The dynamic strength of artificial ice (AL) for forest winter motor roads (FWMR) depending on temperature was studied. Technologies of layer-by-layer freezing with additives of polylactide (PLA) and potassium chloride (KCl) with sawdust are considered. Optimal PLA concentration (5-7%) was found to reduce AL thickness by 20-30%. Method of IL thickness calculation is proposed. The results are intended for the design of ALZD in regions with an unstable climate.
