BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing apparatus, and more particularly, to a wheel-type road surface crushing apparatus used for repairing road pavement.

Generally, pavement roads are divided into asphalt pavement roads and concrete pavement roads.

Asphalt paved roads have low construction cost and good ride quality, but they have low strength, so there is a lot of road breakage due to plastic deformation during use, and there is a disadvantage that they must be repaired frequently. Concrete paved roads are expensive in cost, It is advantageous that there is little road breakage and the maintenance cost is small.

However, the concrete pavement has a problem that the length is elongated and shrunk by heat, and the length thereof is finely changed according to the change of the ambient temperature, so that the road is broken.

Therefore, a joint having a predetermined width and depth is formed on the concrete pavement road in order to prevent the road from being damaged due to elongation and contraction due to temperature change.

The joint is divided into a horizontal joint which is cut at a predetermined interval across the horizontal direction of the road surface and a vertical joint which is formed at a predetermined interval with the vertical direction of the road surface perpendicular to the horizontal joint.

The horizontal joints and vertical joints that are buried in the concrete slab of the concrete road are injected with a viscous and sticky liquid joint material such as silicone to prevent rainwater, snow and the like from being introduced into the interior.

That is, when rainwater or snow flows into the horizontal joints and vertical joints, the interior of the concrete continues to be wet and durability is lowered. This wet state is frozen in winter and its volume expands, causing cracks in the concrete pavement This is to prevent this.

Generally, the joint of the concrete pavement is formed by cutting a horizontal joint and a vertical joint with a cutting machine, and then injecting and filling a liquid joint into the horizontal joint and the vertical joint which have been cut to a predetermined depth.
