<p>On the track grid (14) and/or on the bedding material (16) are horizontally arranged, adjacent form bodies (22,28) on a rubber basis. At least one part of the form bodies (22,28) contains hard material particles (27), at least in a layer adjacent to the traffic-loaded surface. The hard material particles (27) in the new state, or after short-time usage, remain free on the traffic-loaded surface and/or extend out of it. The hard material particles (27) are of corundum, metal carbide and/or metal nitride and/or metal oxide. They are coated with an organic adhesive layer. partic. an artificial resin adhesive layer, esp. polyolefin.</p> |
