Use with RWIS

Anti-icing can be more effective when coupled with a Roadway Weather Information System (RWIS). An RWIS helps to make informed decisions about when and where to deploy materials, crews and equipment.
While an anti-icing strategy coupled with an RWIS can be beneficial, there are some drawbacks associated with RWIS:
  • high initial cost
  • potential for premature and/or unnecessary application of materials
  • insufficient sensors/stations and the incompatibility of RWIS platforms
  • overapplication of chloride-based chemicals can result in slick pavement
  • high maintenance and upkeep costs.
