Abstract

PROBLEM TO BE SOLVED: To improve work execution properties by installing a template along a road carriageway marking of the mixture for pavement, and detaching the template from a road surface after the rolling compaction. SOLUTION: After the mixture for pavement such as ASCON of small grain size is laid, a template is installed along a carriageway marking provided on right and left sides of a paved road surface. The road surface is roll-compacted by a tamping machine such as an asphalt finisher to press the template into the paved surface, the template is detached from the road surface to form a groove in the road surface. The template is formed of a flat member having the pattern of the wire member such as wire corresponding to the groove, and the whole or at least a part of the template is flexible, and the template is formed by connecting a part in the longitudinal section along the vehicle advancing direction to a part orthogonal thereto at one or two parts. Continuous grooves to draw a driver's attention can be easily and surely formed, and the template is recyclable so as to be subjected to low-cost work execution.

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 pavement surface provided with an alert function for alerting a driver who has deviated from a lane marking due to aside or falling asleep.

[0002]

2. Description of the Related Art As a pavement having a function of alerting a driver who has deviated from a lane marking, an uneven lane mark or a combination of a lane mark and a road stud are known in Japan. In Japan, there is a method of giving such a caution function, such as a concavo-convex lane mark or a combination of a lane mark and a road stud, which alerts a driver who runs off a lane marking. Overseas, a method is known in which a groove is formed laterally from an outside line of a road by rolling pressure of a reinforcing-bar mounting roller when asphalt mixture is laid.

[0003]

However, at the present time, the former is expensive and has a problem as an impurity when it is used, for example, as a recycled mixture for asphalt pavement. In addition, the latter method using a rebar mounting roller is inexpensive, but the type of asphalt mixture is limited in order to properly form the required grooves, or the grooves are displaced at the time of construction, and it is the most used method in Japan. However, there is a problem in that the required grooves cannot be formed properly in the high-density ascon. The present invention solves such a problem of the prior art, and can easily and reliably form a continuous groove having an appropriate function of alerting a driver along a lane marking on a pavement surface, and It is intended to provide a method for constructing an inexpensive and recyclable road surface.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a template member is placed along a road lane line of the pavement after paving the paving mixture, and the template member is released from the pavement surface by rolling with a rolling machine. And forming a plurality of grooves continuously on the pavement road surface.

The template member used in the present invention is a flat member having a pattern of a linear member such as a wire corresponding to a groove to be provided. A template member having a characteristic of being bent to the original shape and being restored to the original shape) is preferably used. Also, when the vehicle is installed along the lane marking, if the traveling direction of the vehicle is the longitudinal direction and the lateral direction is the transverse direction with respect to the traveling direction of the vehicle, the longitudinal direction and the transverse direction are joined at one place. Two or more template members are particularly preferably used. FIG. 1 shows a shape model of such a template. By reducing the connection of the template parts, not only a straight line but also a road or a lane mark can be set along a curved line. In addition, when the portion in the longitudinal direction and the portion in the transverse direction of the template are viewed from one direction, the distance and the angle are not limited.

In the present invention, the above-mentioned template member is
After laying the asphalt pavement mixture, etc., it is installed along the road division line (planned position), press-fitted with a compaction machine such as an iron roller, and then the template member is released.
By continuing the same operation along the road division line, the alert pavement is constructed. FIG. 2 shows an example of a place where the alert function is provided. Of course, the six embodiments in FIG. 2 are merely examples. Although the method of the present invention is suitable for asphalt pavement, it can also be used for RCCP or resin concrete for rolling.

[0007]

[Example] Dense-grain ascon (13 mm top) with an area of 1
20 m ² (width 6 m, extension 20 m, thickness 4 cm), spread with an asphalt finisher. In addition, an iron wheel roller and an iron wheel roller with a reinforcing bar were prepared as rolling machines. Immediately after the fine-grained ascon (13 mmtop) was spread, it was divided into the right side and the left side of the pavement surface in the traveling direction of the asphalt finisher, and at the same time, compaction was performed as shown in FIG. In the press-fitting method on the left side, five template models of the template shown in FIG. 1 were installed on the left side in the traveling direction of the asphalt finisher as shown in FIG. Next, after making two reciprocations with an iron wheel roller, the template was separated from the road surface. Thereafter, the five detached templates are again placed on the left side in the traveling direction of the asphalt finisher as shown in FIG.
After making two reciprocations with an iron wheel roller, the template was separated from the road surface. FIG. 4 shows the grooves formed at this time from the cross-sectional direction of the pavement. For comparison, the right side was rolled back and forth two times using a steel wheel roller with a reinforcing bar (the roller partial cross-sectional view is shown in FIG. 5) on the right side in the traveling direction of the asphalt finisher. FIG. 4 shows the grooves formed at this time from the cross-sectional direction of the pavement. As shown in FIG. 4 and FIG. 4, the groove on the road surface using the template was finished more clearly than the groove on the road surface using the iron wheel roller with a reinforcing bar.
