![]() ![]() This work presents a synthesis of relevant information in the published domain, with a focus on the traditional and innovative strategies potentially useful for highway agencies to fight extremely cold storms. In this context, it is necessary to examine the best practices of highway winter maintenance operations with a renewed perspective, so as to target these extreme storms. The most severe 20 percent of the storms can cost 80 percent of an agency’s annual budget for winter maintenance. To achieve a drivable pavement friction condition, excessive amount of plowing, chemicals, and/or abrasives is often used, which leads to substantial cost increases and environmental concerns. ![]() ![]() ![]() Once the pavement temperature drops below 10☏, the traditional tools (e.g., granular salt) become ineffective. Such activities become essential when a storm with extremely cold temperatures hits the area, either as a result of normal fluctuations or as a result of climate change. Winter maintenance operations are crucial for achieving a reasonable level of motorist safety and public mobility on highways in cold regions. ![]()
