At what temperature range should brine be applied to roadways?

Brine is typically used for de-icing and anti-icing purposes on roadways. The ideal temperature range for applying brine is critical for its effectiveness. When applied between 28 degrees to 32 degrees Fahrenheit, brine can effectively prevent ice from forming and help in melting existing ice. This range allows for the optimal performance of the brine solution, as it interacts well with the snow and ice at these temperatures.

Brine solutions work by lowering the freezing point of water, which helps in melting ice on road surfaces. At temperatures above freezing, while the brine can still work, the success might be limited due to the potential for rain or warmer temperatures diluting the impact. Conversely, below 28 degrees Fahrenheit, brine tends to be less effective, and its ability to prevent freezing may diminish as temperatures drop further, making other methods more suitable for ice control. Thus, using brine within the specified range ensures maximum efficiency in roadway maintenance during winter weather conditions.
