Problems solved by technology

[0008] On the other hand, in the structure of Patent Document 2, a water-permeable hard pavement member is laid on the roadbed, and then the water-retaining slurry is dispersed and impregnated in the planar direction from the surface of the water-permeable hard pavement surface, and the paving work is extremely troublesome.
[0009] In addition, the inclination in the road width direction of the conventional surface drainage hard road surface adopts the same inclination for a certain distance from the center to both ends, and the inclination for the remaining distance is steeper than the above-mentioned inclination. For example, there are the following problems: even if the surface part adopts a water-retaining hard pavement or a water-permeable hard pavement, the excess water exceeding the water-retaining and water-permeable range suddenly flows into the sewer main pipe, exceeding the drainage capacity of the sewer main pipe. Possibility of reverse flow, which becomes an obstacle to the passage of bicycles or motorcycles on the side of the road

no. 1 Embodiment approach

[0038] figure 1 This embodiment shows that it is applicable to roads of so-called L traffic {less than 100 (units / day, directions)}, and further applicable to roads of B traffic {250 or more and less than 1000 (units / day, directions)}. In the hard pavement section of the hard pavement body 1, on the basis of laying the middle part 12, the surface part 11 formed by the material b having a water-permeable function is laid, and the roadbed 1a is formed by these two layers, wherein the middle part 12 is made of mixed It is composed of a porous aggregate mixture a of a porous material, namely coal cinder (CA) and a cement-like solidified material.

[0039] Coal slag is a substance that contains about 15% of finely pulverized coal in coal ash generated by high-temperature combustion (1300°C) in thermal power plants or steel plants, etc., and the particles after combustion are contained in the boiler The substances formed by agglomerating with each other, falling down and accumulati...

no. 2 Embodiment approach

[0057] image 3 The shown hard pavement body 2 forms the surface layer 21 by laying the porous aggregate mixture a to form the middle layer 22, and laying the surface layer material having a water-permeable function, that is, the water-permeable asphalt mixture b to form the surface layer 21. This point is different from the roadbed of the above-mentioned embodiment 1a is basically the same, and is a hard pavement body with water absorption and water permeability. Moreover, in this embodiment, a crushed stone roadbed c is provided under the middle part 22 formed by the porous aggregate mixture a to form the second middle part 23, and a porous material d not containing the mixture is arranged below it. And the base part 24 is formed, and the roadbed 2a is comprised by this. The porous aggregate mixture a is a mixture obtained by mixing at least a cement-based hardening material with cinders and compacted, and the surface material b is a water-permeable asphalt mixture. On the...

Abstract

The present invention provides a hard pavement body that drains well and retains a part of the water during rainfall to avoid the occurrence of a large amount of drainage. During sunshine, etc., the retained water is supplied to the surface layer, and water is sucked up from the road bed to lower the surface layer temperature. The middle layer (12) is formed by laying a porous aggregate mixture (a) made of mixing porous materials and cement-based solidified materials, and the surface layer (11) is formed by laying an asphalt mixture (b) having a water-permeable function on it, Thereby, the roadbed (1a) is constructed by the hard pavement body (1).

Description

technical field [0001] The invention relates to a hard pavement body, a construction method of the hard pavement body, and a form box for concrete, which use a porous mixture to improve water retention and water permeability. Background technique [0002] As a hard road surface having water retention and water absorption properties, the hard road surface disclosed in Patent Document 1 is known. The hard pavement described in this document is composed of a surface layer, a subgrade, and a road bed in order at least from the top, and the water-retaining cement slurry that retains water is filled in the gaps of the hard pavement layer made of open-graded asphalt to a predetermined thickness to make the surface layer become Water-retaining finish. The subgrade below is a water-retaining base layer thicker than the surface layer, and the base layer is made of aggregates having numerous pores that hold water, and a large amount of water is retained by the combination of the water...
