Menetelmä ja hiekoituslaitteisto tien tai vastaavan hiekoittamiseksi

摘要

The subject of the invention is a device and a process for sanding a road or equivalent, according to which process the sand is spread from a moving vehicle 3 over the desired width, thereby creating a sanded carriageway. The sand is fastened to the icy ground 11 by heating of the sand particles, whereupon they melt a cavity for themselves in the ice layer. A friction and pressure action is directed at the ground 11 either immediately prior to the spreading or following the spreading. <IMAGE>
