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.

Embodiment 1

[0042] Embodiment one: a kind of permeable asphalt pavement, such as figure 1 , comprising an asphalt pavement body 1, the asphalt pavement body 1 sequentially includes a soil base 2, a cushion layer 3, a base layer 4 and a surface layer 5 from bottom to top, wherein the base layer 4 is a cold-recycled stabilized gravel layer of asphalt pavement cement, and the asphalt pavement body 1. Sand-based permeable curbstones 11 are respectively provided on both sides.

[0043] like image 3 , a water-resistant layer 6 is arranged on the cushion layer 3, and the water entering the interior of the asphalt pavement body 1 is discharged laterally along the water-resistant layer 6, and a stress-absorbing layer 12 is arranged at the bottom of the cushion layer 3, and the stress-absorbing layer 12 is a rubber asphalt stress-absorbing layer. Layer 12.

[0044] like figure 1 , one side of the soil foundation 2 is provided with a drainage ditch 7 for collecting water, and the drainage ditch ...

Embodiment 2

[0048] Embodiment two: a kind of construction method of permeable asphalt pavement, comprises the following steps:

[0049] Step 1: Mix asphalt mixture

[0050] 1. Selection of mixing machinery: The mixing equipment adopts a fully automatic intermittent asphalt mixing plant with self-recording function, equipped with dust removal equipment with excellent performance and a device for detecting mixing temperature;

[0051] 2. Setting up of the mixing plant: the asphalt mixing plant shall complete the leveling and hardening of the site, the construction of transportation roads, the installation of water and electricity facilities, and the overlapping of the asphalt mixing plant as soon as possible. The asphalt in the material yard is stored in a sealed manner according to the type and label. Various mineral materials are piled up according to the category and must not be mixed. The filler is stored in storage tanks and must not be exposed to moisture. Good drainage facilities are...

Abstract

The invention discloses a water permeable asphalt road surface and a construction method thereof. The water permeable asphalt road surface comprises an asphalt road surface body, and the asphalt road surface body comprises an earth base, a cushion layer, a base layer and a face layer which are sequentially laid on the ground surface from bottom to top, a water insulation layer is arranged on the cushion layer, so that the water entering the interior of the asphalt road surface body is drained horizontally along the water insulation layer; a drainage ditch for collecting water is formed in one side of the earth base; a plurality of watering pipes which are connected with surrounding green belts are arranged in the drainage ditch; and water guiding pipes are arranged in the drainage ditch, and the water guiding pipes are connected to the gutter inlet. According to the water permeable asphalt road surface and the construction method thereof, water accumulating on the road surface is dispersed quickly, and the crack resistant ability of the road surface is improved by fully utilizing original discarded road surface materials, and the service life of road is prolonged.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a water-permeable asphalt pavement and a construction method thereof. 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 road...
