Description of the Related Art With the aim of eliminating the heat island phenomenon, water-retentive pavement, the cross section of which is shown in FIG. 5, is being adopted in urban areas in order to suppress the temperature rise in the pavement (controlling the temperature rise in the road).

施行例としての値である。The water-retaining pavement shown in FIG. 5 is a pavement which suppresses an increase in road surface temperature due to evaporation of water stored in a special cement grout in the pavement. More specifically,
As shown in FIG. 5, a base layer 80 made of dense grained ascon having a thickness of 5 cm is formed on the upper part of the roadbed 100, and the base layer 8 is further formed.
0 is spread on the upper part of 0 so that the thickness after formation is 25 to 10 cm, and the grout 20b containing mineral fine powder having water retention property is injected into the voids of the open particle size asphalt mixture 20a and pressed. The paved surface 20 is formed. The thickness (dimension) of each layer is 1
It is a value as an enforcement example.

り兼ねない。However, in the technique shown in FIG. 5, the water-retaining grout 20b and the open-particle size asphalt mixture 20 are used.
There is no facility for supplying water to the water-retaining layer 20 composed of a, and water must be supplied only to rainwater to the water-retaining layer. Therefore,
When the amount of precipitation is small, water does not accumulate in the water-retaining layer (water-retaining layer 20), and the effect of suppressing the temperature rise due to evaporation (heat of vaporization) of water in the water-retaining layer 20 cannot be obtained. This can be a fatal drawback when implemented in the Japanese archipelago, which tends to be extremely hot in low precipitation years.

Since it is filled with water, the groundwater can be supplied to the water retention layer (for example, porous concrete) (2) through the vertical holes (4) (or the groundwater supply layer 6) by the capillarity. I can. In the water retention layer (2) to which the groundwater is supplied, the supplied groundwater evaporates due to heat (radiant heat that heats the pavement surface), robs vaporization heat, and suppresses the temperature rise of the road surface (2f). .

上昇を抑制することが出来る。Unlike rainwater, groundwater is supplied to the water retention layer (2) through the vertical holes (4) (or groundwater supply layer 6) without being affected by the climate, and the drawbacks of the prior art are solved. It It is also possible to store rainwater in the groundwater supply layer (6) when it rains. Then, when the amount of sunlight is large and the radiant heat is large, the stored rainwater can be supplied to the water retaining layer to suppress the rise in the road surface temperature due to the heat of vaporization.

維の採用が望ましい。Here, the water-retaining layer may contain not only water-retaining concrete or porous concrete, but also long-fiber material. This is because such a long fibrous material has water retention properties. Then, due to the capillarity of the long fibers, groundwater flows through the entire water retentive layer and is vaporized, whereby the road surface (2f) is cooled. In addition to this, since it is reinforced by the long fiber material, the strength of concrete is also improved. Further, since the paving technique does not use reinforcing bars, there is no need for fishing like reinforcing bar concrets for road construction in the future.
It is also possible to employ a short fibrous material instead of the long fibrous material. However, if short fibers are used, the capillaries may be cut in the middle, and water may not flow, so it is desirable to use long fibers.
