PAVING-MATERIAL HAVING ELASTICITY AND WATER PERMEABILITY AND CONSTRUCTING METHOD OF PAVING-MATERIAL HAVING ELASTICITY AND WATER PERMEABILITY}

The present invention relates to an elastic permeable package and a method for packaging an elastic permeable package, and more particularly, using an elastic packaging binder that firmly couples the elastic chip of the lower permeable concrete pavement and the coupling between the elastic chips. The present invention relates to an elastic permeable package and an elastic permeable package packaging method that not only have excellent strength and durability, but also provide elasticity and permeability suitable for outdoor activities such as exercise or walking.

Pitched concrete generally refers to a pavement material that is designed to allow the flow of physical aggregates from the surface through the base to the subgrade to maintain proper porosity and strength by screening aggregates of 13 mm or less. In other words, the pitched concrete helps the rainwater penetrate into the ground through the gap between the aggregate and the aggregate to help the growth of plants such as roadside trees, and the rainwater soaks into the ground during heavy rains, heavy rains and rainy seasons, and is stored in soil. It prevents rivers and rivers from overflowing and prevents rain or water from flowing on the sidewalks, providing convenience and safety for pedestrians, bicycles, and vehicles.

Conventional permeable pavements include permeable asphalt concrete and permeable cement concrete. However, asphalt concrete has a problem that the road surface is severely deformed due to the high temperature in the summer and the voids of the road surface are blocked due to the viscosity of the asphalt, and cement concrete has a problem of falling down because of the rigid pavement.

In addition, the permeable concrete pavement layer was coated with an epoxy-based paint for the appearance of the surface, but in the case of slopes, it was more slippery than ordinary concrete, causing problems in terms of stability. When the peeling phenomenon occurs, and fine dust in the air gap, etc., there is a problem that excessive road surface maintenance costs are required to remove the water permeability.

Therefore, by improving the problems of the conventional permeable concrete, Korean Patent Publication No. 404679 (registered October 27, 2003) "Packing layer formed waste tire chip layer" has disclosed an improved permeable elastic package. . Specifically, the patent is "a water-permeable elastic package in which the filter layer, the crushed stone layer, the permeable concrete layer, the waste tire chip layer and the surface coloring layer are sequentially formed on the bottom layer (the road surface), and the filter layer has fine aggregate (sand) laid thereon. The crushed stone layer is formed by laying and crushing concrete crushed stone having a particle size of 25 mm or less, and the permeable concrete layer is cured by mixing and laying aggregate, cement, and admixture having a particle size of 5-13 mm with water. It has a compressive strength of 100kg / ㎠ or more and a permeability coefficient of 1x10 ^-3 cm / sec or more, the waste tire chip layer is a urethane resin as a binder for the waste tire chip having a particle size of 2.5-7mm and the waste tire chip 100g , 10-25 g of epoxy resin or acrylic resin and 1-4 g of inorganic pigment are formed by laying a mixture having a thickness of 10-20 mm. And the group lung permeability elastic package by spraying a urethane resin, an epoxy resin or an acrylic resin on the surface of the tire chipcheung, characterized in that the colored "in the claims.

However, in the case of the waste tire used in the present invention, the smell peculiar to the rubber lasted for a long time, and thus there was a limit in providing a pleasant environment for smell. The urethane resin, epoxy resin or acrylic resin binder used for bonding the waste tire chip was commercially available. As general resin binders in circulation, there has been a demand for a binder capable of further improving the bonding strength between materials to be bonded to maintain the strength and durability of the bonding layer almost permanently.

Therefore, the present inventors conducted research and development on the elastic permeable package in terms of raw materials and binders. As a result, the elastic chip is used as the main raw material of the upper layer of the elastic permeable package, instead of the waste tire chips, which have had a bad smell. The present invention has been completed by developing a binder which not only strengthens the bond but also strengthens the bond between the elastic layer and the water-permeable concrete layer thereunder.

The present invention has been made in order to solve the above-mentioned conventional problems, the present invention solves the odor problem generated in the waste tire chip, using the elastic chip instead of the conventional waste tire chip, and absorbs the shock when walking and convenient An object of the present invention is to provide an elastic permeable package and an elastic permeable package packaging method having elasticity and permeability that can be achieved.

In addition, the present invention is to develop a binder that can firmly bond between the elastic layer of the upper and the water-permeable concrete layer as well as the bonding between the elastic chips, the elastic permeable package and the elastic permeable packaging method excellent in durability and strength The purpose is to provide.

Hereinafter, the present invention will be described in more detail.

Styrene-based acrylic resin used in the present invention is a generic term for a polymer produced by polymerizing an acrylic monomer and is a milky white or transparent liquid having enhanced adhesion through high viscosity. By evaporation of water, fine molecules of the acrylic polymer combine to form a colorless transparent film (layer), and are excellent in gloss, water resistance, pigment cyclization, aging resistance, fastness and weather resistance.

Styrene butadiene latex (SB Latex) is a synthetic rubber-based binder used to combine the pigment and the filler, and at the same time to give the adhesion, durability, etc., excellent wear resistance, heat resistance and good processability.

Waste rubber chips and waste urethane chips are reclaimed rubber chips made by collecting and reprocessing waste rubber and waste urethane used in various products. They are excellent in ozone resistance, cold resistance, heat resistance and solvent resistance, and have good color stability. It is widely used as a substitute for elastic packing material, which is a polyurethane material, which is somewhat expensive as synthetic rubber.
