This paper presents, in considerable detail, an approach used to assign priorities to bridge
decks for protection, rehabilitation, or replacement. The system was developed by
integrating traffic use (level of service) with existing deck condition. High priority is assigned
to critically deteriorated decks in heavy and moderate traffic volume locations. Medium
priority is assigned to exceptionally good decks in heavy and moderate traffic volume areas
to prevent chloride-induced corrosion of the rebars and subsequent spalling. Low priority …
This paper presents, in considerable detail, an approach used to assign priorities to bridge decks for protection, rehabilitation, or replacement. The system was developed by integrating traffic use (level of service) with existing deck condition. High priority is assigned to critically deteriorated decks in heavy and moderate traffic volume locations. Medium priority is assigned to exceptionally good decks in heavy and moderate traffic volume areas to prevent chloride-induced corrosion of the rebars and subsequent spalling. Low priority schedule are reviewed and discussed. The rationale for selecting protection systems to be installed and the deck preparation rquired for various initial deck conditions is presented. Last, a brief review of policy implementation is provided.(Author)
