Abstract
The invention concerns a device for wear testing to test wear on road surfacings, said arrangement including a cylindrical test piece 12 made of a material to be tested and at least one abrasion wheel 8 that is arranged to be able to be pressed against the cylinder surface 13. According to the invention the device includes displacement devices 15, 17 to displace the test piece and abrasion wheel relative to each other to prevent the abrasion wheel from running along the same track on the surface of the test piece. <IMAGE>
