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 layer structure, and each layer shares its role.

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, and the surrounding environment including homes is often polluted.

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 an elastic pavement layer by packaging the whole using chips is used.

In particular, in recent years, by using a chip of various colors in the elastic pavement layer, a method of forming a pattern or a shape of a specific pattern to improve aesthetics or various signs or signs, as well as road signs have been used.

However, when the entire surface is packaged using waste tire chips, recycled rubber chips or curable urethane chips, the average hardness of the waste tire chips, recycled rubber chips or curable urethane chips is 65 degrees or less, so that the packaging layer is elastic. It is too high to be ergonomically elastic flooring material, and to solve this problem, it is used to manufacture materials with high hardness by increasing the amount of bicarbonate, but the specific gravity is high, the tensile strength is weak, the discoloration is good, and the adhesion is remarkably decreased. There was a disadvantage that the durability is lowered.

In addition, since the average hardness of the thermoplastic polyurethane chip or EPDM chip is more than 75 degrees, the pavement layer constructed of the thermoplastic polyurethane chip or the EPDM chip has excellent tensile strength and adhesive strength and is durable but needs elasticity such as a children's playground. As a flooring material, there were disadvantages.

Therefore, the object of the present invention can solve the problem of discoloration of the surface, it is possible to use a small amount of expensive colored chips can be carried out the whole coloring at a low cost, excellent durability and harmful to the human body by the addition of ocher The present invention provides a method of constructing a functional elastic pavement layer, which can obtain an environment-friendly effect in which a large amount of far infrared rays are emitted.

In order to achieve the above object as well as other objects that can be easily achieved 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 In the method of constructing an elastic pavement layer using mono chips, waste tire chips, or recycled rubber chips, the base layer is first laid with waste tire chips or recycled rubber chips which are inexpensive and have excellent elasticity and tensile strength. After forming, secondary laying with a high hardness polyurethane ocher resin chip or EPDM (Ethylene Propylene Diene Monomer) ocher chip having excellent adhesion and tensile strength to form an upper layer and hardening by compacting with a constant temperature roller. It is possible to solve the problem, and it is possible to use a small amount of expensive colored chips, so that the whole coloring can be performed at low cost. Was, the durability is excellent and the loess is added is not harmful to the human body was invented a large amount of far-infrared emission that is environmentally friendly in the elastic pavement construction method.

The method of constructing the elastic pavement layer of the present invention is inexpensive on the base layer, and is primarily laid with waste tire chips or recycled rubber chips with excellent elasticity, but only to the inside of the left and right sides of the construction surface is installed up to about 10 cm inside, and the adhesive strength is high. High-strength polyurethane ocher resin chip or EPDM ocher chip with high tensile strength, and the secondary laying of the entire construction surface including the base layer to form an elastic base layer and forming an upper layer with excellent adhesion and tensile strength. The upper and lower layers were integrated by hardening after compaction with a roller, and the upper and lower layers could be colored in various colors, and the adhesive elasticity and tensile strength were good.

In the method for constructing an elastic pavement layer according to the present invention, after digging soil to a certain depth from the surface, and after compacting process, the concrete is poured and cured, using polyurethane resin, EPDM chip, waste tire chip or recycled rubber chip. In the method of constructing an elastic pavement layer to be packaged, a low-cost, high-strength polyurethane having excellent adhesion and tensile strength is formed by first laying with waste tire chips or recycled rubber chips having excellent elasticity and tensile strength. It is characterized by secondary laying with ocher resin chip or EPDM (Ethylene Propylene Diene Monomer) ocher chip to form upper layer and hardening by compacting with constant temperature roller.

In addition, when the base layer is formed, only 10 cm of each of the left and right sides of the construction surface is laid to the inner side. It is characterized in that to prevent damage due to the adhesive force in advance.

In addition, the base layer uses waste tire chips or recycled rubber chips having a low hardness of 65 Hs or less, and the upper layer uses thermoplastic polyurethane ocher resin chips or EPDM ocher chips having high hardness of 75 Hs or more and tensile strength of 15 Mpa or more. Characterized in that.

First, the soil is dug to a certain depth from the surface, and after the compaction process, the concrete is poured and cured. However, if it is already paved with asphalt, cement concrete, sidewalk block, etc., the curved surface of the paved road surface is leveled horizontally, then cleaned and vacuumed through the gap with a vacuum cleaner. The primer is precisely applied and cured in an amount of 200 to 400 g / m 2.

Waste tire chips, recycled rubber chips and urethane binders pulverized to 2-3 mm on the surface of the urethane primer applied and cured were put in a stirrer at a ratio of 10: 2.5 (weight ratio), mixed for 3 to 4 minutes, and then Lay the ground floor. At this time, install only up to 10cm of the left and right sides of the surface of the construction surface, and about 10cm of each of left and right, which is not formed as an underlying layer when laying the secondary upper layer, is laid only by the upper layer, so that the base layer is weak. Prevent adhesive damage.

Immediately after laying the foundation layer, high hardness polyurethane ocher resin chips or EPDM ocher chips and urethane binders with excellent adhesion and tensile strength were added to the stirrer at a ratio of 10: 2.5 (weight ratio) and mixed for 3 to 4 minutes. By covering the entire installation surface by covering it on the first laid base layer, the underlayer of waste tire chip or regenerated rubber chip with low hardness is formed, and the high hardness polyurethane ocher resin chip with excellent adhesion and tensile force or The upper layer of the EPDM loess chip was formed, and by compacting with a constant temperature roller, the upper and lower layers were integrated, and the functional loess elastic pavement layer having excellent elasticity was obtained.
