Water-permeable pavement structure and water-permeable pavement process
The invention provides a water-permeable pavement structure and a water-permeable pavement process, and belongs to the technical field of water-permeable bricks. The water-permeable pavement structurecomprises a surface layer which is a water-permeable brick and comprises the following raw materials, based on the weight of the surface layer being 1, in percentage by weight: 38-45% of concrete coarse aggregate, 30-35% of concrete fine aggregate, 18-22% of cement, 6-7% of water and 0.15-0.22% of powdery polycarboxylate superplasticizer; wherein the concrete coarse aggregate is particles with the particle size larger than 4.75 mm and not larger than 31 mm, and the concrete fine aggregate is particles with the particle size not larger than 4.75 mm; the concrete coarse aggregate and the concrete fine aggregate are aggregate obtained by recycling construction waste. The water permeable brick is prepared from the concrete regenerated from the waste garbage, so that the reduction of the wasteconstruction garbage is realized, the environment is protected, the energy is saved, the porosity is high, the water absorbability is strong, the water permeability is high, the compressive strengthcan reach 30 MPa or above, and the compressive strength is high.
本发明提供了一种透水铺装结构及一种透水铺装工艺，属于透水砖技术领域，透水铺装结构，包括面层，该面层为透水砖，包括以下重量份的原料：38～45％混凝土粗骨料、30～35％混凝土细骨料、18‑22％水泥、6～7％水，0.15～0.22％粉状聚羧基减水剂，重量比以面层重量为1计；其中，混凝土粗骨料为粒径大于4.75mm，不大于31mm的颗粒，混凝土细骨料为粒径不大于4.75mm的颗粒；混凝土粗骨料、混凝土细骨料来自于建筑垃圾再生得到的骨料；采用废旧垃圾再生而成的混凝土制备透水砖，实现了废旧建筑垃圾的减量化，环保节能，孔隙率高、吸水性强、透水性高，抗压强度可达30MPa以上，抗压强度高。
