Friction measurements have been shown to successfully assess pavement conditions. Based on preliminary research, friction measurements could be used to assess the performance of various deicing agents and road treatment strategies as long as sufficient data is collected to fully document a variety of storms and deicing applications.  Field testing is needed to identify what, how, and when data should be collected (such as friction, temperature, timing, etc.) as well as how to analyze the data to assess deicer performance, optimal application rates, and investigate potential correlations to laboratory deicer performance. The objectives of this project are to develop a measurement and analysis tool to assess the performance of deicers in the field based on friction. The performance measure will be based on pavement friction before, during, and after deicer application.  Field tests will be conducted to develop and refine the methods of data collection and analysis.
