Green ecological high-weather-resistance high-water-permeability pavement material and preparation method thereof
The invention discloses a green ecological high-weather-resistance high-water-permeability pavement material and a preparation method thereof. The permeable pavement material is prepared by the following steps: crushing iron tailings of 3-5 mm and 5-20 mm and construction waste, mixing the components with rare earth inorganic mineral glue, active slag powder and water, and stirring the mixture for3-5 minutes to pave the pavement, thereby forming the high-strength and long-life ecological permeable pavement. In the pavement material, the ratio (mass ratio) of the active slag powder to the rareearth inorganic mineral glue to the iron tailing slag (construction waste) coarse aggregate (the particle size is 3-5mm, or 5-20 mm) to the water is 1:(0.37-0.63):(3.5-4):(0.02-0.1); the 28 day compressive strength of the formed pavement material is 30-48.5 MPa, the breaking strength is 3-5 MPa, the permeability coefficient is 3.8-4.5 mm/s, the mass loss rate after 25 times of freeze-thaw cyclesis 0.4, and the compressive strength loss rate is 5.
本发明公开了一种绿色生态高耐候性高透水性路面材料及其制备方法，该透水路面材料由破碎至3‑5mm与5‑20mm铁尾矿和建筑垃圾，掺和稀土无机矿物胶、活性矿渣粉、水，搅拌三到五分钟后，即可进行路面摊铺，形成高强度、长寿命生态透水路面。此路面材料中，活性矿渣粉、稀土无机矿物胶、铁尾矿渣(建筑垃圾)粗骨料(粒径3‑5mm)(或粒径5‑20mm)、水的比例(质量比)为1∶0.37～0.63∶3.5～4∶0.02～0.1，形成的路面材料28天抗压强度30～48.5MPa，抗折强度3～5MPa，透水系数3.8～4.5mm/s，25次冻融循环后质量损失率为0.4，抗压强度损失率为5。
