The article discusses the possibility of increasing the efficiency of the working attachments of road machines and their adaptation to work in various conditions, due to the group equipping with single saw blades placed according to specially developed schemes. The main results of studies of the processes of interaction of a saw blade moving in space with a variable speed with ice during its mechanical destruction are presented. The conditions for conducting experimental studies, the composition and general structure of the main and auxiliary laboratory equipment used are described. The main results of laboratory research are stated. Taking these results into account, the specific energy intensity of the process under study was calculated, the graphs of the dependence of the specified parameter on the cutting speed were plotted, and conclusions were formulated on the work. The substantiation of rational operating parameters of saw blades is given, which ensure the minimum specific energy consumption of the process under study.
