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.
