Full Depth UHPC Waffle Bridge Deck Panels

Bridge engineers are seeking new ways to build better bridges, reduce work zone travel delays, and reduce maintenance costs. Agencies are challenged with replacing critical bridge components with minimum disruption to the traveling public. Using ultra high performance concrete, or UHPC, for precast panels and connection details is a new application that offers great potential for new and rehabilitation bridge projects around the country. Wapello County, Iowa was familiar with UHPC and saw its potential. With the help of an FHWA Highways for LIFE Technology Partnerships grant to Coreslab Structures, they used UHPC waffle design modular panels and UHPC connections for their Little Cedar Creek bridge project. The bridge consists of 14 waffle slabs. The bridge deck panels were manufactured with UHPC and were installed with field cast UHPC connections for bridge deck continuity. The design is simple, manufacturing is easy, and construction moves quickly. The lightweight panels will allow rehabilitation without needing to strengthen the substructure to handle heavier live loads. It also will be possible to rehabilitate a bridge under traffic by replacing one lane at a time.
