Self-Consolidating Concrete for Connecting Precast Concrete Deck Panels and I-Girders

Existing precast concrete deck systems are either partial depth or full-depth with open channels/pockets that require cast-in-place concrete and deck overlay. There operations negatively affect the quality and speed of construction, which are the main goals of using precast deck systems. The Kearney East Bypass in Kearney, NE is the first bridge project that uses the latest developments in full-depth precast concrete deck systems for precast/prestressed concrete girder bridges. These developments include using full-depth full-width deck panels with covered individual pockets at 4 ft spacing eliminating the need for deck overlay or exposed cast-in-place concrete. Self-consolidating concrete (SCC) is vital to the success of the new deck system to fill the deck pockets and the large gap between the deck soffit and precast concrete girders without the need for expensive commercial grouts. A research project titled "Implementation of Precast Deck Panel NUDECK" is currently being conducted at the University of Nebraska - Lincoln (UNL) and sponsored by Nebraska Department of Roads (NDOR) to address design and detailing of the new deck system to be implemented in the Kearney Easy Bypass by the end of 2013. However, the constructability of the developed deck system needs to be investigated to improve its competitiveness against cast-in-place concrete decks.
