Need for Innovation: Bridge engineers are seeking new ways to build better bridges, reduce work zone travel delays, and improve repair techniques thereby reducing maintenance. Additionally, owners are challenged with replacing critical bridge components (particularly bridge decks) during limited or overnight road closure periods. Precast panels manufactured from UHPC can provide signi?cant 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
Partial-depth precast concrete deck panels (PDDPs) are relatively thin precast prestressed concrete panels that span between girders which combine to ...
Using accelerated construction methods, a prestressed, precast bridge, was constructed the by Iowa DOT. The design concept involved the use of precast...
