High-toughness and high-modulus asphalt mixture and preparation method thereof
The invention belongs to the technical field of road traffic transportation engineering, and relates to a high-toughness and high-modulus asphalt mixture and a preparation method thereof. The raw materials comprise, by mass, aggregate, modified asphalt, a high-toughness modifier, a high-modulus modifier and a fiber stabilizer, and the aggregate comprises at least one of steel slag, basalt and diabase; the high-toughness modifier comprises at least one of a polyethylene octylene copolymer elastomer, a methyl acrylate-butadiene-styrene copolymer and ethylene propylene diene monomer; the high-modulus modifier is formed by mixing steel slag micropowder, a coupling agent, extract oil, epoxy resin and an ethylene-vinyl acetate copolymer. The high-toughness and high-modulus asphalt mixture prepared by the invention has excellent rutting resistance and flying resistance, the characteristics of high strength of the steel slag coarse aggregate and good filling property of the steel slag micro powder are fully played, and the cohesive force and strength of the asphalt mixture are jointly improved by the steel slag coarse aggregate and the styrene-butadiene-styrene block copolymer serving as an organic modifier.
本发明属于道路交通运输工程技术领域，涉及一种高韧高模量沥青混合料及其制备方法。按质量份计，原料包括集料、改性沥青、高韧改性剂、高模量改性剂和纤维稳定剂，其中，集料包括钢渣、玄武岩和辉绿岩中的至少一种；高韧改性剂包括聚乙烯辛烯共聚弹性体、丙烯酸甲酯‑丁二烯‑苯乙烯共聚物和三元乙丙橡胶中的至少一种；高模量改性剂由钢渣微粉、偶联剂、抽出油、环氧树脂和乙烯‑醋酸乙烯酯共聚物混合而成。本发明制备得到的高韧高模量沥青混合料具有优异的抗车辙和抗飞散性能，充分发挥了钢渣粗集料强度高、钢渣微粉填充性好的特点，同有机改性剂苯乙烯‑丁二烯‑苯乙烯嵌段共聚物共同提升了沥青混合料的粘聚力和强度。
