Multifunctional iron tailing asphalt pavement material and preparation method thereof
The invention provides a multifunctional iron tailing asphalt pavement material and a preparation method thereof. The multifunctional iron tailing asphalt pavement material is prepared from the following raw materials: aggregate and composite modified asphalt. The composite modified asphalt is prepared from the following raw materials: asphalt and an additive. The additive is prepared from the following raw materials: tetrahydropyrane ether, N-(beta-aminoethyl)-gamma aminopropyl-methyl-trimethoxy silane and potassium hypobutoxy. The aggregate is prepared from the following raw materials: iron tailings, iron tailing sand, iron tailing powder, oil-rich regenerated aggregate, waste rubber particles and aromatic polyamide fibers. Independent addition of N-(beta-aminoethyl)-gamma aminopropyl-methyl-trimethoxysilane and potassium hypobutoxide does not improve the ice inhibition capability of the asphalt pavement material, and under the condition of simultaneous addition of N-(beta-aminoethyl)-gamma aminopropyl-methyl-trimethoxysilane and potassium hypobutoxide, the ice inhibition effect of the asphalt pavement material is significantly enhanced.
本发明提供了一种多功能铁尾矿沥青路面材料及其制备方法，由以下原料制成：集料和复合改性沥青。复合改性沥青由以下原料制成：沥青和外加剂。外加剂由以下原料制成：四氢吡喃醚、N‑(β‑氨乙基)‑γ氨丙基‑甲基‑三甲氧基硅烷和次丁氧基钾。集料由以下原料制成：铁尾矿石、铁尾矿砂、铁尾矿粉、富油再生集料、废旧橡胶颗粒和聚芳酰胺纤维。N‑(β‑氨乙基)‑γ氨丙基‑甲基‑三甲氧基硅烷和次丁氧基钾单独添加均不会提高沥青路面材料的抑冰能力，二者同时添加的情况下沥青路面材料的抑冰效果显著增强。
