Problems solved by technology
[0004] The purpose of the present invention is to address the deficiencies in the prior art, to provide a curb stone of assembled self-draining asphalt pavement and its construction method, which has the effects of good drainage of the road surface, stable driving on the road surface, and satisfying the separation function, etc., and solves the existing problems. The slow drainage of the curb stones in the technology leads to the soaking of the road surface, the extrusion of the water in the asphalt pavement layer by the vehicle load affects the service life of the asphalt pavement, and the connection of the curb stones by plastering cement mortar is easy to cause cracks in the joint joints, which is not conducive to drainage other difficult questions

The invention relates to the technical field of curb stone construction, and discloses a curb stone of an assembled self-draining asphalt pavement and a construction method thereof. The curb stone includes an impermeable base plate and side stones, and the base plate is provided with pores along the upper surface of the curb stone longitudinally distributed The permeable layer of the structure, the height of the upper surface of the permeable layer is lower than the height of the upper surface of the side stones to form a diversion corner for converging road surface water. The reserved holes run through the installation surface at both ends of the curb, and the reserved holes are provided with soft permeable pipes, and the vertical and horizontal flowing water infiltrated into the permeable layer flows into the soft permeable pipes and is discharged. The curb stone of the present invention has the effects of automatic and rapid drainage of road surface water, effective removal of accumulated water inside the asphalt pavement layer, and stable connection and installation. The construction method of the invention is simple and convenient, and the drainage effect of the asphalt pavement constructed by using the curb stone is good.
Description
technical field [0001] The invention relates to the technical field of curb stone construction, in particular to a curb stone for an assembled self-draining asphalt pavement and a construction method thereof. Background technique [0002] Curb stones are strip structures that separate road surfaces and shoulders in road engineering, such as figure 1 As shown, the separation of the asphalt pavement layer and the road shoulder by the curb is beneficial to the respective division of labor between the pavement and the road shoulder on the road. Asphalt pavement is widely used in road engineering because of its good driving feeling and fast maintenance speed. The road shoulder is located on the outer edge of the roadway and the edge of the roadbed, and the road shoulder has a certain width of the belt structure, including hard shoulders and soil shoulders. The role of the shoulder is mainly to protect the stability of the roadway, provide lateral margins for driving safety, and...
