Abstract:This research project evaluated the construction and performance of Boschung’s Fixed Automated
Spray Technology (FAST) system. The FAST system automatically sprays de-icing material on
the bridge when icing conditions are about to occur. The FAST system includes the installation of
a Road Weather Information System (RWIS) to monitor the roadway and weather conditions. The
data collected from the RWIS determines if the de-icing material should be released on the bridge
deck. The roadway sensors are programmed to submit to the RWIS a temperature reading up to
three degrees less than the actual temperature, so the de-icing material is dispensed in anticipation
of icy conditions. The FAST system provides a benefit to the traveling public, since de-icing
materials are deployed at the appropriate time to prevent hazardous road conditions. The
Department would receive a benefit with de-icing material being deployed only when required,
instead of pre-treating in anticipation of freezing conditions.
