Simplified Full-Depth Precast Concrete Deck Panel Systems
TRB’s National Cooperative Highway Research Program (NCHRP) Research Report 895: Simplified Full-Depth Precast Concrete Deck Panel Systems describes new connections between full-depth precast concrete deck
panels and beams. These connections are simplified with regard to constructability,
inspection during construction, reducing the impact of construction on traffic, and future
deck replacement.The
new system utilizes clustered shear connectors spaced up to six feet and connected to the deck
system using ultra-high performance concrete. It also utilizes
discrete joint connections to eliminate blind grouting. This report also presents proposed revisions to the AASHTO Bridge Design Specifications.
