A Synthesis to Improve the Design and Construction of Colorado's Bridge Anti-Icing Systems

Fixed Automated Spray Technology (FAST) is currently in use by the Colorado Department of Transportation’s (CDOT’s) maintenance organization but the technology is rapidly changing with new design, hardware, software and installation techniques. The existing specification is not current. This study was designed to develop a state-of-the-art specification for statewide use. Available information on CDOT’s existing FAST sites was reviewed, along with information from other state, city and county, and European agencies, to design a document that can be updated as the technology develops. Research from a survey document sent to 50+ agencies using FAST system technology, global internet search results, personal interviews, and documented reports were used to develop a specification based on patterns of successes and failures in the development of FAST systems. Based on the lessons learned from the work described above and the recommendations of this report, the new specification for FAST systems should be established.
