Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a road paved with asphalt or concrete, especially on a road surface such as a highway.
The present invention relates to a road surface drainage method for draining rain and snowmelt water so that they do not collect.

[0002]

BACKGROUND OF THE INVENTION Road pools are very dangerous to the driver of a car. Water collects in recesses and valleys on the road surface. It can be topographical or a rut on the tire.

The conventional road surface drainage method includes a method of excavating a drainage groove that crosses the road surface, and a method of laying a drain (trough) made of vinyl chloride having a water collecting hole on the upper surface in the drainage groove.

[0004]

The conventional road surface drainage method has the following problems.

When excavating a drainage ditch across a road surface, a passing vehicle and a driver feel a great impact. Due to this impact, the drainage ditch has a very short life. The impact sound is a noise that sounds not only to the driver but also far away.

The edge of the drain is gradually shaved and damaged. Since the groove widens, the impact when passing is increased, and because the groove becomes shallow, the tire scratches out the water in the rain and raises the splash.

After a certain amount of time, the groove is completely filled with scraped asphalt, concrete, sand, dust, etc., the function of the drainage groove is completely lost, and water is accumulated in the concave portion and the valley portion of the road surface.

When a drain made of vinyl chloride is laid in the drainage trench, excavation is performed so that the upper surface of the drain is located at a position lower than the road surface even in a shallow portion (a bottom of a recess or a valley portion) of the groove crossing the road surface. The reason is that the tire is slippery on the upper surface of the drain, and when the rut grows and becomes deeper, the drain projects and collides with the tire. Therefore, the construction method using the drain has the same problem as the above-mentioned mere drainage ditch. In other words, the impact and noise during passage, the spread of grooves, the scraped asphalt, concrete, sand, dust, etc., clogging the inside of the drain and the water collection holes, drainage function is lost, and For example, water collects. Since the material is not flexible, it cannot be used where the groove 2 is bent. Since the drain is assembled on site, work efficiency is poor and it takes time to construct.

The mere drainage grooves and drains give the impression that the road surface is fragmented. In addition, the spectacle of debris and the like deteriorating the aesthetics of the road.

An object of the present invention is to provide a road surface drainage method capable of solving the above problems.

SUMMARY OF THE INVENTION The present invention is a U-shaped cross section having a side surface cut perpendicularly to a road surface paved with asphalt or concrete so as to communicate with a drainage facility such as a gutter across a road and an excavated bottom surface. -Shaped groove is formed, a rubber chip binder elastic material having water permeability is fitted and adhered to the groove, and the upper surface of the rubber chip binder elastic material is formed so as to present an integrated surface with the road surface. It is related to the construction method.

[0012]

In the rubber chip binder elastic material 3 described above, since the rubber chip is strongly covered and adhered with a thick binder film, water permeability, elasticity, strength, shock absorption,
Excellent durability and workability. It does not expand due to water, does not depend on temperature, does not clog, has excellent weather resistance and ozone resistance, maintains a constant state at all times, and is easy to maintain. With rubber elasticity and a moderate gap, no impact or noise is generated when passing a car, it fits well on the tire and it is hard to slip,
You can get a comfortable and safe driving feeling. Since the edge of the groove 2 is reinforced by the rubber chip binder elastic material 3, asphalt or concrete is not scraped or damaged.
Even if the groove 2 traversing the road is bent, the rubber chip binder elastic material 3 can conform to the shape of the groove 2.
The rubber chip binder elastic material 3 is less expensive than the method using a drain made of vinyl chloride.

Water on the road surface 1 permeates from the upper surface of the rubber chip binder elastic material 3 into the rubber chip binder elastic material 3 and is drained to the outside of the road along the groove 2. There is no place for sand or dust to collect.

Although not shown, the height of the rubber chip binder elastic material 3 before fitting and adhering to the groove 2 is higher than the deepest portion of the groove 2 which crosses the road. After fitting and adhering to the groove 2, the upper surface of the rubber chip binder elastic material 3 is cut according to the shape of the road surface 1. Road surface 1 and rubber chip binder elastic material 3
By forming the upper surface of the road so as to present an integral surface, the appearance of the road surface 1 becomes beautiful. The existence of the groove 2 for draining the road surface that crosses the road is due to the rubber chip binder elastic material 3
It becomes inconspicuous due to the mating, and there is no danger of attracting the driver's unnecessary attention.

The rubber chip binder elastic material 3 has good workability and quick adhesion. Work efficiency is good and construction can be completed in a short time.

After construction, even if the ruts grow and the valleys become deep and the rubber chip binder elastic material 3 projects from the road surface 1, no impact or noise is generated when the tire passes through.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings, but it goes without saying that the present invention is not limited to this embodiment.

FIG. 1A shows a perspective sectional view of a road, and FIG. 1B shows a front sectional view. 4 in the figure is a rut.

In the figure, reference numeral 1 indicates a road surface paved with asphalt or concrete.

Reference numeral 2 in the drawing denotes a groove excavated so as to cross the road surface 1. Although not shown, the groove 2 communicates with a drainage facility such as a gutter. The side surface of the groove 2 is cut by a cutter and is vertical, and the bottom surface is notched because it is excavated.

Reference numeral 3 in the drawing denotes a rubber chip binder elastic material which is fitted and adhered to the groove 2 and whose upper surface forms a surface integral with the road surface 1. Although not shown, the length is longer than the depth of the groove 2 before fitting adhesion and surface formation. The width is slightly shorter than the groove 2 and has an elongated columnar shape. In some cases, an elastic material of rubber chip binder is used for compounding and construction at the site.

In the figure, reference numeral 5 denotes a putty-like super early strong adhesive material, which firmly adheres the side surface and the bottom surface of the rubber chip binder elastic material 3 to the side surface and the bottom surface of the groove 2. The bonding portion 6 of the rubber chip binder elastic material 3 is also bonded with the ultra-early strong adhesive material 5.

[Effects of the Invention] According to the road surface drainage method described above, the construction time is short, no noise is generated when the vehicle passes, it has excellent durability and can be used for a long period of time, and since it is not clogged, smooth drainage is always possible Since the road surface and the upper surface of the rubber chip binder present an integrated surface, the appearance of the road can be kept beautiful.
