Asphalt concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to asphalt concrete and a preparation method thereof. The modified asphalt is prepared from the following components in parts by weight: 15 to 25 parts of asphalt; 10 to 20 parts of basalt fiber; 4-8 parts of hollow alumina-zirconia fiber; 20 to 30 parts of fly ash; 30-40 parts of iron tailing powder; 25 to 29 parts of water; and 6-10 parts of a silane coupling agent. By adding the silane coupling agent, the dispersity of the fiber in the asphalt can be improved, the bonding strength of the fiber and the asphalt is improved, and the improvement of the mechanical property of the asphalt concrete is further influenced; by adding the fiber material, the fiber material has the effects of bridging, reinforcement, grid constraint and section enhancement, so that various properties of the asphalt concrete are improved. The concrete prepared by the invention has an excellent application prospect.
本发明属于混凝土技术领域，具体涉及一种沥青混凝土及其制备方法。按重量份计，包括以下组分：沥青15‑25份；玄武岩纤维10‑20份；中空氧化铝‑氧化锆纤维4～8份；粉煤灰20‑30份；铁尾矿粉30‑40份；水25‑29份；硅烷偶联剂6‑10份。通过添加硅烷偶联剂可以改善纤维在沥青中的分散性的通式改善纤维与沥青的结合强度，进而影响沥青混凝土的力学性能的改善；通过添加纤维材料，其具有桥接与加筋、网格约束和截面增强作用，使得沥青混凝土的各项性能均得到了提升。即本发明的制备的混凝土具有优异的应用前景。
