Construction method of long-service-life pass-through induced drainage pavement

Abstract

The invention discloses a construction method of a long-service-life pass-through induced drainage pavement. The construction method comprises the following steps: 1, preparing filtering materials of the pass-through water-induced pavement, including coarse aggregate, fine aggregate and modified bituminous mixture according to the weight ratio of 58.5 to 35.85 to 5.65, wherein the modified bituminous mixture comprises slaked lime, red mud and conjugate fiber according to the weight ratio of 58.5 to 35.85 to 5.65, and the conjugate fiber comprises wood fiber and basalt fiber according to the weight ratio of 1 to 2; 2, processing a substrate of the construction pavement; 3, arranging an adhesive layer or sealing layer which has the thickness of 0.1-0.2mm and the porosity of 30%; 4, arranging a substrate filtering material layer which is 0.05-0.15mm thick between a soil layer and a gravel layer of the substrate; 5, mechanically paving; 6, treating joints; and 7, maintaining the pavement. The construction method can obviously improve the adhering force, anti-cracking performance, tensile and water-damage resistance performance and noise reducing performance of the pavement, enhance the rainstorm resistance of the pavement, and reduce the influence of long-term rain storage on stability performance of bituminous concrete.

Description

Technical field: [0001] The invention relates to a construction method of asphalt pavement, in particular to a construction method of long-life permeable induced drainage pavement, which allows the rainwater remaining in the drainage surface layer to pass through the connected gaps in the surface layer and technically induces it to flow horizontally Flow and discharge the road surface. Background technique: [0002] At present, in the construction process of traditional non-permeable pavement, the waterproof and anti-seepage performance of the road surface is one-sidedly emphasized. This pavement completely blocks the natural rainfall from the soil layer and groundwater below the pavement, and the rainfall has to be discharged into rivers, rivers, rivers, etc. through the urban drainage system pipe network In surface water sources such as lakes and seas, this makes it difficult for urban groundwater sources to be replenished in a timely manner, which seriously affects the e...

[0002] At present, in the construction process of traditional non-permeable pavement, the waterproof and anti-seepage performance of the road surface is one-sidedly emphasized. This pavement completely blocks the natural rainfall from the soil layer and groundwater below the pavement, and the rainfall has to be discharged into rivers, rivers, rivers, etc. through the urban drainage system pipe network In surface water sources such as lakes and seas, this makes it difficult for urban groundwater sources to be replenished in a timely manner, which seriously affects the effective use of rainwater; at the same time, when it rains on impermeable ground, the rainwater is first discharged into the sewer through the drainage slope or surface ditch on the ground. Before entering the sewer, it has to go through a long distance of surface runoff to enter the urban underground drainage system. This process makes relatively clean rainwater dissolve into a large amount of urban surface pollutants. The secondary pollution generated in this runoff process passes through the city. Drainage into the surrounding surface natural waters, thus increasing the pollution of these natural waters
