The present invention relates to a paving method and a paving material.

[0002]

2. Description of the Related Art Conventionally, paving with cement or asphalt has been generally used in the construction of sidewalks, but recently, comfort and calm living environment are required, and even on roads. There is a growing demand for environmental designs that incorporate colors rather than exposed concrete or asphalt.

[0003] In response to such demands, color coating is applied to the pavement surface or pavement material is pigmented to be used for pavement, but it has the drawback of fading easily and color matching during repair. There was a problem that it was difficult.

There is also a method of laying colored bricks or blocks, but there is a problem that uneven subsidence occurs after laying, and a reference line is set when arranging these or it corresponds to a place to be laid. However, there is a drawback in that the work such as cutting the ends of the bricks and blocks requires time and effort.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its purpose is to make the construction simple and to prevent discoloration and uneven settlement after construction. The object of the present invention is to provide a paving method and paving material which can be easily repaired, can be given various colors and patterns, and have excellent water permeability and corrosion resistance.

[0006]

[Means for Solving the Problems] That is, as a means for solving the above-mentioned problems, the invention according to claim 1 states that "colored glass having a particle size of 2 to 10 mm at a weight ratio of 20 to 70% is colored glass. And gravel of the same particle size are kneaded, epoxy resin is added as a binder at a weight ratio of 6 to 12%, and silica sand is further added to create a pavement material, which is dried well. The pavement method is characterized by laying it evenly on a base material, finishing the surface with a trowel, and curing it. "

Further, the invention according to claim 2 is that "aggregate contains colored glass having a particle size of 2 to 10 mm and a weight ratio of 20 to 70%, silica sand having a weight ratio of 5 to 10%, and a weight ratio of 6 to 12". % Pavement material that is mixed and bonded with an epoxy resin ”
The contents are.

The colored glass used in the paving method and the paving material of the present invention is not limited to the colored glass which is wholly colored, but includes those whose surface is colored by screen printing or the like.
The type of coloring does not matter. The colored glass includes transparent glass. Commercially available colored glass may be used, or industrial waste glass such as glass bottles discharged from each household may be used. Industrial waste glass, which requires a large amount of expense for disposal as an incombustible material, can be effectively used.

According to the present invention, the shape of the pavement base can be freely adjusted, and the pavement surface has a water-permeable structure.
Further, since the epoxy resin serving as the binder has good adhesiveness and does not peel off even with thin layer pavement, the particle size of the colored glass used as the aggregate is preferably 2 to 10 mm. Further, it is preferable to use the colored glass mixed with gravel in a weight ratio of 20 to 70%. The reason for this is that glass generally has weak impact resistance and is problematic in terms of strength. This is because the surface can be formed.

Gravel can be mixed homogeneously with colored glass by using gravel having a particle size similar to that of colored glass. Further, by using gravel having a particle size similar to that of colored glass, it is possible to freely conform to the shape of the pavement base and form a pavement surface having a water-permeable structure. The gravel may be river gravel, mountain gravel, sea gravel, or the like, but it is preferable that impurities such as viscous lumps are removed by washing with water in order to enhance the adhesiveness with the binder.

The epoxy resin as the binder has good adhesion to the base cement, asphalt, steel floor plate and gravel as aggregate and glass, and has excellent heat stability, as well as abrasion resistance, oil resistance and water resistance. It has the advantage of excellent property. The epoxy resin used in the pavement method and pavement material of the present invention is preferably prepared by mixing a main agent and a curing agent (amine-based) and curing the resin, since a required amount of the epoxy resin is prepared according to the construction conditions at the site. Since the curing time can be changed depending on the mixing ratio of the main agent and the curing agent, the construction can be performed according to the weather and temperature at the time of construction. Further, it is possible to prepare an epoxy resin having an appropriate flexibility by the blending ratio of the main agent and the curing agent, and it is possible to well follow an underlayer such as a steel floor plate that expands and contracts due to changes in temperature. .

The epoxy resin is mixed in a weight ratio of 6-12.
% Is preferred. If it is less than 6%, the joint between the aggregates is not sufficient and the strength is weakened, and if it exceeds 12%, the gap between the aggregates is filled, and as a result, it becomes difficult to impart water permeability. For this reason, it is preferable to mix the epoxy resin in a state in which it adheres to the surface of the aggregate to the extent that dripping does not occur.

