Experiments were carried out with physical models of ice formations on the roads of the Western regions of Ukraine that were obtained under different temperature conditions during four experimental periods. The patterns of influence of the block thickness, its temperature, as well as the shape of the impact of destructive elements on the ice destruction have been established. The dependence of the conditional depth of a wedge-shaped destructive element immersion into the body of the ice block on its thickness at different temperatures has been constructed. Oscillograms of shock pulses were obtained, which serve as the basis for determining the parameters of shock destruction of ice. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction Winter is a challenging and demanding period for road maintenance services due to the fact that road conditions during this period are often the cause of road accidents. Phenomena that make road travel difficult or impossible include blizzards, snow drifts and icy pavements. The latter causes a significant decrease in the traffic speed, and Abstract The process of rupture of ice blocks of different thicknesses by destructive impact elements in laboratory conditions was experimentally studied.
