Frictional Characteristics of Sand and Sand-Deicer Mixtures on Bare Ice
Frictional characteristics of sand and sand-deicer mixtures were investigated as functions of temperature, gradation, and application rate. This report presents results of a laboratory coldroom study measuring sliding friction using a British pendulum tester. Four temperatures, three sand gradations, four brine concentrations, and four sand-application rates were investigated. All tests were performed on an ice sheet inside a cold room, where sand temperatures were maintained close to ice temperatures. Three categories of materials were tested: sand alone, sandsalt mixes, and sand-brine mixes. Results showed that sand-brine mixes outperformed the other two, with significantly greater sliding friction.
