Abstract

The invention discloses a drainage and noise reduction pavement construction method, and belongs to the technical field of pavement construction. The construction method includes the following steps:a step of lower bearing layer checking and processing, namely the step of performing detection and evaluation on the water seepage situations of a lower bearing layer of an asphalt pavement, and performing preliminary perfusion sealing on detected crack weak parts; a step of the distribution of a waterproof layer, namely the step of performing emulsified asphalt distribution on the surface of a middle surface layer so that a waterproof bonding layer can be formed; a step of the mixing of a drainage asphalt mixed material, namely the step of mixing the drainage asphalt mixed material through mixing equipment; a step of the transport of the drainage asphalt mixed material, namely the step of transporting the mixed drainage asphalt mixed material to a construction site; a step of the paving of the drainage asphalt mixed material, namely the step of paving the drainage asphalt mixed material on the surface of the waterproof bonding layer through a paving machine; and a step of the compaction of the drainage asphalt mixed material, namely the step of compacting the paved drainage asphalt mixed material so that a drainage asphalt upper surface layer can be formed. Therefore, the problemsof poor noise reduction and drainage effects of existing pavements can be solved.

Description

technical field [0001] The invention relates to the technical field of road surface construction, and more specifically, it relates to a drainage and noise reduction road surface construction method. Background technique [0002] Pavement refers to a layered structure that is paved with various road construction materials on the road subgrade and directly bears the load of vehicles. A good-quality pavement should have sufficient strength and good stability, and its surface should meet the requirements of smoothness, compactness and anti-skid. [0003] The Chinese patent with application publication number CN109629365A and application publication date of April 16, 2019 discloses a road construction method, including clearing the road surface and dividing the construction reference line; paving asphalt concrete on the The cleaned road surface; the asphalt concrete paved on the road surface is compacted with a road roller; the compacted asphalt concrete is detected.
