| Résumé : |
The Minnesota Department of Transportation conducted a one-day seminar on bridge maintenance painting strategy and project design in May of 2013. One outcome of that seminar was the realization that MnDOT needed a more uniform method to rate the condition of coatings statewide during biennial bridge safety (in conjunction with the new AASHTO Manuel for Bridge Inspection) as well as a process to select and prioritize maintenance painting strategies. MnDOT assembled a Technical Advisory Panel to address the needs identified during the serninar and launched a multi-objective study in October of 2013, This article describes the outcomes of efforts undertaken and MnDOT's novel approach to improving statewide bridge maintenance painting operations.
