The use of liquid brine is more effective at keeping highways safe during the winter months, a new report says.
Researchers from the University of Wisconsin – Madison’s Traffic Operations and Safety (TOPS) Lab looked at data from 143 storms occurring in 10 counties across Wisconsin. It compared brine-cleared routes to those nearby cleared with a traditional granular rock-salt method. The researchers found use of liquid brine in winter highway maintenance cleared Wisconsin highways faster, provided better friction on roadways, and reduced overall salt usage.
