Snow & Ice Circles

Snow and Ice circles for repeatable constant radius testing

Our facility includes multiple snow and ice circles designed to provide repeatable and controlled constant-radius test conditions. Snow circles range from R40 m to R140 m in radius, with level, packed snow surfaces prepared to a CTI of 80–90, ensuring consistent low-friction performance for the evaluation of lateral control systems. For extremely low-mu testing, polished ice circles R20 m to R40 m are available, typically prepared to a coefficient of friction of 0.1 Mu or lower. Custom surface preparations and radius configurations can be provided to meet specific test program requirements upon request.
