Abstract

The invention provides a drainage curb stone, which relates to asphalt road drainage. The drainage curb stone comprises an impermeable main body, wherein a clamping groove is formed in the impermeable main body; a permeable concrete block is embedded in the clamping groove; the clamping groove is arranged in a length direction of the impermeable main body; a plurality of permeable blind holes are formed in the side wall of the clamping groove; each permeable blind hole is formed right above the permeable concrete block; and the port of each permeable blind hole is positioned on the external surface of the impermeable main body. The invention further provides an asphalt road with a drainage structure, wherein the asphalt road with the drainage structure comprises the drainage curb stone. According to the invention, the permeable concrete block is embedded in the impermeable main body and the plurality of permeable blind holes are formed right above the permeable concrete block, accumulated water on the upper surface of the asphalt road can permeate into the permeable concrete block via the permeable blind holes and stagnant water in the asphalt road can also transversely flow into the permeable concrete block; and rainwater gathered in the permeable concrete block can be drained in time so that rainwater inside and outside the asphalt road can be both drained in time to ensure the service life of the asphalt road.

Description

technical field [0001] The invention relates to asphalt pavement drainage, in particular to a drainage curb and an asphalt road with a drainage structure. Background technique [0002] Asphalt concrete is a porous medium with many pores. Rainwater will infiltrate into the pavement structure layer through the pores and cracks of the pavement. According to the formula calculation provided by "Code for Design of Highway Drainage" (JTG / TD33-2012), it can be seen that the amount of water permeated into the pavement structure per longitudinal meter of the 7.5m wide asphalt pavement in rainy days is 1.125m 3 / (d·m). It is difficult to drain so much stagnant water inside the asphalt pavement structure in a timely manner by evaporation alone. A large number of pavement damage surveys and use experience show that the water entering the pavement structure is the main cause of causing or accelerating pavement damage. [0003] Water-permeable fillers are often used to fill soil road sh...
