COMPARATIVE ANALYSIS OF TECHNICAL AND ECONOMIC INDICATORS OF THE OPERATIONAL EFFICIENCY OF MACHINES FOR ANTI-ICE TREATMENT OF PAVEMENTS

Abstract

The article touches upon one of the most important problems associated with the winter maintenance of road construction elements (sidewalks, footpaths), namely, winter street injuries of pedestrians. As one of the possible solutions to this problem, a disk distributor with a symmetrical method of supplying solid anti-icing material to the disk is proposed for operation, which provides a better distribution compared to the traditional asymmetric method of supply. It is assumed that this equipment will be installed on the base machine – a typical distributor of anti-icing materials along the carriageway. The article carried out a comparative technical and economic analysis and evaluation of the technical and economic indicators of the operation of machines in order to select the most effective combination of machines for de-icing the roadway and sidewalks. Six models of machines were selected for analysis, similar in their technical characteristics to real machines used for the distribution of solid anti-icing materials. As a criterion for the efficiency of operation, the cost of production of work, the annual volume of work and operational shift productivity were chosen. As a result of the analysis, it was found that the operation of combinations of machines, including a disk distributor with a symmetrical feed method, will allow achieving higher technical and economic indicators due to a slight increase in the cost of production of anti-icing coatings.
