CONSTITUTION:An aggregate having one to several kinds of protrusions 1, e.g. conical, cylindrical, pyramidal and prismatic, projecting back and forth, left and right, vertically or obliquely is used. a proper amount of the aggregates are mixed in such a paving material as rubber, asphalt and cement when a paving rubber sheet or a paving block is provided, the aggregates 1 are projected from the necessary surface 6 of the paving rubber sheet or block to form a paving material. When the material is used, the road surface to be paved is appropriately heated, the surface 6 having the protrusions 1 is abutted on the road surface, the material is pressed downward, and the protrusions 1 bite into the asphalt on the road surface at respective angles and are wedged into the asphalt.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aggregate for enhancing the strength of a pavement road surface by mixing with an asphalt or cement pavement material and a pavement material for a rubber plate for paving or a block for paving, which can be directly attached to the road surface. It is about.

[0002]

2. Description of the Related Art For pavement of a road surface, asphalt is mainly melted in a mud form, and an appropriate amount of aggregate such as gravel, crushed stone, and stone powder is mixed, and a paving pressure is applied to the road surface. With the increase of cars,
The vibration of cars running on the paved road affects residents and buildings along the railway line, and there are many complaints about the vibrations of the residents along the railway line.
There has been no method to prevent the vibration of the road surface, but recently, a method of attaching a rubber plate or a block mixed with rubber to the paved road surface to reduce the vibration has been considered.

[0003]

[Problems to be Solved by the Invention] The pavement of a road surface by melting the asphalt in a mud form and mixing aggregates such as gravel, crushed stone, and stone powder causes the road surface to soften at high temperatures, causing the road surface to wavy or cool. The simple pavement that caused cracks and peeling due to cracks and did not maintain the road surface foundation had the drawback that cracks and peeling occurred and holes were likely to be formed. In order to reduce the vibration of the road surface caused by the car traveling on this paved road surface, a method of sticking a rubber plate to the road surface in order to absorb the vibration is considered, but use an adhesive as the sticking method. However, there is no adhesive that can stick a rubber plate on the road surface, and there was no way to effectively stretch the rubber plate on the road surface. Further, since the rubber plate has a high expansion and contraction rate due to the temperature difference, it is not stable on the road surface, the rubber surface is slippery and dangerous, and the rubber wears quickly and there is a problem in durability. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide an aggregate that enhances the strength and durability of a pavement surface and a pavement material that effectively wedges onto the pavement surface and can absorb vehicle vibration.

[0004]

In order to achieve this object, the present invention has the following configuration. 1. The aggregate according to the present invention forms projections made of at least one kind or several kinds of free shapes such as a cone, a cylinder, a pyramid, and a prism that project in any direction such as front, rear, left and right, up and down, and obliquely. 2, the pavement material according to the present invention, front and rear, left and right of claim 1,
At the stage of manufacturing paving rubber plates and paving blocks, aggregates with projections consisting of at least one or several types of cones, cylinders, pyramids, prisms and free shapes protruding vertically and diagonally in any direction are manufactured. , Rubber, asphalt, cement is mixed in an appropriate amount in the paving material, and the protrusions of the mixed aggregate are appropriately projected on the required surface of the paving rubber plate or paving block.

[0005]

[Action]

1. When an appropriate amount of the aggregate of the present invention is mixed with asphalt or paving material, the protrusions of the aggregate are entangled with each other to increase the engagement with the asphalt or paving material, and when paving the road surface with this, the strength and durability of the paved road surface It is possible to prevent flow by increasing the friction resistance function. 2. By mixing an appropriate amount of the aggregate of the present invention into a pavement rubber plate or a pavement block, the protrusions of the aggregate are entangled with each other and the rubber and the pavement material are engaged with each other to increase strength and durability.
Also, on the required surface of the paving rubber plate or paving block,
By appropriately protruding the protrusions of the mixed aggregate,
By only pressing the protruding surface of the projection against the road surface, the projection bites into the asphalt on the road surface from each angle, and the rubber plate for paving or the paving block wedges on the road surface.

Embodiments of the present invention will be described below with reference to the drawings.

First Embodiment A first embodiment of the present invention will be described with reference to FIG. This aggregate is made of a material such as ceramic or metal, and is composed of a plurality of protrusions 1 of appropriate length protruding in any direction such as front, rear, left, right, top, bottom, and diagonal, and the protrusion 1 is a cone. It has a shape. To use this aggregate, it is advisable to mainly melt asphalt into a mud form, mix an appropriate amount of the aggregate of the present invention with gravel, crushed stone, stone powder, etc., apply paving pressure to the road surface, and pave the road surface.

Second Embodiment A second embodiment of the present invention will be described with reference to FIG.
