Problems solved by technology

[0006] The impermeable pavement caused by the closed surface also makes it difficult for the surface plants used to adjust the microclimate in the city to grow. Some trees even die or fall due to lack of water in the root system, thus losing their ecological functions.

Abstract

The invention discloses a complete permeable compound type road surface structure. The complete permeable compound type road surface structure comprises a surface layer, a bonding layer, a grid layer, a base layer and a cushion layer which are arranged on a roadbed in sequence from top to bottom, wherein the surface layer is a permeable surface layer formed by permeable asphalt concrete; the bonding layer is a permeable asphalt bonding layer formed by asphalt; the grid layer is a glass fiber grid; the base layer is a permeable base layer formed by permeable cement concrete; the cushion layer is a permeable particle cushion layer formed by mixing one or more of graded broken stones, graded gravels and graded broken gravels; the complete permeable compound type road surface structure has the advantages of no joints of an asphalt road surface, small driving vibration, low noises, and easiness and convenience for maintenance, and also has the advantages of high strength of the cement road surface, long service life and the like; and on the other hand, the complete permeable compound type road surface structure has the characteristics of water permeability, ventilation and the like, rainwater can rapidly permeate and can be discharged into the stratums, a city ecological balance system is effectively kept, the load of city drainage facilities also can be relieved when the rainfall capacity is relatively great, so that the structure has the active meaning.

Description

technical field [0001] The invention relates to the technical field of road pavement structures, in particular to a completely water-permeable composite pavement structure. Background technique [0002] In urban construction, many cities use cement concrete and asphalt concrete to replace the original soil surface. For public places such as roads, sidewalks and non-motorized vehicles, they also like to use neat and beautiful stone plates or cement colored bricks. While improving traffic and road conditions and beautifying the environment, the closed surface also has significant adverse effects on urban ecology and climate. [0003] Among them, the closed surface is gradually hardened and covered by water-blocking materials, making it difficult for water to infiltrate. Precipitation quickly becomes surface runoff and enters rivers or underground drainage pipes, thus forming an ecological "artificial desert". [0004] The impermeable pavement caused by the closed surface lac...
