摘要

The method involves providing a grit which is yielded from grit particles, distributing the grit particles over snow or an ice surface (2) which is blunted and blunting the snow or ice surface, frozen by the strewing particles on the snow or ice surface in a surface-laterally managing condition. An independent claim is also included for a device for yield of grit on snow or ice surface.
