Organic Zinc-Rich Paint System Research Project Number 85-102. Windgap,Sutersville and Hillcrest Bridges. Phase 4 Final Report

摘要

This report assesses the performance (over a five-year period) of an experimentalorganic zinc-rich paint system applied to the Windgap, Sutersville, and Hillcrest Bridges. This final report for the study includes: Summary of all field data collected for Phases II (coating installation and initial evaluations) and III (annual performance inspections over a five-year period); Coating system evaluation; Comparison of the experimental system performance to existing bridge coating systems; Maintenance painting cycle for the next 15 years to achieve an overall 20-year life of this system, as well as life cycle costs for comparison purposes to other systems; Recommendations; Coating specifications.
