Salt brine is used as a prewetting agent for solid salt and anti-icing operations.
In an anti-icing mode, brine is applied to the pavement before or at the start of a storm to prevent the formation of a bond between packed snow and the roadway surface on continuous treatment routes. The application rates for salt and salt brine depend on temperature and amount of snowfall. TOP Communications and Public Outreach MoDOT contracts for a weather forecast service during the winter season. In addition to a daily forecast, the service provides each district office with advisories and warnings for winter storms that may affect their area. In addition to the contract service, district offices make use of the weather channel and local weather forecasts to provide information on approaching winter storms.
