Among the new techniques being tried are liquid blends; using two different chlorides and adding carbohydrate liquids to brines; using advanced systems to ensure trucks are loaded correctly with the right materials and the right quantities; and using liquids to create slurries at high pre-wetting rates.

  • Identify the cost benefits of using blended liquids.
  • Explain the environmental impacts of some anti-icing and deicing techniques.
