Best Practices Manual for Quality Bridge Coatings
FHWA has expended significant resources on developing advanced corrosion-protection materials and applications for bridge structures over the past 20 years. Much of this work has focused on development of materials-based solutions. While there is still potential for greater performance in the materials area, the returns from these efforts are diminishing. Much more promising are efforts that seek to elevate the level of quality achieved during actual application of advanced corrosion-protection methods and materials. These reports document best practices in contracting (e.g., warranties, rapid turnaround), training and certification, and specific quality control/quality assurance mechanisms.
