Spreading salt on road surfaces is one of the primary means for removing and preventing accumulation of snow and ice. The Iowa Department of Transportation (Iowa DOT) has a new management dashboard that helps winter maintenance decision makers efficiently use salt resources. The "Salt Dashboard" is an automated web-based tool that compares the amount of salt used by each garage to targets based on salt application rate guidelines, weather information, lane miles, and level-of-service expectations. The Dashboard can also provide analysis on a district or statewide level.
Iowa DOT reported that after the agency started using the Salt Dashboard in 2012, the state saves more than $2.7 million annually on salt.
