[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a pavement surface, and more particularly to a construction method capable of forming a pavement surface excellent in appearance and water permeability.

[0002]

2. Description of the Related Art In recent years, with rapid urbanization, the environment surrounding houses and offices has changed significantly.
For example, due to the pursuit of functionality and rationality, much of the ground surface has become paved with concrete and asphalt, and the environment itself has become a dead landscape and is becoming less rich in life. In addition, covering the ground surface with concrete or asphalt makes it difficult to walk because puddle forms on the paved surface after rain because the concrete and asphalt have no water permeability.
Moreover, rainwater may not penetrate into the lower side of the pavement, causing a shortage of groundwater and eventually causing subsidence. In order to improve such inconvenience, recently, a construction method for forming a beautiful and water-permeable pavement surface by using a pavement material composed of an epoxy resin and a large number of natural stones has been provided. This construction method first mixes a two-part epoxy resin, puts the epoxy resin and a large number of natural stones of about 2 to 10 mm in a mixer, and stirs until the epoxy resin adheres to all the surfaces of the natural stone to form a paving material. By coating this pavement material on the base using a trowel or the like to form a pavement material layer, and curing the epoxy resin in the pavement material layer, as shown in FIG. Epoxy resin film 11 covering the surface of 10, that is, along the shape of stone 10.
The pavement surface is formed in the state of having. And
According to this construction method, the appearance and texture of the natural stone can be utilized as it is by using the transparent epoxy resin, and the epoxy resin is not filled between the natural stones. Since the epoxy resin is covered with a resin and the epoxy resin is fixed to each other to form the pavement material layer as a whole, a water-permeable channel can be formed between the natural stones to impart good water permeability to the entire pavement material layer. Therefore, the paving surface (paving material layer) obtained by the above method is widely used, for example, for promenades, building approaches, poolsides, general sidewalks, etc. due to the natural stone appearance and good water permeability. Of.

[0003]

By the way, the pavement surface formed by the above-mentioned construction method has a good slip resistance in a dry state and a sufficient slip resistance in a wet state, for example, in a public building. In areas where there are many people, such as entrances and exits, and where there are many people who wear slippery footwear such as leather shoes, it is desirable to have higher slip resistance in order to prevent accidental falls. There is.

The present invention has been made in view of the above circumstances, and an object thereof is to construct a pavement surface which is excellent in aesthetics, water permeability and the like and has a high slip resistance value even when wet. To provide a method.

[0005]

A method of constructing a paving surface according to the present invention is to mix an epoxy resin before curing and a large number of stones into a paving material, and apply the paving material onto a base to form a paving material layer. And laying on the paving material layer a smooth sheet having flexibility before the epoxy resin in the paving material layer is cured, and then pressing the sheet against the upper surface of the paving material layer, After the epoxy resin of is hardened, the sheet is removed from the top surface of the paving material layer to remove the top of the stone exposed on the top surface side.
The epoxy resin is formed smoothly and the stones
A groove is formed between the pavement material layer and the periphery of the pavement material layer.
And this <br/> forming a plurality of projections having a corner portion and has been smooth surface was solution of the above problems.

The construction method of the pavement surface of the present invention will be described in detail below. First, a base is formed. The base is formed, for example, by flattening the soil at the place where the pavement is to be made, and then hitting and solidifying the soil. Also, existing concrete or asphalt may be used as the base. Separately from this, a two-component epoxy resin is mixed and stirred until uniform. Here, the epoxy resin is not particularly limited, but it is preferable that the epoxy resin cures even when the temperature is low and has sufficient durability after curing, for example, System 5100 of Nippon Flowlock Co., Ltd. is suitable. It is said that

Next, the epoxy resin and a large number of stones are uniformly mixed, and the epoxy resin is attached to the entire surface of the stone to form a paving material. For stones, for example, those with a diameter in the range of 1 mm to 3 mm and those with a diameter in the range of 6 mm to 13 mm are 1 mm.
Those having a size of about 13 mm can be used, and natural stones as they are quarried from the river bottom, riverside, seaside, etc., crushed natural stones, and colored ones are preferably used. The stones quarried from the riverbed or riverside have a rounded shape, and most of the crushed stones have pointed portions, and are therefore appropriately selected and used according to the appearance and properties required at the construction site. Also, there are various stone colors,
For example, when white stones are used, the surroundings of the pavement surface are brightened after construction, and when brown stones are used, the atmosphere becomes calm. The method of mixing stone and epoxy resin is not particularly limited, and for example, a method of mixing with a mixer having a stirring blade or the like is adopted. Also,
Although the compounding ratio of stone and epoxy resin varies depending on the size and type of stone, it is preferable to use about 4 to 7 parts by weight of epoxy resin per 100 parts by weight of stone.

