There are two distinct snow and ice control strategies that have been gaining popularity and show promise in making use of chemical freezing-point depressants: de-icing and anti-icing. Anti-icing operations are conducted to prevent the formation or development of bonded snow and ice for easy removal, while de-icing operations are performed to break the bond of snow and ice and eliminate the buildup on the roads. See , “Materials,” for information on the various chemicals available to use in these operations.
