13 to 15 show a seventh embodiment of the present invention, in which the same parts as in the second embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted and will be described in detail. The configuration of the road according to this embodiment will be explained based on FIGS. 13 to 15. In the road according to the second embodiment, the sidewalk 21 is provided with a tree planting area 80. In the planting box 80, street trees 83 are planted in the soil 82 surrounded by the sidewalk boundary block 22 and the planting box boundary block 81 described in the second embodiment.

In addition, the surface of the soil 82 is a water-permeable member on which soil pavement (soil-based pavement) is constructed, in which the surface of the soil 82 is paved with a paving material made of a mixture of natural materials such as soil or sand and a solidifying agent mixture. A certain soil paving layer 84 is formed.

By forming the soil paving layer 84 on the surface of the soil 82, the soil 82 not only has weed prevention properties, but also has a landscape that harmonizes with the natural environment, high water permeability, high water retention, moderate elasticity, and moderate impact. This results in superior effects such as absorbency.

As shown in FIG. 13, the procedure of the weed control method for roads in which the above-mentioned sidewalk 21 is provided with a planting box 80 will be explained. Note that descriptions of parts that overlap with Example 2 will be omitted.

Here, if the boundary block 22, the boundary block 81 for the planting box, and the soil paving layer 84 are damaged, the boundary block 22, the boundary block 81 for the planting box, and the soil paving layer 84 are damaged at this stage. Repair or replacement is preferred. Subsequently, the earth and sand in the gaps 85, 86, and 87 are replaced with a filler such as mortar.

Next, move on to the weed control process. First, a part 21AA of the road surface 21A of the sidewalk 21, a gap 87 between the road surface 21A and the boundary block 81 for the planting box, the entire upper surface 81A of the boundary block 81 for the planting box, and the entire top surface 81A of the boundary block 81 for the planting box. A gap 86 between the boundary block 81 and the soil pavement layer 84, a continuous range up to a part of the soil pavement layer 84, and a construction range continuous with the covering layer 28 described in Example 2, the boundary block 22 and the soil pavement layer. An adhesive layer 88 is formed by applying, spraying, or spraying an adhesive made of a glue material such as a primer to the gap 85 of 84 and a continuous range up to a part of the soil paving layer 84.

Subsequently, a urethane resin is applied, sprayed, or sprayed onto the adhesive layer 88 to form a urethane resin layer 89. Here, the urethane resin used for the urethane resin layer 89 is the same as that in Example 1.

Furthermore, a coating material layer 90 is formed by applying, spraying, or spraying a coating material onto the urethane resin layer 89 .

In this embodiment, a coating layer 91 formed by laminating an adhesive layer 88, a urethane resin layer 89, and a coating material layer 90 in this order covers a portion 21AA of the road surface 21A of the sidewalk 21, and a boundary between the road surface 21A and the planting box. A gap 87 between the block 81, the entire upper surface 81A of the boundary block 81 for the planting box, a gap 86 between the boundary block 81 for the planting box and the soil paving layer 84, and a part 84A of the soil paving layer 84. and a continuous range from the gap 85 between the boundary block 22 and the soil paving layer 84 to a part 84B of the soil paving layer 84 as a construction range continuous to the covering layer 28 described in Example 2. The construction area will be constructed continuously.

Here, the range 91A of the covering layer 91 that covers the part 21AA of the road surface 21A, and the ranges 91B and 91C that covers the parts 84A and 84B of the soil paving layer 84 cover the respective gaps 85, 86, and 87. The area is such that it covers several centimeters to several tens of centimeters of the road surface 21A or the soil pavement layer 84 continuously from that part.

As described above, the road weed control method of this embodiment includes the steps of forming the adhesive layer 88, laminating the urethane resin layer 89 on the adhesive layer 88, and layering the coating material on the urethane resin layer 89. 90, and covers a construction range with a covering layer 91, the construction range includes a part 21AA of the road surface 21A and a boundary block 81 between the road surface 21A and the boundary block 81. A gap 87, the entire upper surface 81A of the boundary block 81, a gap 86 between the boundary block 81 and the planting area 80, which is a planting area divided by the boundary block 81, and a part of the planting area 80. 84A, it is possible to provide a weed control method with excellent scenery by forming a continuous covering layer from the road to the planting area.

Furthermore, by covering the planting box 80 with the soil paving layer 84 which is a water-permeable member, it is possible to provide a weed control method that does not hinder the growth of the street trees 83 in the planting box 80 and is excellent in scenery. .
