Description

A permeable concrete composition having high strength and durability for eco-friendly elastic pavement and eco-friendly method for elastic pavement}

The present invention provides a high-strength and high-durability permeable concrete composition for eco-friendly elastic packaging capable of providing an eco-friendly elastic packaging of high strength and high durability, and an eco-friendly elastic packaging method using the same. About.

In general, children's playgrounds, promenades, sidewalks, around buildings, welfare facilities for children and the elderly, sports facilities, and bicycle paths are paved with elastic pavement materials to enhance the comfort and health of pedestrians so that they can feel the softness of the soil. have.

In this case, conventionally, elastic pavement has been made in the form of installing an elastic pavement material on the general concrete road pavement surface. As shown in FIG. 1, the conventional elastic pavement is coated with a primer on the surface of a general concrete road pavement, and then an elastic packaging material containing 85 to 90% by weight of an elastic rubber chip and 10 to 15% by weight of a binder is added. It has been constructed by mixing and installing.

However, such an elastic pavement method penetrates into the voids of the elastic pavement material during rain or snowfall, and the infiltrated water stays on the surface of the general concrete road pavement, so if the temperature is below freezing in winter, the strength is lost due to freezing and thawing of the concrete. And there was a problem in that the bonding force between the elastic packaging material and the general road pavement is lowered, causing the elastic packaging material pavement surface to rise. In addition, in terms of manufacturing cost and recycling, the elastic rubber chip has a risk that harmful substances may be leaked because most of the cases are recycling of waste rubber other than natural materials. In addition, since the elastic rubber chip reflects heat due to the nature of the rubber, it reflects radiant heat from the sun, thereby increasing the heat of the road surface.

In order to solve this problem, after performing a pavement of an openness type in which rainwater penetrates below the roadbed, a permeable concrete layer is formed on the pavement surface, and the top surface of the permeable concrete layer is environmentally friendly. Cork material elastic packaging was installed.

These elastic packaging materials made of cork material provide excellent cushioning with good flexibility, elasticity and compression recovery, and are harmless to the human body and are eco-friendly. However, due to the different shrinkage rates from the water-permeable concrete layer, the adhesive strength is reduced by shrinking and relaxing each according to temperature. There was still a phenomenon that the surface of the elastic packaging material was lifted due to deterioration and gaps. In addition, the low specific gravity, weak strength and durability of the natural cork itself is a situation in which the problem of lowering the strength and durability of the final elastic packaging material still remains.
