Abstract

[PROBLEMS] To eradicate weeds generated in a gap between an asphalt pavement material and a concrete product after a long time on the road structure over a long period of time. Develop a structure for repairing gaps on roads that can be easily, reliably and quickly constructed to protect the road and prevent expansion.
SOLUTION: In the gap between concrete and asphalt, weeds that grow from the gap are removed, or rooted, and the soil, sand, and dust to be filled are removed, and then the gap is filled with mortar and the like. An adhesive layer X is formed across the gap, a urethane resin layer Y is formed on the adhesive layer, a coating material layer Z is formed on the urethane resin layer, and a coating material layer Z is formed on the coating material layer Z. An anti-slip means is formed if necessary.

Description

  The present invention relates to a repair structure for a gap in a road.

  In recent years, with the progress of road construction and changes in social conditions, road maintenance and repair work has become repetitive maintenance management on both general roads and highways, and an enormous budget is required every year.

  These maintenance and management operations require a large amount of expenses, and at the same time, traffic congestion due to road regulations is incurred in the management operations. In some cases, workers can develop unexpected accidents due to traveling vehicles. There was also a case.

However, in the original technology, it is necessary to consider the advantageous conditions for sprayed urethane as shown below, and to prevent road weeding and the expansion of cracks / destructions. There was a limit to the construction method. For example, as in Patent Document 1.
JP 2004-285571 A

  Therefore, the purpose of this device is to eradicate weeds generated in the gaps between asphalt pavement materials and concrete products, etc. that occur after a long period of time on the road structure, and is said to be the fate of the structure. The purpose is to develop a repair structure for gaps in roads that can be easily, reliably and quickly constructed to protect cracks and fractures and prevent expansion.

  The structure for repairing gaps in roads according to this device is for removing dirt, dust, etc. that are removed or cut down and filled in the gaps between roads, for example, concrete and asphalt. After removing the object, a filler such as mortar is provided in the gap, an adhesive layer is formed across the gap, a urethane resin layer is formed on the adhesive layer, and a coating material layer is formed on the urethane resin layer. The anti-slip means is formed as necessary on the coating material layer.

  According to this device, due to the nature of the urethane resin, it can be applied completely, can suppress the generation of weeds over a long period of time, does not require annual weeding work, road maintenance, traffic safety, It has excellent effects such as the improvement of landscape and environmental aspects.

  In addition, cracking / destruction of the structure is a very important problem related to the useful life of the structure itself. However, the construction of the present invention prevents the spread of cracking / destruction and has a very beneficial effect. .

  Furthermore, even roads with complex shapes can be constructed without seams, and because of the ultra-fast drying, traffic can be made in about 30 minutes after construction, and traffic regulation time can be shortened. Moreover, since it has a tough finish, it has excellent mechanical strength, abrasion resistance, chemical resistance, and the like. In addition, since it can maintain elasticity over a wide temperature range, it can follow changes in the road.

  Furthermore, because it can be colored, it not only matches the landscape with the user's attention, but also improves the safety because the surface is anti-slip. In addition, it has outstanding film properties, has good follow-up to the behavior of the base, has excellent air resistance, completely protects the frame from cracks and fractures of pavement and structures, and prevents expansion Is effective.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In a gap portion on a road, for example, a gap portion between concrete and asphalt, weeds that grow from the gap portion are removed, or rooted and filled. Remove dirt, sand, dust, etc., fill the gap with a filler (W) such as mortar, and provide an adhesive layer (X) on the top of the filler (W). X) is coated, sprayed or sprayed with urethane resin and laminated to form a urethane resin layer (Y). A coating material is applied, sprayed or sprayed onto the urethane resin layer (Y) to form a coating material layer (Z ) Is formed, and is composed of a repair structure for a gap portion on a road.

(A) is, for example, concrete curb on the road, and (B) is asphalt laid on the sidewalk.
(A) is the gap between the concrete curb and the asphalt laid on the sidewalk, (B) is the weeds that thrive from the gap, and (C) is the foreign matter clogged in the gap (A). (C), (D) is a curing tape on both sides across the gap (A), and an adhesive layer is placed on the upper part of the gap (A) between the curing tapes (D) and (D). (X) to be formed.
The gap (A) on the road, as shown in FIG. 2 as a whole, is the gap between the median strip (C) and the roadway (see FIG. 3), the gap between the curb and the sidewalk, and the walking / roadway boundary line. The gap between the sidewalk and the slope (see FIG. 4) and the slope between the slope (see FIG. 5) are mentioned, but the invention is not limited to these locations.

  Further, the contaminant (C) clogged in the gap (A) specifically refers to earth / sand / dust, withered plant leaves / flowers / species, or scraps of vehicle parts.

  Furthermore, the adhesive (X) is a paste material such as a primer, and the urethane resin (Y) is applied, sprayed or sprayed thereon to be laminated, and the thickness of the urethane resin (Y) is about 2 mm. The width is about 100 to 200 mm and is applied or sprayed using a dedicated spraying machine.

  Further, the coating material (Z) is called a top coat, and is provided with anti-slip means by providing uneven stripes and lines or uneven shapes on the coating material (Z). is there.
