A permeable asphalt concrete structure and its construction method

Abstract

The invention relates to the technical field of road engineering and discloses a pervious asphalt concrete structure. The pervious asphalt concrete structure comprises a pervious asphalt concrete layer and a pervious cement concrete layer; an airflow dispersion layer is laid between the pervious asphalt concrete layer and the pervious cement concrete layer; an airflow air drying layer is laid at the bottom of the pervious cement concrete layer; a plurality of groups of step type air dispersion pipelines are arranged in the airflow dispersion layer in the transverse direction in the form of a straight line; the step type air dispersion pipelines extend into the pervious cement concrete layer to be in contact with the airflow air drying layer; air guide plates are in contact with both left and right edges of each group of step type air dispersion pipelines in the airflow dispersion layer; and the two adjacent groups of air guide plates form a triangle together with the pervious cement concrete layer. According to the pervious asphalt concrete structure, the problem that roads are slippery and icy because water on pavements cannot be effectively removed in rainy seasons and continuouscloudy and rainy weathers in the prior art is solved; the pavements can be rapidly air-dried to avoid slipping of pedestrians and vehicles so that traffic accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an air-dried pavement permeable asphalt concrete structure and a construction method thereof. Background technique [0002] In the continuous rainy season or winter continuous rainy weather, because the rain on the road is difficult to drain continuously, the road will be slippery or icy, which will increase the difficulty of driving, which is not conducive to the passage of pedestrians and vehicles, and will seriously cause traffic accidents. In the patent CN103233410A, a permeable asphalt cement concrete ground structure with heating function is disclosed, which dehumidifies and melts snow by using solar energy storage to generate heat, but in continuous rainy seasons or continuous rainy weather in winter, solar energy cannot supply power normally , the heating function fails, the road is slippery or icy, and in the existing road engineering, there is no structure that...
