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.
