Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip paved road surface, and more particularly to a construction method for embedding a rubber anti-slip disk on a paved road surface.

[0002]

2. Description of the Related Art The use of spiked tires is prohibited due to environmental problems, and accidents frequently occur due to an increase in braking distance due to slip on a frozen road surface, which is becoming a problem.
Until now, a method has been proposed in which a large number of rubber or plastic slip stoppers are embedded on the paved road surface to prevent slipping.
(JP-A-57-58704, JP-B-3-4681, and JP-A-4-209204), the present invention is a further improvement of these.

[0003]

Since the construction of the non-slip construction is carried out on the road in use, a part of the traffic must be stopped, and the conventional construction method is time-consuming and requires a considerable time before the start of operation. Therefore, it is necessary to develop a rapid construction that shortens the time of road closure. Further, since the anti-slip rubber and the hole provided on the road surface do not fit perfectly and a gap is created, there is a drawback that the anti-slip rubber comes out in a short period of time by repeated passing of the automobile.

[0004]

[Means for Solving the Problems] Therefore, a rubber is fixed to a hole provided on a road surface by a quick-curing adhesive so that traffic service can be started immediately. By filling the caulking agent so that the hole sidewall and the non-slip rubber are held elastically,
It prevents the fixed rubber from easily slipping out of the hole under repeated traffic loads.

[0005]

[Function] By using a quick-curing adhesive, the time for interrupting traffic is shortened, and by filling the gap between the rubber and the side wall of the hole with a caulking agent, the rubber disc is elastically supported and repeatedly used. Make sure that the hole does not come out easily due to traffic load. Further, the rubber disc slightly laterally moves under the load of the passing vehicle to promote the peeling of the snow and ice coating formed on the road surface from the road surface.

[0006]

[Example] Diameter 50 mm, depth 30 mm on paved road surface 1
The holes 2 of No. 3 were staggered with a core drill to clean the inside. Prepared by mixing a fast-curing two-component epoxy resin adhesive (Three Longie F109, manufactured by ThreeBond Co., Ltd.),
An appropriate amount of an adhesive was applied to the bottom surface of the rubber disk 3 having a plurality of protrusions 4 on the upper surface, and embedded and fixed in the hole formed on the road surface. Furthermore, a caulking agent (manufactured by ThreeBond Co., Ltd., silicone sealant 5211) is provided in the gap between the rubber disk 3 and the hole 2.
E) Filled with a gun.

Instead of drilling holes on the existing road surface, a plurality of blocks having holes are previously spread and fixed on the road surface, and a rubber disk having a plurality of protrusions on the upper surface is also glued in the holes. There is also a method of fixing with, and filling the gap with a caulking agent.

The material of the rubber disk 3 is selected so that the elastic capacity is not deteriorated even at a low temperature and the abrasion resistance is excellent. The rubber used for studless tires is preferred. Furthermore,
It can also be used as a road sign by changing the color and shape of rubber. If the surface is mixed with glass beads, for example, if it is used for a pedestrian crossing, it will call the attention of the driver. Further, if the rubber disc is made conductive so as to have an appropriate electric resistance value, it is possible to prevent the road surface from freezing due to heat generated by energization.

75 mm in diameter and 20 m in depth on the paved road surface
m and holes having a diameter of 20 mm and a depth of 20 mm were deformed in a staggered shape, a lattice shape, an oblique lattice shape and the size and arrangement of the disks, but similar effects were obtained. From this, the size of the disk,
The diameter and depth of the hole can be changed as appropriate in consideration of installation conditions, cost, and the like.

[0010]

[Effect] The rubber disc prevents slippage of vehicles and pedestrians, and the caulking agent injected into the gap between the rubber disc and the hole elastically holds and fixes the rubber disc in the hole, and It also prevents the snow and ice from coming off easily and promotes the separation of snow and ice on the road surface.

Further, the rubber disc is distorted by the load of the passing vehicle, the peeling of the snow and ice film formed on the road surface from the road surface is promoted, and the vehicle is prevented from slipping due to slip during braking and pedestrian slip. You can
