This study evaluates various bridge-coating systems and recommends an alternative coating system to meet all environmental regulations and satisfy INDOT's performance requirement. The identified coating systems will be compared with INDOT's current system of inorganic zinc and vinyl to verify benefits of the newly recommended system. The analysis procedure will be performed through extensive literature search, expert interviews, test results from government agencies, discussion with paint manufacturers, and collection of experiences from bridge owners across the country. The problems facing the current system are observed and the evaluation of overcoatoing alternative is presented. |
