Extending the service life of concrete bridge decks can reduce maintenance costs and improve infrastructure resilience. TRB hosted a webinar on Friday, March 28, 2025 from 12:00 PM to 1:30 PM Eastern that explored innovative practices being implemented across the U.S. to enhance bridge deck durability and serviceability. Presenters discussed strategies to mitigate concrete deck deterioration caused by steel reinforcement corrosion, and share insights on materials, design techniques, and construction methods that improve longevity.
This webinar featured research from NCHRP Domestic Scan 22-01: Recent Leading Innovations in the Design, Construction, and Materials Used for Concrete Bridge Decks.
This webinar was sponsored by TRB’s National Cooperative Highway Research Program.
The slides are available. Please contact trbwebinar@nas.edu for a link to the recording. There may be a $90 fee.
