Full Depth Ultra High Performance Concrete (UHPC) Waffle Bridge Panels. Bridge engineers are seeking new ways to build better bridges, reduce travel times, and improve repair techniques; thereby reducing maintenance. Precast panels manufactured from UHPC can provide significant durability improvements to bridge decks due to the high strength, extremely low permeability, and improved connection details inherent in the system. The use of this innovation will result in reduced construction time for new and rehabilitated bridges, the ability to upgrade the load carrying capacity of existing bridges, and improved durability of bridge decks. Award amount $382,971.
