sometimes traffic stops completely. As a result of the deterioration of road travel in winter, the country's economy suffers significant social and economic losses (Holotiuk (2010)). Technologies currently used in the country to remove ice and compacted snow from road surfaces within the city most often involve salt mixtures. This ice-removing technology is not effective. This is because salt mixtures can cause vehicle metal surface corrosion, adversely affecting the road surface and car tires. In addition, if it gets into the soil, the mixture leads to wastewater pollution. If the ambient temperature is below – 10 0 C and the thickness of the ice formation exceeds 30 mm, salt cannot destroy it.

Considering the above, it is advisable to use equipment that would ensure cleaning of the coating without damaging it and without polluting the environment (Peng and Hu (2018); Doudkin et al. (2021); Moldakhanov et al. (2022)). A systematic study aimed at developing new working bodies for ice destruction or improving them requires knowledge of the mechanics of their behavior. The parameters of the working bodies of machines, and the energy consumption of the ice destruction process are determined by considering their physical and mechanical properties. The systematic study aimed at the development of new working bodies for ice destruction or their improvement requires knowledge of the mechanics of its behavior. The parameters of the working parts of the machines and the energy consumption of the ice cover's destruction process are determined based on its physical and mechanical properties. The analysis of the existing studies has revealed that many authors have investigated the properties of pure ice obtained artificially using distilled water (Wu and Prakash (2015); Weiss and Schulson (2000); Liu et al. (2022)). The results obtained by the authors do not consider the influence of foreign particles on the patterns of ice destruction. The works (Jordaan (2001), Montagnat et al. (2014), Kim and Kedward (2000), Schulson (2002)) are devoted to the study of ice deformation. The behavior of ice under compression and tension has been studied. In particular, Schulson (2002) established that ice destruction during compression is a complex process that occurs in stages: a crack originates during compression under plastic deformation conditions, grows, and expands over time. In addition to compressive deformation at the second stage, shear deformation appears. Studies of ice strength indices obtained under high-speed destruction differ significantly from those obtained in the quasi-static deformation regime (Combescur et al. (2011); Sain and Narasimhan (2011)). However, the study was performed with artificially created samples. In real conditions, the physical and mechanical properties of ice and its strength depend on specific local conditions the presence of inclusions, and therefore require additional experimental studies. The work aims at the experimental investigation of the ice impact destruction process using the wedge-shaped impact structural elements of the proposed ice crushing machine using physical models of ice blocks that meet the properties of the real ice cover on the roads of the Western region of Ukraine. The purpose of the research was to determine the physical parameters of destruction.
