Porous red mud asphalt pavement material for purifying runoff pollutants as well as preparation and application thereof
The invention relates to a porous red mud asphalt pavement material for purifying runoff pollutants as well as preparation and application thereof. The asphalt pavement material comprises asphalt, redmud and graded aggregate, the volume ratio of the asphalt to the red mud is 1: (0.3-0.4), and the mass ratio of the mass sum of the asphalt and the red mud to the graded aggregate is (0.04-0.06): 1.The preparation method comprises the following steps of heating and melting the asphalt, and respectively heating and drying the red mud and the graded aggregate, uniformly mixing the asphalt, the redmud and the graded aggregate, compacting in a mold by using a compactor, and standing to obtain an asphalt pavement material test piece, and laying an asphalt pavement material on a road, and purifying road rainwater runoff pollutants penetrating through the material. Compared with the prior art, the asphalt pavement material disclosed by the invention has a physical adsorption interception effect and a chemical purification effect at the same time, and the purification effects on suspended matter pollutants, heavy metal iron pollutants, heavy metal lead pollutants, biochemical pollutants, total nitrogen pollutants and total phosphorus pollutants are remarkably improved.
本发明涉及净化径流污染物的多孔赤泥沥青路面材料及其制备与应用，沥青路面材料包括沥青、赤泥及级配集料，沥青与赤泥的体积比为1:(0.3‑0.4)，沥青与赤泥的质量之和与级配集料的质量比为(0.04‑0.06):1；制备时，先将沥青加热熔融，并分别将赤泥及级配集料加热干燥；再将沥青、赤泥及级配集料混合均匀并在模具中用击实仪击实，之后静置，即得到沥青路面材料试件；将沥青路面材料铺设于道路上，对透过材料的道路雨水径流污染物进行净化。与现有技术相比，本发明沥青路面材料同时具有物理吸附拦截作用及化学净化作用，对于悬浮物污染物、重金属铁污染物、重金属铅污染物、生化类污染物、总氮污染物和总磷污染物的净化效果有显著提升。