Next, the paving material thus obtained is transferred from a mixer or the like onto a base, and a trowel such as a plaster for a plasterer is used so that the base has a constant thickness of about 1 cm when the base is concrete. Used to form a flat pavement layer. At this time, it is preferable to apply lubricating oil to the iron in order to prevent the epoxy resin from adhering. Immediately after forming the paving material layer,
Lay the sheet on top of the pavement layer. For this sheet,
A flexible resin made of a vinyl resin that does not adhere to an epoxy resin such as vinyl chloride, polypropylene, or polyethylene is preferable.

Next, the sheet is pressed against the upper surface of the pavement material layer. The pressing method is not particularly limited, and as shown in FIG. 1, for example, a trowel 5 is pressed against the upper surface of the sheet 4 laid on the paving material layer 3 composed of natural stone 1 ... And epoxy resin 2. However, the position of the trowel 5 may be sequentially shifted, or may be pressed by using a roller. After a certain period of time, that is, after the epoxy resin 2 in the pavement material layer 3 is cured, the sheet 4 is peeled off from the pavement surface and removed.
A pavement surface as shown in FIG. 2 is formed.

According to such a construction method, the paving material layer 3
When the sheet 4 is pressed against, the epoxy resin 2 attached to the upper side of the stone 1 ...
As shown in FIG. 3, the stone 1 is hardened by its own weight and does not drip into the gap between the stones 1 and 1 along the surface of the stone 1 and adheres to the sheet 4. Here, the epoxy resin 2a that adheres to the sheet 4 and remains on the surface of the stone 1 is pressed by the iron 5 or the like even though the upper surface of the stone 1 has a curved shape, and as a result, the central portion of the upper surface (most sheet Part of the resin on the 4th side) remains on the stone 1 in a state of being extruded to the outer peripheral side. As a result, a step is formed between the epoxy resin 2a and the gap side A between the stones 1 and 1, and as a result, a protrusion B protruding from the surface of the stone 1 is formed on the outer peripheral portion of the epoxy resin 2a. It will be. By forming such protrusions B on the upper surfaces of the stones 1 ... Which are located at the top, the pavement surface obtained by the present invention has a high slip resistance. Further, in such a paving surface construction method, by covering the paving material layer 3 with the sheet 4 immediately after forming the paving material layer 3, a paving surface free from dust can be obtained.

In the above embodiment, the pavement material layer was formed to have a constant thickness and then the sheet was laid. However, a predetermined amount of the pavement material was placed on the base, the sheet was laid, and the sheet was placed on the sheet. The pavement material layer may be formed to have a constant thickness by pressing.

[0012]

According to the method of constructing a pavement surface of the present invention, a smooth and flexible sheet is laid on the pavement material layer before the epoxy resin in the pavement material layer is cured, and the sheet is then spread. By pressing on the upper surface of the pavement material layer, the epoxy resin on the upper side of the stone that is located at the top of the pavement material layer and exposed on the upper surface side ,
It hardens when attached to the sheet, which smoothes the top of the stone and creates grooves between the stones.
A smooth surface with corners on the top side of the pavement material layer.
A plurality of protrusions having are formed.

[0013]

EXAMPLES The present invention will be described in more detail below with reference to examples. (Examples 1 to 10) The main component of the epoxy resin and the curing agent were mixed and stirred until uniform. The epoxy resin thus obtained and 8 kinds of riverbed or riverside stones and 2 kinds of crushed stones shown in Table 1 were put into a mixer having a stirring blade, respectively, until the epoxy resin adhered to the entire surface of the natural stones. After stirring, 10 types of paving materials were obtained. The paving material was transferred from the mixer onto the base, and a flat paving material layer was formed using a plaster for iron so as to have a thickness of about 1 cm.
Immediately after forming the pavement material layer, a sheet made of vinyl chloride was laid on the upper surface of the pavement material layer. Then, the iron was applied to the upper surface of the sheet, and the sheet was pressed against the upper surface of the pavement material layer. Then, the position of the iron was sequentially shifted and the entire upper surface of the pavement material layer was pressed. After 72 hours, the sheet was peeled off and removed.

For each pavement surface formed by such a construction method, the slip resistance value when wet is A
According to the standard of STM E 303, the measurement was performed 5 times by a portable slip tester, and the average of those measurement values is shown in Table 1.

(Comparative Examples 1 to 10) Conventional normal construction using the same paving material as in Examples 1 to 10, that is, Examples 1 to 1
No. 0, the pavement surface formed by the construction method without using the sheet was measured for the slip resistance value when wet in the same manner as in the example.

[0016]

[Table 1]

From Table 1, it became clear that in all the examples, the pavement surface was larger than the standard value of the slip resistance of 40 BPN in consideration of sufficient safety, and it was a slip resistant surface.
