Drainage asphalt pavement with replaceable transverse drainage hose

Abstract

The invention relates to the technical field of pavement drainage, and discloses a drainage asphalt pavement with a replaceable transverse drainage hose. The drainage asphalt pavement comprises a large-gap permeable asphalt concrete surface layer, a modified emulsified asphalt bleeding sealing layer, an asphalt mixture middle-lower surface layer, a graded broken stone sealing layer, a bonding layer and a base layer from top to bottom, a transverse drainage cutting groove is formed in the asphalt mixture middle-lower surface layer, and a plurality of layers of permeable drainage pipe sets are arranged in the transverse drainage cutting groove. By optimizing the transverse drainage of the pavement and adopting the drainage pipe group capable of being replaced for multiple times, when the drainage pipe group is blocked, the function of the drainage pipe group can be restored to the beginning of traffic through replacement, the function maximization of the transverse drainage capacity of the pavement in the whole life cycle of the pavement is ensured, and the service life of the water seepage function of the whole drainage pavement is prolonged; and the drainage pipe group is convenient and quick to replace, low in laying cost and simple in process, and can meet the requirements of current elevated or ground drainage asphalt pavement newly-built projects.

Description

technical field [0001] The invention relates to the technical field of pavement drainage, in particular to a drainage asphalt pavement with replaceable lateral drainage hoses. Background technique [0002] With the construction of sponge cities in major cities across the country in full swing, drainage asphalt pavement technology, which is the core technology of the sponge city road industry, plays an even more important role in urban road construction. Its use is not limited to elevated roads, but on ground roads, sidewalks, Park trails, fitness trails and other locations have also been applied to a greater extent. The drainage pavement drains rainwater into the roadside drainage wells through horizontal drainage. When the road surface is wide laterally, the horizontal drainage of rainwater only by the lateral gaps in the pavement cannot meet the actual needs of rainy days. The local rainwater cannot be drained away in time. It has seriously affected the performance of the...
