The Science of Roadway Ice Control (Group)


Created by: John Ryynanen


Ice control materials – including sodium chloride, calcium chloride, magnesium chloride, and others – have unique characteristics that determine their effectiveness in different situations. With a basic understanding of the science of ice control materials, plow operators will be able to deice roads more effectively. This short training module covers:

  • Binary phase diagram
  • How deicers work
  • Dilution cycle
  • Hygroscopic characteristics
  • Endothiermic vs. Exothermic
  • Effective temperatures of common deicers
