Preparation method of ecological pervious concrete pavement
The invention relates to a preparation method of an ecological permeable concrete pavement. The method comprises the following steps: paving a bottom layer, rolling the paved pavement to compact a pavement soil layer, and paving fine gravels on the soil layer; and paving a concrete base layer, namely preparing materials of the concrete base layer: mixing and stirring all the materials, namely double-size-fraction coarse aggregate, Portland cement, a stabilizer and water to obtain a base layer material A, then paving the base layer material A above the fine gravel layer, rolling the concrete base layer to enable the surface of the concrete base layer to be compacted and flattened, performing natural drying for 30-40 minutes, and finally, paving a cobblestone layer on the concrete base layer. According to the preparation method of the ecological water-permeable concrete pavement, by arranging the concrete base layer, the water-permeable concrete structure layer and the water-permeable concrete surface layer, the problem that the strength of the ecological water-permeable concrete pavement is affected due to large porosity is effectively solved, the compressive strength, the breaking strength and the durability of the pavement are enhanced, and the water permeability of the pavement is not affected.
本发明涉及一种生态透水混凝土路面制备方法，包括以下步骤：底层铺设，将铺设路面进行碾压，使路面土层被压实，再将细砾铺设在土层上方；混凝土基层铺设，准备混凝土基层材料：双粒级粗骨料、硅酸盐水泥、稳定剂和水，将所有材料混合搅拌后制得基层料A，然后将基层料A铺设在细砾层上方，并对混凝土基层进行碾压使之表面被压实平整，使之自然干燥30‑40min，最后在混凝土基层上方铺设鹅卵石层。该生态透水混凝土路面制备方法，通过混凝土基层、透水混凝土结构层和透水混凝土面层的设置，有效的解决了生态透水混凝土路面因孔隙率大导致强度受到影响的问题，增强了路面的抗压、抗折强度及耐久性，也不会影响路面的透水性。
