凝土，其特征在于，由矿料、沥青、粘度添加剂和增强填料制备而成，其中，矿料与沥青的重量比为4‑4.5%，粘度添加剂的掺量为矿料和沥青总重量的0.3‑0.4%，增强填料的掺量为矿料和沥青总重量的0‑0.6%；矿料由以下重量百分比的原料混合而成：33‑36%的粗钢渣，47‑52%的细钢渣，10‑13%的石灰岩和4‑6%的矿粉。本申请的钢渣沥青混凝土具有较好的稳定性和抗水侵蚀的性能。
