Method and device for working of road surfaces

A device for working of road surfaces, such as planing of road having gravel or oil-gravel surfaces and ice-scraping, comprising a mounting plate for attachment to a machine for working of the road surface, and a plurality of wear elements having tips arranged in a row on said mounting plate, wherein the wear elements are rotatably mounted on the mounting plate to remove material from the road surface to a substantial extent by crushing the material under rolling contact between the tips and the road surface.

A device for working of road surfaces, such as gravel or oil-gravel surfaces and ice scraping, comprising a plurality of wear elements adapted to displace material from the road surface, wherein the wear elements are rotatably mounted in a supporting device, said supporting device including a base member and a holder body with said wear elements being mounted in a row on said holder body, said base member having means for mounting said supporting device to a driving means for working said road surfaces while permitting substantially only linear movement of said support device, the wear elements rotatable relative to the road surfaces.

A cutter means for working of road surfaces comprising a support device including a base member and a holder body, means for mounting said support device on a driving means for permitting substantially only linear movement of said support device, such as planing of roads having gravel or oil-gravel surfaces and ice-scraping of roads, wherein a plurality of tools in the form of wear elements are rotatably mounted in the holder body, said wear elements being mounted side by side and having tips for the working of the road surface, the wear elements being of generally longitudinal shape with the tips extending substantially beyond the holder body so as to be contactable with the road surfaces in the absence of said support device contacting said road surfaces.
