Salt brine is best used to pre-treat the roads in anticipation of winter storms. Salt brine can prevent ice on the road for up to three days in advance of a snow / ice storm. The salt brine will begin working as soon as the first snowflake falls and will delay the accumulation of snow and ice on the pavement due to lowering the freezing temperature. Salt brine can be applied when the temperatures are between 15 degrees and 32 degrees Fahrenheit, but works at temperatures down to 0 degrees Fahrenheit. Typically, once a storm event is forecasted, the Department of Public Works will pre-treat with salt brine during a normal work day, thus reducing the need for additional overtime.
