In general, road pavement is a road structure that is processed to enhance the protection and flatness of the road surface and to facilitate the passage of people and the driving of the vehicle. The road pavement is a multi-layered structure, and the floors share their respective roles.

The road pavement is classified into three types according to the material of the surface layer: bitumen (asphalt) pavement, concrete type pavement, and block pavement.The bituminous system pavement is composed of aggregates such as crushed stone which is solidified by asphalt or tar. It is called as asphalt pavement, tar pavement, etc., and currently occupies most of the roads around the world, and there are many kinds.

Concrete paving is concrete laid on the surface layer. In addition to concrete or ordinary concrete paving with wire mesh in concrete, reinforced concrete paving, prestressed concrete paving, etc., block paving includes stone, brick, cement, Various blocks such as wood and asphalt are laid on the surface layer, and they are not used for roadways but are used for sidewalks and plazas.

On the other hand, block paving is used to form a base layer by using sand after compaction of the base surface to give flatness, and then install a sidewalk block, rubber block, or the like, or install porous concrete.

However, the above method causes irregular settlement due to the loss of sand layer during rainfall or excessive outflow of permeate to a certain part, which leads to cracking, damage and settlement of the surface layer as well as a lot of manpower to install the block. And time is required, and since the block does not exactly match the width of the road, the block has to be cut and finished.

 In addition, since children's playground is the most important part to be considered, the floor surface should have good shock absorption to prevent safety accidents and should not be slippery. Playgrounds have become a breeding ground for various pests and pathogens, and not only are they reluctant to play on the playground, but sand often gets into the shoes or clothing, causing abrasions and dirty surrounding environments including homes.

Recently, in order to solve the above problems, a method of packaging the entire surface using polyurethane resin, EPDM (Ethylene Propylene Diene Monomer) chip, waste tire chip or recycled rubber chip is used. In this case, after the concrete is poured into the base layer and cured, a method of forming the absorbent pavement layer by using the chip as a whole and packing is used.

In particular, in recent years, by using chips of various colors in the absorbent pavement layer, a method of forming a pattern or a shape of a specific pattern to improve aesthetics or to make various signs or signs as well as road signs is used.

Conventional construction methods for forming a specific pattern or pattern is absorbent packaging polystyrene foam in a state in which a specific pattern is made using a polystyrene foam as shown in Figure 4, but cut the portions in which chips of different colors are wrapped After placing on the concrete surface to be packed in layers, only the parts corresponding to the same color are removed firstly, and then the polystyrene foam of the part to be packed in different colors is removed and the second method is used.

However, the above method is not only a risk of breakage when repeated use of polystyrene foam, it is not easy to make a pattern or shape of a specific pattern with polystyrene foam, and used polystyrene foam should be discarded, causing environmental pollution, etc. There was a problem, such as troublesome construction.

Accordingly, an object of the present invention is to provide a method of constructing an absorbent pavement layer into which a pattern or shape of a specific pattern is inserted, which is simple, convenient, and can shorten the packaging time. The present invention provides a method for constructing an absorbent packaging layer to obtain a clean absorbent packaging layer.

In order to achieve the above object as well as other objects that are easily expressed, in the present invention, by digging the soil to a certain depth from the surface, and after the compaction process to cast concrete to cure, polyurethane resin, EPDM (Ethylene Propylene Diene Monomer) In the method of constructing the absorbent pavement layer, which is packaged as a whole using chips, waste tire chips, or recycled rubber chips, and has a specific shape, made of soft synthetic resin, which has an inverted T-shaped cross section, and an adhesive is applied to the bottom of the support part. It is attached to the release paper, and the insertion hole is drilled at regular intervals on both sides of the support, and the boundary compartment is formed in the center of the support so as to protrude to the same height as the pavement surface. Squeeze and pack chips of different colors in each compartment It is simple and convenient, and it can shorten the packaging time, and it is possible to obtain the absorbent pavement layer with clear and clean interface of specific pattern or shape. It was easy to work flat and improved workability.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
