Abstract

The invention relates to the technical field of concrete, and particularly relates to a porous pavement system and a construction method thereof. The porous pavement system comprises cement stabilized gravels, base layer concrete and surface layer concrete, the preparation raw materials of the cement stabilized gravels comprise a dry material and water, and the dry material comprises the following components in parts by weight: 140-160 parts of cement, 180-200 parts of aggregate chips and 1400-1600 parts of coarse aggregate; the preparation raw materials of each cube of base layer concrete comprise: 360 kg of cement, 850-1300 kg of recycled coarse aggregate, 205-820 kg of slag and 138-152 kg of water; the preparation raw materials of each cube of surface layer concrete comprise: 400 kg of cement, 144-176 kg of recycled coarse aggregate, 1025-1845 kg of slag and 143-157 kg of water. The porous pavement system has proper strength on the whole, and the permeable rate is still 100% after use of 7 months.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a permeable pavement system and a construction method thereof. Background technique [0002] Cement-stabilized crushed stone (hereinafter referred to as water stabilized) uses graded crushed stone as aggregate, uses a certain amount of cementitious material and sufficient mortar volume to fill the gaps in the aggregate, and paves and compacts according to the principle of embedded extrusion. Its compaction is close to compactness, and its strength mainly depends on the principle of interlocking and locking between crushed stones, and at the same time, there is enough mortar volume to fill the voids of aggregates. Its initial strength is high, and its strength increases with age to quickly form a board, so it has higher strength, better impermeability and frost resistance. The amount of water-stabilized cement is generally 4%-5% of the mixture, and the 7-day unconfined compressi...
