For over 40 years we have sought after a measure of friction during winter events to determine if additional treatments were required. Over the decades the science, sensors, and computing power have advanced to the point that friction or grip is making its way into winter operations.
On this episode we explore some cutting edge work in world of winter road friction. Lead Statewide Snow & Ice Engineer for the MassDOT Mark Goldstein and from the Research Applications Lab at the National Center for Atmospheric Research, Senior Software Engineer Gerry Wiener and Software Engineer Seth Linden discuss projects they are involved with and the finer points associated with using friction/grip in winter maintenance.
