Abstract

<P>PROBLEM TO BE SOLVED: To provide a nonslip pavement construction method causing neither chipping nor end damage by a blade of a grader used in snow removal work and making no noise by tires at a boundary part between a section in which nonslip pavement is installed and a section in which nonslip pavement is not installed. <P>SOLUTION: The nonslip pavement construction method comprises a first step of forming one or more grooves 10 narrower in width than the blade width 20 of the grader for snow removal in the passing direction of vehicles, and a second step of filling a nonslip pavement material 12 in the grooves so that the upper face of the nonslip pavement material is almost flush with the road surface. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a slip prevention pavement construction method. More specifically, the present invention relates to a non-slip pavement construction method that is not easily worn or damaged during snow removal work in a snowy cold region.

In cold regions, anti-slip pavements are installed in front of intersections, sharp curves, steep slopes, etc., and resin-based anti-slip pavement materials are used as anti-slip pavement materials without using asphalt or modified asphalt. Has been. Resin-based non-slip paving materials are known, for example, in Patent Document 1, Patent Document 2, Patent Document 3, and the like.

As the construction method of the non-slip pavement, there are a method of applying a non-slip pavement material in a thin layer on a new or existing pavement surface, a method using a spray, and the like.
In addition, regarding a method for displaying various road surfaces such as a center line, a pedestrian crossing, a speed limit display, etc. provided on the road surface of a paved road, Patent Document 4 describes that it is easy even in a cold region using a grader or the like during snow removal work. As a method of forming a road surface display that does not easily disappear, a method of filling a display material into a groove having a predetermined width formed on the road surface is shown.

The anti-slip pavement is constructed by coating or spraying on the new or existing pavement surface by the thickness of the non-slip pavement material. There is a problem that it is scraped off and an end portion of the non-slip pavement material is damaged by the blade of the grader.

Furthermore, because the thickness of the anti-skid pavement material protrudes from the pavement surface, there is a step at the boundary between the section where the non-slip pavement is installed and the section where it is not installed, and noise due to tires is generated There are challenges.

This invention is for solving the said subject, Comprising: The 1st process of forming a groove | channel in a pavement road surface, and the 2nd process of filling a slip prevention pavement material in the said groove | channel are characterized by the above-mentioned. Is.

The first step is characterized in that single or plural grooves having a width smaller than the blade width of the snow removal grader are formed in the vehicle passage direction.

The second step is performed such that an upper surface of the anti-skid pavement material is substantially flush with the road surface.

The anti-skid pavement material includes a hard aggregate in a resin anti-slip pavement that melts at a high temperature, and the particle size of the hard aggregate is selected to be smaller than the depth of the groove. It is characterized by being.

According to the present invention, the anti-skid pavement material is filled in the groove having a width smaller than the blade width of the snow removal grader so that the upper surface of the anti-skid pavement material is substantially flush with the road surface. Even if the road surface is sometimes rubbed with a grader, it will not be scraped off or damaged, and a non-slip pavement that has a non-slip effect over a long period of time can be obtained. Further, the anti-slip pavement material includes a hard aggregate in a resin anti-slip pavement that melts at a high temperature, and the particle size of the hard aggregate is selected to be smaller than the depth of the groove. In addition, since the hard aggregate stays in the groove, the anti-slip effect can be maintained for a long time.

Further, since the upper surface of the non-slip pavement material is filled in the groove so as to be substantially flush with the road surface, a step is generated at the boundary between the section where the non-slip pavement is installed and the section where it is not installed. Therefore, there is an effect that no noise is generated by the tire.

Next, a slip prevention pavement construction method according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a series of diagrams showing the steps of a slip prevention pavement construction method according to a preferred embodiment of the present invention.

In the slip prevention pavement construction method of the present invention, first, a single or a plurality of grooves 10 having a width smaller than a blade width of a grader used for snow removal work in winter are provided on a road surface on which the slip prevention pavement is constructed. It forms in a direction (refer Fig.1 (a)).

Next, the anti-skid pavement material 12 is filled in the groove 10 (see FIG. 1B). The anti-slip pavement material 12 includes a resin anti-slip pavement material that melts at a high temperature and a hard aggregate, and any known one may be used. Since the hard aggregate has an anti-slip effect, the particle size of the hard aggregate is smaller than the depth of the groove 10 in order to remain in the groove 10 and reduce wear and damage by the blade of the grader during snow removal. Select as follows.

The groove 10 may be a single groove having a width slightly smaller than the blade width of a grader used for snow removal and snow work, or may be a plurality of grooves only as a tire portion of a passing vehicle. The width of the groove is made smaller than the blade width. (See FIGS. 1 (c) and (d))

The anti-slip material to be used is of a type that melts at high temperature and solidifies at room temperature. In use, the material that has been heated and melted is filled into the groove 10. When filling, the top surface of the non-slip pavement material is almost flush with the road surface.

It is a series of figures showing a process of a slip prevention pavement construction method according to a preferred embodiment of the present invention.
