Description

MATHOD FOR ROAD CONSTRUCTING USING WATER PERMEABLE CONCRETE AND PERMEABLE EXPOSED COLOR AGGREGATES PAVEMENT}

The present invention relates to a floor construction method using water-permeable concrete, and in particular, the road paving using water-permeable concrete is easy to drain water, as well as to expose the pavement of the road by exposing to the top when paving the road using color bean gravel. The present invention relates to a method for constructing soybean gravel exposure packaging using permeable concrete and colored soybean gravel.

Generally, the water-permeable paving method, which is used to preserve the underground ecosystem, promote the growth of urban street trees, and pursue pleasant walking during the rainy season, is typically a method of paving with water-permeable asphalt or water-permeable concrete. These methods are widely used for paving sidewalks, driveways, plazas, parking lots, and the like.

In other words, due to the acceleration of urbanization, the area where roads and ground surfaces are paved with asphalt and concrete is increasing. Rainwater that falls on paved roads and roofs of buildings does not penetrate underground, but flows directly into rivers and seas through urban rivers and sewers. Therefore, during rainfall, a sudden increase in quantity may occur and cause urban flooding. In addition, since much of the side of urban rivers are paved with impermeable concrete or asphalt and are parked, it is not easy to permeate plants, which makes it impossible to plant plants, and contaminates water and soil pollution, and causes ground subsidence. A problem occurred.

As a method of preventing desertification of the city, a method of paving road surfaces and ground surfaces with permeable concrete having high permeability has been used. Water permeable concrete is concrete that forms continuous voids using fine aggregates so that rainwater flowing along the surface of the concrete or stagnating can be easily penetrated underground. Since its introduction in Korea, it has been widely used not only for sidewalks but also for roadways.

The water-permeable concrete is to help the rainwater penetrates into the ground through the gap between the aggregate and the aggregate, to help plant growth such as roadside trees, rain or rain and rainy season during rainy season soaks into the ground and stored in the soil and rivers There is a trend to prevent the flooding and to have a comfortable advantage for pedestrians because rainwater does not flow or flow on the sidewalks, so it is widely used in roads, sidewalks, and bicycle paths. This is due to the eco-friendly nature of permeable concrete, which has several advantages such as increasing the groundwater content of the soil and adjusting flood capacity.

Conventional floor construction method using water-permeable concrete is a clean up step of arranging the base layer or auxiliary base and voltage, a mixing step of forming a permeable concrete pavement with aggregate, gravel and water, and a permeable concrete pavement on the base or auxiliary base layer And a permeable layer forming step of forming a permeable layer by voltage, and a finishing step of drying and curing the permeable layer.

However, the above-mentioned floor construction method using permeable concrete has a rough surface, which makes the walking feeling bad, and most of these permeable pavement materials are black, gray, and red, which are monotonous and artificially toned. There are disadvantages that are not suitable in terms of the landscape.

The present invention has been devised to solve the above-mentioned conventional drawbacks, and easy to drain water by paving the road using permeable concrete, as well as exposed to the upper road when using natural color soybean gravel road The purpose of the present invention is to provide a method for constructing soybean gravel exposure packaging using permeable concrete and colored soybean gravel that can beautify the paving.
