Solid waste asphalt mixture for concrete pavement and preparation method thereof
The invention relates to a solid waste asphalt mixture for a concrete pavement and a preparation method of the solid waste asphalt mixture. The solid waste asphalt mixture comprises the following rawmaterials in parts by weight: 4-9 parts of natural sand, 4-9 parts of machine-made sand, 12-27 parts of iron tailings, 38.5-52.5 parts of asbestos tailings, 16.5-22.5 parts of basalt aggregate, 4-6 parts of asphalt, 0.2-0.4 part of asphalt modifier, 3-5 parts of modified desulfurized ash and 2-3 parts of iron tailing sand. According to the invention, the industrial solid waste iron tailings, asbestos tailings and steel slag are used as raw materials, the prepared asphalt mixture has good rut deformation resistance and good temperature stability, and the addition of the modified desulfurized fly ash can improve the adhesion between the asphalt and the aggregate, so the asphalt mixture has good enterprise benefits. Not only is the pavement performance of the asphalt mixture ensured to meet various index requirements, but also the solid waste is fully utilized, and the influence of tailing stacking on the environment is reduced.
本发明一种混凝土路面用固废沥青混合料及其制备方法，包括以下重量份的原料：天然砂4‑9份、机制砂4‑9份、铁尾矿12‑27份，石棉尾矿38.5‑52.5份、玄武岩集料16.5‑22.5份、沥青4‑6份、沥青改性剂0.2‑0.4份、改性脱硫灰3‑5份、铁尾矿砂2‑3份。本发明以工业固废铁尾矿、石棉尾矿和钢渣为原料，制得的沥青混合料具有良好的抵抗车辙变形能力和良好的温度稳定性，同时改性脱硫灰的掺入，可以提高沥青与集料之间的黏附性，具有良好的企业效益。既保证了沥青混合料的路用性能满足各项指标要求，又充分利用了固废，减少了尾矿堆放对环境的影响。
