Abstract: Sawing tool forms a surface structure on a road surface, has a shaft and number of diamond saw blades, each diamond saw blade has disc-shaped core with hole for placing on shaft. A segment is on outer circumference of core, and saw blades are arranged on shaft by disc-shaped core. Segments of adjacent diamond saw blades are in surface contact on longitudinal side, each segment formed from two layers adjoining one another in axial direction and extending in radial and axial direction. Axially adjoining layers of segment each have different wear resistances and wear resistance of layers in axial direction alternates over axially entire segment, so a furrow is formed by two layers adjoining one another, in order to set a grip and a noise level of the road surface. Axially adjoining layers of adjacent segments have different wear resistances forming an alternating layer structure over entire sawing tool.

Abstract: The invention relates to a sawing tool (7) for forming a surface structure on a road surface, at least having: a shaft (6) and a plurality of diamond saw blades (1), wherein each diamond saw blade (1) has a disc-shaped core with a hole for placing on the shaft (6), and a segment (3) which is arranged on an outer circumference of the core, wherein the diamond saw blades (1) are arranged on the shaft (6) by way of the disc-shaped core. The invention provides for the segments (3) of adjacent diamond saw blades (1) to be in surface contact on a longitudinal side (13), wherein each segment (3) is formed from at least two layers (8.i; i=1 . . . 6) that adjoin one another in the axial direction and each extend in the radial and axial direction, wherein layers (8.i; i=1 . . . 6) of the segment that axially adjoin one another each have different wear resistances (VF, VF1, VF2) and the wear resistance (VF, VF1, VF2) of the layers (8.i; i=1 . . .
