Embodiment Construction

[0027] See figure 1 . The recycled aggregate fully permeable concrete pavement structure provided by the invention includes a permeable cushion 2, a permeable base 3, a permeable surface 4, and a permeable cover 5 laid from bottom to top on the soil foundation 1; the permeable cushion 2. Natural crushed stone is used, the thickness of which is 100-200mm; the permeable base layer 3 is made of recycled aggregate permeable concrete, the maximum particle size of the aggregate is less than 16mm, and the laying thickness is not less than 150mm; the permeable surface layer 4 is made of recycled aggregate Permeable concrete, the maximum particle size of the aggregate is less than 16.0mm, the laying thickness is 90-120mm, and the water permeability coefficient is greater than the permeable cover layer; the permeable cover layer 5 is configured with natural aggregates such as hard, durable and clean granite For permeable cement concrete, the maximum particle size of the aggregate is les...

Abstract

The invention discloses a recycled aggregate total pervious concrete pavement structure and a construction method thereof. The pavement structure comprises a pervious cushion ply, a pervious base layer, a pervious surface layer and a pervious cover layer paved from bottom to top; the pervious cushion ply is made from natural gravels; the pervious base layer and the pervious surface layer are recycled aggregate total pervious concrete; and the pervious cover layer is pervious concrete prepared from a aggregate. The pavement structure disclosed by the invention is relatively good in water permeability and wear resistance.

Description

technical field [0001] The invention belongs to concrete pavement construction technology, in particular to a recycled aggregate fully permeable concrete pavement structure and a construction method thereof. [0002] technical background [0003] At present, the large-area pavement structure in the city lacks air permeability and water permeability, which has brought many negative impacts on the urban ecological environment, mainly including the fact that rainwater cannot penetrate the surface and return to groundwater, resulting in a decrease in the groundwater level; rainwater can only flow into the city through drainage facilities. Rivers, lakes and seas increase the burden on drainage facilities; they cannot exchange heat and humidity with the air, resulting in the "heat island phenomenon". Moreover, when there is water on the road, the road surface becomes slippery and easy to reflect light at night, which leads to traffic safety accidents and threatens people's travel s...
