DURABILITY SURVEY OF SEGMENTAL CONCRETE BRIDGES
In the early 1990s, the American Segmental Bridge Institute (ASBI) initiated an inventory of concrete segmental bridges built in the United States and Canada. The survey questionnaire identified 194 structures by type and age. To assess their performance over time, the ASBI evaluated 96 bridge inspection reports that rated bridge conditions using Federal Highway Administration (FHWA) guidelines. With construction completion dates ranging from 1966 to 1993, all of the bridges with inspection reports received superstructure condition ratings of "fair" or better. More significantly, 98% of the bridges rated "satisfactory", 84% "good", and 47% "very good". The findings overwhelmingly indicate that concrete segmental construction performs well over time. This report on the durability survey of these bridges provides a brief history of segmental construction, an overview of the segmental concrete bridge inventory, a summary of the inspection report, comments on overall bridge conditions, and bridge condition case studies from four states.
