る。2. Description of the Related Art A pavement surface is polluted by various causes such as accumulation of mud and dust. Among the contamination of pavement road surface, for example, rubber residue derived from tires and paint pieces derived from lines and road markings drawn on the road surface are firmly attached to the road surface and are difficult to remove by normal cleaning work. It is a thing.

必要がある。When rubber residue or the like accumulates on the pavement surface, a black striped pattern is formed at that location. Not only is this striped pattern unsightly, but rubber residues accumulated in the black areas reduce the friction coefficient of the road surface, which contributes to the extension of the runway distance during takeoff and landing at the airport, and the reliability of the driving data on the car test course. Is also damaged, and it may cause a slip accident even on public roads, especially in bad weather. Therefore, it is necessary to remove the rubber residue and the like adhering to the pavement surface before a certain amount is accumulated.

ある。[0004] Attempts have been made in the past to remove adhered rubber residue and deteriorated road markings by polishing the paved road surface. For example, JP-A-49-112293 describes a road traffic sign grinder equipped with a belt grinder. However, the belt grinder has a problem that it is poor in tracking the three-dimensional shape.

てしまう。In general, a large number of fine uneven shapes are formed on the paved road surface to maintain the friction property. Here, when the road surface is polished with an abrasive material having poor flexibility such as a belt grinder, even fine irregularities on the road surface are scraped off, and the frictional property of the road surface is impaired. In particular, rubber residue and the like need to be removed in order to get into the uneven eyes and hinder the frictional resistance of the road surface, but if the road surface is ground to the inside of the eyes with a rigid abrasive, the uneven shape itself is removed. This will damage the road surface.

The paved road surface referred to in the present invention includes all road surfaces paved with conventional paving materials such as asphalt, concrete, brick, and tile. The pavement road surface is macroscopically flat or gently curved, but microscopically has many fine irregularities.

Microscopically, the wall surfaces of these structures also have fine irregularities. In order to maintain the structure of the building, it is necessary to clean the wall surface of the building so as not to damage the fine uneven shape, and this is common to the paved road surface in this respect. Therefore, in the present invention, the outer surface of a building made of concrete, bricks, tiles, or the like can be included in the concept of paved road surface. Further, it is also used for cleaning unnecessary objects (cement powder or the like used for connecting aggregates) existing on the surface of a newly paved road surface after construction.

The nonwoven abrasive has a porosity of 20 to 97%, preferably 50 to 95%. When the porosity is less than 20%, the conformability to shape deformation due to the unevenness of the road surface is lost, and when it exceeds 97%, the material consumption rate becomes extremely high, and it becomes unusable in actual use. Further, Shore D hardness is 20 to 90, preferably 50.
~ 90. If the Shore D hardness is less than 20, the cleaning ability will be extremely reduced, and if it exceeds 90, even fine irregularities on the road surface will be removed, and the road surface will be damaged.
