Asphalt waste powder roadbed material and preparation method thereof
The invention belongs to the field of solid waste recycling, particularly relates to resource utilization of waste asphalt powder, and particularly relates to a waste asphalt powder roadbed material and a preparation method thereof. The waste asphalt powder roadbed material is prepared from the following raw materials in percentage by weight: 60 to 90 weight percent of waste asphalt powder, 3 to 40 weight percent of Portland cement, 1 to 10 weight percent of sodium silicate and 4 to 8 weight percent of quick lime, the concrete also comprises a water reducing agent and a defoaming agent; the water reducing agent accounts for 0.1-2wt% of the total weight of the raw materials; the defoaming agent accounts for 0.01-1wt% of the total weight of the raw materials. The problems that the mixing amount of asphalt waste powder is too small, the recycling rate of asphalt waste is low, and cost reduction is not obvious are solved. The problems that the asphalt waste powder depends on an organic curing agent, environmental pollution is easily caused, and environmental unfriendliness is caused are solved. The problem that most heavy metal ions such as iron, aluminum and manganese in soil except mercury ions pollute the environment is solved.
本申请属于固体废弃物回收利用领域，尤其是指沥青废粉的资源化利用，具体涉及一种沥青废粉路基材料及其制备方法。沥青废粉路基材料，包括以下重量百分比的原料：沥青废粉60‑90wt％，再加入硅酸盐水泥3‑40wt％、硅酸钠1‑10wt％、生石灰4‑8wt％；还包括减水剂、消泡剂；所述的减水剂占原料总重量的0.1‑2wt％；所述消泡剂占原料总重量的0.01‑1wt％。解决沥青废粉掺入量过少、沥青废料回收再利用率低，成本缩减不明显的问题。解决沥青废粉依赖有机固化剂易造成环境污染，对环境不友好的问题。解决消除或降低土壤中除汞离子以外的铁、铝、锰等大部分重金属离子污染环境的问题。
