Description
Technical field
The invention belongs to sponge urban infrastructure technical fields, and in particular to a kind of road surface knot for sponge city
Structure.
Background technique
The construction in sponge city, it is important to can absorb water, permeable " sponge in city ".City sponge depends on city sea
Continuous " matter " and " amount ".Expand metropolitan sponge amount, is the key that one of sponge urban construction.If urban area will be accounted for
About 30% Hard base layer (road, square etc.) is changed to can be permeable, then, the soil layer below these Hard base layers is just
Rainwater can be obtained, the cavernous body in city can be become, can increase 30% cavernous body in city, just so as to improve city soil property.
Nowadays in the construction of urban road, the construction of surface layer is the hard surfacing of cement or pitch compacting, hard road
The laying in face is difficult in the arriving in rainy season effectively by rain penetration into underground, and there is a large amount of ponding on road surface, influences
Pedestrian passes through, and especially in the driving process of vehicle, will increase braking distance, and pavement reflecting when night running is easy to happen thing
Therefore.
Summary of the invention
The present invention solves the technical problem of：A kind of pavement structure for sponge city is provided, it is existing to solve
