This research project evaluated the construction and performance of Boschungs 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.
