Description
This session examines the assessment and repair of segmental bridges and their components. Due to their design and unique components, assessments of segmental bridges require evaluations that are not typically performed in other bridges. This includes locating voids of grouted tendons, examination of post-tensioned tendon corrosion, and verification of as-built conditions. This session will include case studies that bring to light recent advances in the assessment and repair methods of segmental bridges.
