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…6) in the axial direction alternates over the entire segment (3), wherein a furrow is able to be formed in each case by two layers (8.i; i=1…6) that axially adjoin one another, in order to set a grip and a level of noise of the road surface, and layers (8.i; i=1..6) that axially adjoin one another of adjacent segments (3) have different wear resistances (VF, VF1, VF2) in order to form an alternating layer structure over the entire sawing tool (7). |
