Title:

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

Abstract:

Fixed Automated Spray Technology (FAST) is in use by the Colorado DOT's maintenance organization but the technology is rapidly changing with new design, hardware, software and installation techniques. 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. A specification was developed based on patterns of successes and failures in the development of FAST systems. Based on the lessons learned and the recommendations of this report, the new specification for FAST systems should be established. This report provides detailed recommendations on how to improve the design and construction of Colorado's bridge anti-icing systems. The research and recommendations in the report provide details for the planning, design, installation, and testing for future FAST system projects. This report should serve as an important resource to the DOT's maintenance personnel for both consideration and implementation of new FAST sites.
