Embodiment Construction

[0040] The paving body of the present invention is a paving body used for laying and fixing on a road bed or a road base. The paving body is formed by applying a paint on the surface of a substrate, that is, a paving matrix. The paint is a heat-insulating paint that can suppress the rise in road surface temperature. Here, the so-called "road bed" refers to a ground that is dug downward and flattened to make it firm when paving a road. In addition, the term "roadbed" refers to a portion where gravel and sand between the paving surface and the road bed are fully laid.

[0041] In addition, as the paving matrix (substrate) on which paint is applied on the surface, there are various substrates, for example, asphalt-based asphalt pavement such as densely graded asphalt pavement, open graded asphalt pavement, discontinuously graded asphalt pavement, gravel asphalt mastic pavement, etc. Pavement; cement concrete pavement; resin-based pavement; brick pavement using flat bricks for s...

Abstract

The invention relates to a pavement body which is laid and hardened on a road floor or a roadbed. The pavement body has a paving matrix. Coating materials are coated on the surface of paving matrix. The coating materials have at least black pigment containing perylene, white pigment and pigment development.

Description

technical field [0001] The present invention relates to paving bodies. More specifically, it relates to a paving body for suppressing a rise in temperature of a road surface. Background technique [0002] In recent years, a large number of heat island phenomena have occurred in which the aboveground temperature in urban areas is higher than that in the surrounding areas of urban areas in summer. The reason for this is said to be that the heat accumulated in the asphalt pavement and other paving bodies on the road surface is radiated at night, so that the temperature cannot be lowered. If such a heat island phenomenon continues, not only will the ambient temperature on the earth rise, but it will also be difficult for humans to fall asleep at night. As a solution to the heat island phenomenon, in order to suppress the temperature on the road surface, a water-retaining road surface in which a porous paving body is filled with a filling material such as cement slurry with exc...
