A rubber synthetic resin having flexibility or elasticity of about 0 to 90, preferably 50 to 70, such as room temperature curing urethane or elastic epoxy resin, is suitable.

ある。First, the adhesive side (
A foamed polyethylene sheet with adhesive applied to the back side and cut-out holes is positioned and glued in place, and then a resin such as thixotropic urethane resin or elastic epoxy is applied to the formwork using a trowel, squeegee, etc. The resin is applied so that it is sufficiently embedded in the hollowed holes, and when the applied urethane resin is in an appropriate hardening state, for example, in a semi-hardened state, for example in the B stage, when the sheet of the formwork is removed, the formwork A protrusion is formed by hardened resin in a hollow hole having a predetermined shape. Further, a concave portion is formed by a portion other than the hollow portion. In this case, the reason why the formwork is removed when the urethane resin is in a semi-cured state is because if the curing progresses any further, when the formwork is removed, there is a risk that the foam sheet for the formwork will tear and a portion will remain on the urethane resin side. It is.

要がある。In the above construction method, when the resin is embedded in the window frame and cured, the urethane resin bites into or penetrates into the gaps in the rubber chip layer in the underlying elastic layer consisting of vulcanized rubber chips and a binder, resulting in what is called an anchor.
Effective and has strong adhesion. For this purpose, the resin needs to have appropriate thixotropy so that it can be applied up to the height of the mold and can also slightly penetrate into the rubber chip layer.

This is applied to improve the surface properties of the protrusions, for example, it can give secondary properties such as durability, color, and mattness to improve appearance, durability, and anti-slip properties. .

ーフェスを行うことが可能である。Furthermore, if the protrusions are worn down or worn out due to long-term use of the elastic pavement, after cleaning the surface appropriately, use the formwork as described above to remove urethane. By applying resin, peeling off the mold when the urethane resin is in a predetermined semi-hardened state, and then hardening the urethane resin, new protrusions can be provided. Therefore, construction can be carried out easily and inexpensively, and surfacing can be carried out easily.

った相乗効果となる。In the present invention, the reason why the conventional elastic reinforcement material slips is that the water in the voids in the rubber chip layer is pushed out to the surface by the stepping pressure of shoes, creating a wet surface.
If the water is pushed out, the water will not reach the surface of each protrusion, and the concave areas other than the protrusions have good drainage due to the voids, so the surface of the protrusions will always be dry. Moreover, this creates a synergistic effect when combined with the anti-slip effect of the individual protrusions themselves.

In addition, the protrusions are mixed with various pigments to become colored urethane rubber, or appropriately colored with the above-mentioned top coat layer, and further provided with other surface properties, such as matte properties, It can be finished to a beautiful surface.

Obtain an elastic pavement. The reason why conventional elastic reinforcement materials slip is that water in the voids in the rubber chip layer is pushed out to the surface by the foot pressure of the shoe, creating a moist surface. If there is a protruding layer, even if water is pushed out, it will not reach the surface of the protruding layer, and the concave areas between the protrusions and the water-permeable elastic layer underneath will allow water to be separated easily. The surface of the protrusion layer is always in a dry state, and combined with the anti-slip effect of the individual protrusions themselves, this creates a synergistic effect, achieving excellent anti-slip properties.

In addition, by applying a top coat layer, the protrusions can be given various surface properties, such as greater durability, color, mattness, etc., and the protrusions can have their surface properties selected appropriately. It can be finished with a beautiful surface.
