Improving The Freight Transportation Roadway System During Snow Events: A Performance Evaluation Of Deicing Chemicals, Christopher Y. Tuan Ph.D., Barbara M. Gerbino-Bevins

Christopher Y. Tuan

The ability of state DOTs to adequately clear roadways during winter weather conditions is critical for a safe and effective freight transportation system. Variables affecting winter maintenance operations include the type of precipitation, air and pavement temperature, traffic, wind, time of day, day of week, and maintenance equipment. The main objective of this study is to identify the best practices for normal deicing operations, based on the performance rating of deicing chemicals. Optimum deicer/brine ratios and the associated application rates will be determined for various weather conditions. The best practices will ensure effective deicing operation and economical use of deicing …
