High-stability steel slag asphalt mixture and preparation method thereof
The invention belongs to the technical field of pavement materials, and particularly relates to a high-stability steel slag asphalt mixture and a preparation method thereof. The high-stability steel slag asphalt mixture is prepared from the following raw materials in parts by weight: 60 to 80 parts of coarse aggregate steel slag with the particle size of greater than 2.36 mm, 40 to 60 parts of fine aggregate stone with the particle size of less than 2.36 mm, 10 to 15 parts of modified mineral powder, 20 to 25 parts of 90 # matrix asphalt, 15 to 30 parts of steel slag stabilizer and 0.4 to 0.5 part of asphalt modifier. The stability of the steel slag asphalt mixture is greatly improved, and the durability of a pavement can be enhanced by adopting the mixture.
本发明属于路面材料的技术领域，具体的涉及一种高安定性钢渣沥青混合料及其制备方法。该种高安定性钢渣沥青混合料，包含以下重量份的原料：粒径大于2.36mm的粗骨料钢渣60‑80份，粒径小于2.36mm的细骨料石料40‑60份，改性矿粉10‑15份，90号基质沥青20‑25份，钢渣稳定剂15‑30份，沥青改性剂0.4‑0.5份。该钢渣沥青混合料的安定性得到大幅度提高，采用该混合料能够使得路面的耐久性得到增强。
