In this process, rubber chips are crushed into small pieces, the crushed chip pieces are mixed with a urethane binder, and the mixture is thermally cured. Forming a mat block, further slicing the created mat block to form a logo block having a desired design, crushing rubber chips into fine pieces, and crushing the crushed chip pieces with a urethane binder Mixing, paving a road or sidewalk with the mixture, further leveling the surface of the paved road or paved sidewalk, and binder before the paved road or sidewalk is cured The logo block is attached to a desired position on the paved road or paved sidewalk, and further, the paved road or paved walk A step of the logo block while heating to leveling the road surface of the pavement or paving sidewalks fixed to the road or sidewalk and the gist to include.

Description

  The present invention relates to the design and construction of an elastic pavement for roads and / or sidewalks, and in particular, the design is created separately and the created design is inserted into the paved road and / or the sidewalk during the pavement work. The present invention relates to an on-site construction process of an elastic pavement design including a process to perform.

  As shown in FIG. 1 and FIG. 2, the design and construction of elastic pavement usually requires separately preparing a formwork (hereinafter referred to as “formwork 15”) having a desired design 15 after the process of leveling the road surface during the pavement work. The mold 15 is inserted into the elastic pavement 10, the elastic chip material 17 of a desired color is introduced into the mold 15, the mold 15 is removed, and then the materials are cured. Is called.

  In this regard, the conventional design and construction process has several problems in that the formwork is separately prepared in advance and then removed at the construction site, and the complicated design process. There was a problem that it was difficult to produce a formwork.

  Therefore, the present invention aims to solve the above-mentioned conventional problems, and the object of the present invention is to use a formwork by directly inserting a design into a paved road or a sidewalk during paving work. It is to provide a process of constructing a design without any trouble.

  To achieve the above object, the present invention provides, as an exemplary embodiment, an elastic pavement design construction process including the following processes.

  The rubber chips are crushed into small pieces, the crushed chip pieces are mixed with a urethane binder, the mixture is thermally cured to create a mat block, and the created mat block is sliced to obtain a desired design. Forming a logo block.

  Crushing rubber chips into fine pieces, mixing the crushed chip pieces with a urethane binder, paving a road or sidewalk on the site using the mixture, and further leveling the road surface of the paved road or sidewalk.

  A binder is applied to the bottom of the logo block before the paved road or paved side is cured to place the logo block at a desired position on the paved road or paved side, and further, the paved road or paved side is heated. And fixing the logo block on the road or sidewalk while leveling the road surface of the paved road or sidewalk.

  According to the elastic pavement design construction process according to the present invention, a logo design created separately can be inserted on the paved road or paved sidewalk without using a formwork for on-site construction of the design. , Thereby simplifying the logo design insertion.

The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.
It is a perspective view which illustrates the conventional elastic paving process. It is a perspective view which illustrates the conventional process which constructs a design using a formwork in elastic pavement. It is a perspective view of the design used for the elastic pavement which concerns on this invention. It is sectional drawing which illustrates the process of constructing the design of the elastic pavement which concerns on this invention.

  Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, the exemplary embodiments are presented only for illustrative purposes, and those skilled in the art will recognize various embodiments. It will be readily appreciated that changes and modifications may be made without departing from the scope and true spirit of the invention. Accordingly, the true scope of the invention is defined only by the appended claims and equivalents thereof.

(First embodiment)
Hereinafter, an exemplary embodiment of the present invention will be described with reference to FIGS. 3 and 4.

  Rubber chips such as urethane rubber chips, ethylene propylene (EPDM) rubber chips, and waste tire rubber chips are used. After crushing rubber chips of a desired color into small pieces of 2 to 5 mm size, the crushed pieces are mixed with a urethane binder, and then the mixture is thermally cured to form a mat block. Next, the mat block is sliced to create a logo block or a design block (hereinafter referred to as “logo block” 30).

  In the case of sidewalk paving, rubber chips such as urethane rubber chips, EPDM rubber chips, and waste tire rubber chips are crushed into small pieces of 2 to 5 mm size. 18-25% by weight of urethane binder is added to 100% by weight of the crushed pieces, and the resulting mixture is added and laid during the on-site paving work of the sidewalk, and then the road surface of the paved sidewalk 10 is leveled.

  Before the paved sidewalk 10 is cured, a binder is applied to the bottom of the logo block 30 and the logo block is placed at a desired position on the sidewalk. Heat treatment is performed using a heating roll, and the logo block is fixed to the road or sidewalk while leveling the road surface of the paved sidewalk.

  As a result, the logo block 30 having the logo design is inserted into the paved sidewalk during paving work. This road surface leveling is performed so that the solid block (no logo design) block with the logo block has the same height.
