Abstract

PROBLEM TO BE SOLVED: To provide an execution work method of a road sign clearly visually confirmable over a long period by having high durability and causing no partial abrasion such as causing a slip of a tire. SOLUTION: A recessed part 2 is formed by cutting a road surface 1 along a place for drawing a sign of the road surface, and a road sign material 3 is supplied and fixed to the recessed part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a road marking for marking a pedestrian crossing or a traffic rule on a road.

[0002]

2. Description of the Related Art Conventionally, a road sign is constructed by directly applying a sign material to a road surface. The marking material is composed of a mixture of, for example, a thermoplastic binder, a plasticizer, a body material, glass beads, and the like, and the thickness on the road surface after coating is usually about 0.2 to 1.0 mm. is there.

[0003]

[Problem to be Solved] However, the sign constructed by this conventional construction method becomes higher than the road surface by about 0.2 mm to 1.0 mm, the friction of the vehicle tires becomes larger than the friction of the road surface itself, and the service life of the sign is reduced. It becomes short and the sign is easy to disappear. Further, the coating film may be easily peeled off from the road surface by applying a mechanical impact force from the tire of the vehicle.

[0004] In addition, the sign has a problem that the edge is easily worn, and the cross section of the worn portion is high at the center and rises in a curved shape, so that a tire or a pedestrian tends to slip.

The present invention has been made in view of the above-mentioned circumstances, and has high durability, and therefore can be clearly recognized for a long period of time, and can be biased to cause slippage of tires or pedestrians. It is an object of the present invention to provide a method of constructing a road sign that does not cause abrasion.

[0006]

SUMMARY OF THE INVENTION In response to this object, a method for constructing a road sign according to the present invention is characterized in that a concave portion is formed by cutting a portion of a road surface where a sign is to be drawn, and the concave portion has fluidity. It is characterized by supplying and solidifying road marking materials.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings showing an embodiment. In FIG. 1, reference numeral 1 denotes a road surface on which a road is to be marked, which is made of concrete or asphalt. When a road sign is to be constructed on the road surface 1, a figure or a character to be drawn, such as a striped pattern indicating a pedestrian crossing or a figure indicating traffic rules, is formed by shaving the road surface with a cutter to form a shallow groove 2. The depth is selected depending on the condition of the road surface and the type of the sign, but is usually 0.2 mm to 30 mm.
Or more. Use a mask or masking tape as needed when shaving the road. When the cutting of the shallow groove 2 is completed, dust generated by cutting in the shallow groove 2 is cleaned and removed by blowing air or suction.

After the formation of the shallow groove 2, the marking material 3 is applied or poured into the shallow groove 2 before the new surface of the road surface is soiled by cutting, and the surface 4 is made the same as the height of the road surface 1. Then, depending on the material of the marking material to be used, the material is air-dried or heated and solidified. When applying or pouring, a mask or a masking tape is used as necessary. As the marking material 3, a commercially available road marking material (for example, Ardline (manufactured by Atmix Co., Ltd.)) or Trahipe Paint (manufactured by Ishikawa Paint Co., Ltd.) can be used. The material of the marking material 3 needs to have almost the same durability and abrasion resistance as the road surface 1 in a solidified state.

The marking material 3 filled in the shallow groove 2 and solidified
Is constructed to be the same height as the road surface or slightly higher than the road surface, for example, 0 to 3 mm higher. The marking material 3 is densely filled so that no gap is formed between the marking material 3 and the side surface of the shallow groove 2, or after the filling, a pressure is applied from above to the shallow groove 2 by its own weight or an external force to bring it into close contact with the bottom surface or the side surface of the shallow groove 2.

[0010]

According to the road marking constructed in this manner, the surface 4 of the marking material 3 and the road surface 1 are flush or almost flush with each other. The surface 4 and the road surface 1 are the same or almost the same.
Only wear is eliminated, so that the service life of the sign is prolonged and the sign can be clearly seen over a long period of time. In this way, the life and service life of the road after the road rehabilitation are extended, and the economic effect is great. Also, since the surface of the marking material does not rise from the road surface 1 in a curved surface, the tire or the pedestrian does not slip by the marking material. Also,
The construction is easier than the case where the sign is formed by embedding blocks and tiles on the road surface.
