The ice ride-up and ice gouging processes are related to the interaction between ice and sand or gravel. The friction coefficients of ice with those materials are important factors in calculating loads during these processes. However, there is little information available on these friction coefficients. Therefore, tests on the friction between saline ice and sand were conducted in an indoor cold chamber to evaluate the static (μ_s) and kinetic (μ_k) coefficients of friction of ice on sand as functions of the normal stress, temperature and other variables. This paper examines the results of those tests.
