Road structure and construction method thereof

Abstract

The invention relates to the technical field of road structures, and provides a road structure which comprises a road body, curbs are arranged on the two sides of the road body, and drainage grooves are formed in the sides, away from the road body, of the curbs. The road body comprises a macadam base layer laid on the roadbed, a buffer base layer laid on the macadam base layer, a stabilizing layer laid on the buffer base layer, a flow guide layer laid on the stabilizing layer, a water permeable layer laid on the flow guide layer and a water permeable pavement layer laid on the water permeable layer, and the vertical height of the middle of the flow guide layer is larger than that of the two sides of the flow guide layer; drainage extensions are arranged on the two sides of the permeable layer, extend to the drainage grooves and extend to the side walls of the drainage grooves, and a cooling system is laid on the permeable layer. By means of the technical scheme, the problems that in the prior art, temperature rise of the road surface cannot be continuously and effectively controlled, the traffic comfort is affected, and road aging and deformation caused by high temperature cannot be fundamentally solved are solved.
