Abstract

PROBLEM TO BE SOLVED: To prevent a slip accident and improve the durability of a road surface by burying moving members in a plate-like body made of an elastic material with their surfaces exposed as a surface layer member, and installing the surface layer member on the road surface. SOLUTION: Moving members 3 are buried in a plate-like body 2 made of an elastic material such as natural rubber, synthetic rubber, or a synthetic resin with their surfaces exposed to form a surface layer member 1. The surface layer members 1 are continuously installed in the road width direction at the position of a road surface such as an intersection or a curve. The moving members 3 are moved in the vertical and horizontal directions by the action of a mounted load when a vehicle or a pedestrian passes on them, and the ice formed on the surface layer member 1 is crushed. Even if the surfaces of the moving members 3 are wetted by the melted water or rain, no slip occurs, and the water is discharged to the side ditch of a road through joints 4. A slip accident can be prevented, and the durability of the road surface can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface material for a road surface, and more particularly to a surface material suitable for a road surface where snow and ice are often formed.

[0002]

2. Description of the Related Art In winter, the use of spiked tires for vehicles running on frozen roads has been prohibited, and snow tires and studless tires have been used instead.

[0003]

However, even with these snow tires and studless tires, slippage occurs when driving or braking on intersections, hills and curves when the road surface is completely frozen, and rear-end collisions and collisions may occur. Occur. Further, there is a problem that the road surface is roughened by the snow tires and the like, and repair work of the road surface is required after the thaw.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is characterized in that a movable member is buried in a plate-like body made of an elastic material with its surface exposed to form a surface member, and the surface member is installed on a road surface. And According to such a configuration, ice that has frozen on the surface material of the road surface breaks due to the weight of the surface material embedded in the elastic material moving due to the weight of the ice when the vehicle or a pedestrian passes. Can be eliminated.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory cross-sectional view, and FIG. 2 is a plan view, in which 1 is a surface member. The surface member 1 is constructed by embedding a movable member 3 in a plate-like body 2 made of an elastic material such as natural rubber, synthetic rubber, or synthetic resin and projecting the head of the movable member 3.

[0006] The arrangement of the movable members 3 may be in any arrangement, for example, as shown in the figure, or may be arranged irregularly. The material of the movable member 3 may be any material such as wood, stone, concrete, synthetic resin, rubber, asphalt, brick, and the like, and the shape is not limited to a square as shown in FIG. The shape may be any shape such as a rectangle, other polygons, a circle, an oval, and an irregular shape.

As shown in FIG. 3, the movable member 3 is made of a woven or non-woven fabric made of natural fibers, synthetic fibers or metal fibers, or a fibrous body made of net-shaped or plate-shaped steel. The durable material 11 also serving as a stress or the like may be buried and arranged in a layered manner, and the durable material 11 has an end surface exposed on the surface as shown in the drawing, and may be arranged in any state. There are parallel, orthogonal or oblique directions.

In order to suppress elastic deformation in the lower portion of the inside of the plate-like body 2, a constraining member 12 such as a fibrous body made of woven or non-woven fabric of natural fiber, synthetic fiber or metal fiber, or a net-like or plate-like steel material. May be embedded in one or more layers. Further, the movable member 3 may be configured such that the buried portion in the plate-shaped body 2 is swollen from the head, so that the movable member 3 does not easily come off the plate-shaped body 2.

Further, the movable member 3 may be buried in the plate-like body 2 only once or several in a desired shape so as to arrange the end of the road or the deformed portion. The joint 4 may be flat, but may be a joint which rises and is inclined along the movable member 3 as shown in FIG. Reference numeral 5 denotes a support material, which is made of concrete or asphalt concrete. The block 1 is composed of a surface member 1 in which a movable member 3 is embedded in a plate-like body 2 and a fixing member 6 such as an anchor. Although this bearing material 5 is not always necessary, it is a structure that is extremely effective in actual construction, and all sides around the plate-like body 2, both sides facing each other in the longitudinal direction or one side thereof, and A protection portion 7 is formed at the height of the road surface so as to protect both sides or one side thereof in the lateral direction. Note that the configuration of the protection portion 7 is not limited to these, and for example, the protection portion 7 may be formed on the remaining three sides without being formed on one side in the peripheral longitudinal direction, or may be formed to be inclined. Can be

Therefore, when the surface member 1 is installed on a road surface,
The protection portion 7 is arranged, for example, at a front end in a direction orthogonal to the traveling direction of the vehicle, or is arranged so as to be parallel to the traveling direction. Further, as shown in FIG. 4, a breakage preventive member 8 made of a steel material or a synthetic resin may be attached to the inner corner portion of the protective portion 7, and as shown in FIG. The reflector 9 may be attached so as to be integrated.

Reference numeral 10 denotes a water guide made of various fibers or the like, which prevents water from penetrating into the lower surface of the support member 5 into a gutter or a drainage basin and drains the water to prevent cracks and cracks due to freezing. Although not always necessary, it can be installed as required. By installing the road surface material in this way continuously at the intersections and curves of the road surface in the width direction of the road, ice that has frozen on the road surface material is
When a vehicle or a pedestrian passes, the movable member 3 moves in the vertical and horizontal directions due to the effect of the overload, whereby the movable member 3 is crushed and slip is prevented.

Also, the movable member 3 may be melted by water or rain.
Even if the surface gets wet, the slip does not occur, and the water is discharged to the side gutter of the road by the joint 4. In addition, this installation state may be arranged in a line in the width direction of the road, or may be arranged in a plurality of lines. In this case, the protection unit may be installed so as to be linear, but the protection unit is staggered. You may install so that it may be arranged in a shape.

As described above, when the road surface material is disposed on the road surface, the frozen ice is crushed as described above. In addition, the movable member 3 increases the braking force of the vehicle. . Further, since the support portion 5 is provided with the protection portion 7, the corner portion of the movable member 3 is not damaged or peeled off when the vehicle passes, and the inner corner portion of the protection portion 7 is not damaged. By attaching the member 8, it is possible to prevent the inside corner of the protection part 6 from being lost.

If the damage preventing member 8 is provided with a reflector 9, it can be used as a sign for a pedestrian crossing or a center line. In addition, since the water that has penetrated by the water-guiding member 10 is discharged to the gutter or the like, the lower surface of the support member 5 does not freeze, preventing cracks and cracks due to freezing and improving the durability of the road surface. .

[0015]

According to the present invention described in detail above, a movable member is buried in a plate-like body made of an elastic material with its surface exposed to form a surface member, and this surface member is installed on a road surface. The ice that has formed on the road surface is crushed when vehicles and pedestrians pass, and has an effect of eliminating a slip accident.

Further, there is also an effect that the road surface is durable and does not slip even when the movable member is wet.
