Description

Construction method of permeable multilayer packaging using waste tire rubber chips, silica sand, EPDM chips and aggregates {Double layer paying material which is used by recycle tire, grit, and colored rubber.}

The present invention relates to a method for constructing a permeable multi-layer pavement using waste tire rubber chips, aggregates, silica sand, EPDM chips and polyurethane binders. Permeable multi-layer packaging material installed and packaged directly on top of the permeable multi-layer packaging material using waste tire rubber chips, silica sand, and aggregates to reduce unnecessary construction materials and provide high permeability with permeable multi-layer structure with permeable voids on the surface and base. It is about a method.

In general, in Korea, a base layer should be formed by concrete, etc. by laying elastic packing materials. If there is no base layer, concrete pavement is laid at a thickness of 150 m / m or more and the surface layer packing material is constructed.

When the elastic pavement is laid and cured on the concrete as described above, the surface layer is the elastic pavement material and the base layer is the concrete layer, and the rainwater is permeated from the surface layer and the water layer penetrates into the concrete layer. The separation of materials caused by the change caused the separation of substrate and surface, which affected the additional construction and safety.

Therefore, in recent years, permeable concrete helps the rainwater seep into the ground through the gap between the aggregate and the aggregate to help the growth of plants such as roadside trees, and during the heavy rain, heavy rain and rainy season, the rainwater seeps into the ground and is stored in the soil. Due to the advantages of preventing flooding of rivers and the accumulation of rainwater on the sidewalks, permeable concrete is becoming more popular.

However, permeable pavement for permeable pavement for existing roads, sidewalks, bicycle paths, and jogging courses is used for permeable asphalt concrete and permeable cement concrete. There are many disadvantages such as deformation of packaging materials.

Therefore, in order to solve the above problems, the present invention is used to install a permeable multilayer packaging material using waste tire rubber chips and silica sand, aggregate, which is a multilayer packaging material structure directly on the ground or aggregate layer, such as a concrete layer without the need for a base layer Therefore, it is to provide a construction method to increase the permeability by removing the concrete layer, which is a double foundation, to conserve ground water and to recycle resources to provide safety and convenience.

In order to achieve the above object, the present invention, in the method for constructing the elastic packaging material, the surface of the aggregate to be blended in the process step of stopping the ground to the construction of the elastic packaging material and the nonwoven fabric coating process step and the elastic packaging material on the suspended ground Treatment step and the step of blending the surface-treated aggregate, waste tire rubber chip, silica sand, polyurethane binder and the process step of laying the blended compound to about 50-120m / m thickness on the ground and the formulation The process step of combining color EPDM rubber chip, waste rubber chip, and recycled urethane chip into fine sand and compounding machine and laying it on the formed base layer and compacting the surface layer installed on the base layer with thermal roller. And through the process step of curing the packaging material with the thermal treatment at room temperature, without the concrete layer or ascon layer on the ground It is to achieve the purpose by the construction method of permeable multilayer packaging material using waste tire rubber chips, silica sand, aggregate.

Hereinafter, described in detail with reference to the accompanying drawings.

1 is a process road showing the construction method of the present invention, the present invention is formed of a permeable multilayer packaging material that is a base layer (2) and a surface layer (1) so that it can be used as an elastic packaging material for bicycle roads, inline skating rinks, and the like.

The permeable multi-layer pavement is a method of laying on the ground (4) or aggregate, unlike the conventional method of conventionally installed on concrete or ascon, the ground (4) to be constructed first, and then stop the flat process, the next step After applying the base material (2) on the ground (4) and the nonwoven fabric (3) to prevent ground subsidence and loss during permeation, the strength, durability and mutual adhesion of the aggregate (6) blended into the base layer (2). And a small amount of polyurethane binder, through the process step of treating the surface of the aggregate (6) in order to secure the maximum permeability (7) and increase the permeability rate, 20-40% of the waste tire rubber chip (5) and aggregate ( 6) 80-60% and 10-20% of silica sand (8) are blended with a polyurethane binder as an adhesive and laid on the ground (4) to which the nonwoven fabric (3) is applied. The thickness of the base layer (2) is about 50-120m / form m. At this time, silica sand prevents material separation and warping due to temperature changes in summer and winter.

When the surface layer is installed on the installed base layer (2), the color is not easily discolored by ultraviolet rays, and the color EPDM rubber chip 10 is prevented from warping due to heat of 80-90% of the surface layer as an elastic material that can harmonize with the surrounding environment. Fine sand (9) is blended at a rate of 10-20% and laid at a certain thickness.

Through the process of compacting and finishing the part installed by thermal roller to form the base layer (2) and the surface layer (1) and secure the flatness, durability, elasticity and permeability, it is cured at room temperature It is a method of constructing a permeable multilayer packaging material having a range.

Therefore, the packaging material of the present invention can be directly installed in a double structure consisting of a base layer and a surface layer to solve the groundwater depletion by increasing permeability and to ensure safety in rainy weather or in winter.

That is, the permeable multi-layer packaging material is a surface layer (1) is formed of a color EPDM rubber chip and sand can achieve a variety of colors, while ensuring the material separation phenomenon and safety, and at the same time the rain water that is permeated from the surface layer naturally. Permeability can be filtered to increase permeability.

The effects of the present invention described above can replace social indirect facilities such as bicycle paths, amusement facilities (inline skating rinks) by using permeable multi-layer pavement and construction methods using waste tire rubber chips, silica sand, EPDM chips, and aggregates. By using silica sand and recycled aggregates, the paving material, which is a multi-layer structure, is laid directly on the ground without the need for resource recycling and existing concrete layers. , Has the effect of increasing activity.

In addition, the four seasons are clear and the temperature difference is so severe that silica sand and sand are properly mixed to prevent warping of the packing material or material separation.
