An asphalt pavement structure

Abstract

The invention discloses a bituminous pavement structure. The bituminous pavement structure comprises a bituminous pavement layer laid on the ground surface; gaps facilitating rapid leakage of rainwater are formed in the bituminous pavement layer; sand-based water permeable kerbs are arranged on the two sides of the bituminous pavement layer; the bituminous pavement layer is sequentially provided with a laying layer, a water stabilizing layer and a stress absorption layer from top to bottom; a water permeable surface layer is arranged below the bituminous pavement layer; a water permeable base layer is arranged below the water permeable surface layer; a pipe network used for collecting rainwater is embedded into the water permeable base layer; filter ditches are formed in the two sides of the water permeable base layer; the two ends of the pipe network are connected to the filter ditches; the filter ditches are internally provided with a plurality of watering pipes connected with a surrounding green belt; and water guide pipes are arranged at the two ends of the filter ditches and connected to rainwater openings. As the bituminous pavement layer is arranged, the pavement anti-cracking capacity is improved, pavement water damage and rutting are reduced, original waste pavement materials can be fully used, the service life of the pavement is prolonged, the rapid leakage function is achieved for accumulated water, and accumulated water on the pavement can be rapidly drained.

Description

technical field [0001] The invention relates to the technical field of municipal construction, more specifically, it relates to an asphalt pavement structure. Background technique [0002] Urban planning and construction must consider the impact on nature in every detail, not to mention breaking the natural system. When improving urban pavement drainage, priority should be given to retaining limited rainwater and more use of natural forces to drain water. [0003] Municipal construction projects generally use only the replacement of asphalt pavement in road reconstruction, and the excess water is naturally drained by the lateral slope. When the asphalt pavement is saturated with water, it cannot penetrate downward quickly, forming a large amount of water Water, when the temperature is low in winter, the stored water will freeze, making the road more slippery and even damage the paving bricks through volume expansion, resulting in wet and slippery roads and inconvenience for...

Problems solved by technology

[0003] Municipal construction projects generally use only the replacement of asphalt pavement in road reconstruction, and the excess water is naturally drained by the lateral slope. When the asphalt pavement is saturated with water, it cannot penetrate downward quickly, forming a large amount of water Water, when the temperature is low in winter, the stored water will freeze, making the road more slippery and even damage the paving bricks through volume expansion, resulting in wet and slippery roads and inconvenience for people to walk. To solve such problems, we cannot rely on natural evaporation or saturation from the top surface The method of dispersing should be carried out before causing water accumulation on the road.