Silica sand has the function of forming the surface of a hardened epoxy resin in the shape of a shark skin and stopping the slipping of the epoxy resin. The silica content is preferably 5 to 10% by weight.

[0014]

In the paving method according to the present invention, the particle size is 2 to 10 m.
m, 20 to 70% by weight of colored glass and gravel having the same particle size as the colored glass are kneaded, and an epoxy resin as a binder is added thereto at a ratio of 6 to 12% by weight, and further silica sand is added. Since the paving material mixed and mixed is spread on the base, the construction area and construction thickness can be freely selected, and it can be applied to various foundations. It is possible to form a paved surface having various colors and patterns by making the color of glass stand out as it is, and to form a paved surface having excellent water permeability and corrosion resistance. In addition, since the pavement surface is formed of a bonded body that is evenly bonded, unlike the pavement surface formed by spreading the blocks, uneven settlement does not occur.

In the paving material according to the present invention, the epoxy resin serves as a bonding agent for the colored glass and the gravel, and at the same time, wraps the sharp glass to ensure the safety. In addition, silica sand works to prevent the epoxy resin from slipping. Therefore, by changing the type of colored glass or the type of gravel, it is possible to easily form a pavement surface with various colors and patterns, and to fade even after a long period of time. There is no.

[0016]

EXAMPLES An example of the paving method of the present invention will be described below.
FIG. 1 is a flow chart showing an example of the paving method of the present invention. As shown in the figure, the dry aggregate has a grain size of 2-10.
mm colored glass and gravel are prepared, and the mixture is kneaded in a mixer at a predetermined mixing ratio. It is preferable that the aggregate is well dried in order to adhere well to the epoxy resin serving as the binder and to prevent the epoxy resin from being whitened during curing due to water. When industrial waste glass is used as the colored glass, it is advisable to separate it in advance and prepare it by crushing it for each color.

By mixing the colored glass as the aggregate and the gravel by kneading with a mixer, an epoxy resin mixed with a main agent and a curing agent as a binder is added, and silica sand is added as a filler at the same time. , Mix everything well (mixer mix).

On the other hand, the base is cleaned in advance to remove dust and the like and dried (base cleaning). This is to improve the adhesion of the paving material. Next, the part on which the paving material is spread is surrounded by a formwork (formwork work). Tack coat is a process to make it easier to bond the paving material to the base before spreading the paving material. It is a process to apply a liquid obtained by diluting the epoxy resin as a binder with a solvent such as acetone to the base surface. . This tack coating may be performed depending on the condition of the base.

Now, when the groundwork is prepared, the paving material mixed with the mixer is spread on the portion surrounded by the formwork on the groundwork (paving material spreading). Then, the surface of the paving material laid evenly is pressed down with a trowel to finish (trowel finishing). In the case of thin layer paving, finishing with a roller or the like is not preferable because the paving material adheres to the roller surface. After finishing with the trowel, it is cured to cure the epoxy resin.

As shown in the schematic view of FIG. 2, the paved surface formed by such a paving method is such that the colored glass 1 and the gravel 2 are bonded to each other by the epoxy resin 3 which is a binder, and the paving surface is finer. A large amount of silica sand 4 adheres,
A gap 5 which is not filled with the epoxy resin 3 is formed between the colored glass 1 and the gravel 2 so that the structure allows water to pass therethrough.

[0021]

As described above, the paving method according to the present invention has the following effects. 1. There is no fear of discoloration or uneven settlement after construction, and repairs can be done easily, making it possible to easily form paving surfaces with various colors and patterns, and to provide paving surfaces with excellent water permeability and corrosion resistance. Can be formed. 2. You can freely select the construction area and construction thickness, can be applied to various foundations, and unlike the conventional method of laying bricks and blocks, it is troublesome to cut the ends of bricks and blocks according to the place to be laid. No work is required and construction is easy.

Further, the pavement material according to the present invention is capable of color pavement without using a pigment, and unlike pavement using a pigment, there is no effect of fading or fading even after a long period of time. Have.
