Asphalt pavement material for purifying road runoff pollution as well as preparation method and application of asphalt pavement material
An asphalt pavement material for purifying road runoff pollutants comprises asphalt, diatomite and graded aggregate, the volume ratio of the asphalt to the diatomite is 1: (0.33-0.35), and the mass ratio of the sum of the mass of the asphalt and the mass of the diatomite to the mass of the graded aggregate is (0.04-0.06): 1. The preparation method of the asphalt pavement material comprises the following steps: heating and melting the asphalt, and respectively heating and drying the diatomite and the graded aggregate; and uniformly mixing asphalt, diatomite and graded aggregate, compacting in a mold by using a compaction apparatus, and standing to obtain the porous asphalt pavement material. According to the present invention, the on-site purification of the runoff pollution can be achieved, the physical interception-chemical adsorption composite purification function is provided, the purification effect on the heavy metal pollutants such as copper, chromium, iron, total nitrogen pollutants and total phosphorus pollutants is significantly improved, the certain traffic load can be borne, and the good road performance is ensured.
一种净化道路径流污染物的沥青路面材料，所述沥青路面材料包括沥青、硅藻土及级配集料，所述的沥青与硅藻土的体积比为1:(0.33‑0.35)，所述的沥青与硅藻土的质量之和与级配集料的质量比为(0.04‑0.06):1。所述沥青路面材料的制备方法，包括以下步骤：将沥青加热熔融，并分别将硅藻土及级配集料加热干燥；将沥青、硅藻土及级配集料混合均匀并在模具中用击实仪击实、静置，即得到所述的多孔沥青路面材料。本发明可以实现径流污染的就地净化，同时具有物理截留‑化学吸附的复合净化功能，对于重金属污染物铜、铬、铁、总氮污染物和总磷污染物的净化效果有显著提升，又能够承受一定交通荷载，保证良好的路用性能。
