Anti-icing with brines is generally not recommended around rain, but how does this extend to solid (pre-wetted) salt around freezing rain? This presentation will discuss recent experimental and modeling work to better understand the dilution rate of pre-wetted salt and provide insight on its applicability for anti-icing under freezing rain conditions. Proficiency Level: Advanced Session Evaluation: https://www.surveymonkey.com/r/XKK5HC6 By attending this session, participants will be better able to:
• Predict (to a first approximation) the anti-icing effectiveness time of solid salt exposed to freezing rain.
• Identify the major factors affecting anti-icing effectiveness duration under freezing rain.
• Predict (to a first approximation) pre-wetted salt application rates based on pavement temperature and rainfall rate.
