Representatives of the members of the National Concrete Bridge Council (NCBC) give a series of presentations that focus on key elements of concrete bridge design and construction, including topics related to ABC. Some are covered in the AASHTO LRFD Bridge Design Specifications, while many concepts and practices are addressed through concrete industry publications. Speakers discuss recent state-of-the-art reports, industry manual updates, and other activities including recent developments in concrete solutions that are becoming more common practice in construction and renewal of concrete transportation projects. Presentations include discussion of how institute-based balloting and collaboration serve to establish consensus documents and certification programs that contribute to the body of knowledge within institutes and within the industry as a whole. Participants will receive industry handouts, presentations, and manuals.

Ultra-high-performance concrete (UHPC) has the potential to provide significant benefits in many applications for ABC due to its superior mechanical and durability properties. This workshop covers the basics of non-proprietary UHPC mix development, material properties, and applications of non-proprietary UHPC mix designs for ABC. It includes presentations on the need for non-proprietary UHPC, mix design development and material selection, non-proprietary UHPC material properties, effect of regionally available materials on mix performance, results of ongoing research sponsored by the ABC-UTC on structural behavior and durability of non-proprietary UHPC, and a summary of research conducted by other states and entities.

Steel bridges lend themselves well to accelerated bridge construction due to their reduced weight, which allows for smaller and less expensive construction equipment, and resistance to variable stresses during erection.  Steel is commonly used for ABC construction and this session explores a few examples from around the country, including a lateral slide on the New Pennsylvania Turnpike, a cost-effective press-brake-formed steel tub project with prefabricated decks in West Virginia, a 245-foot unbraced network arch in Michigan, and a compilation of several bridge projects from pre-engineered bridge manufacturers.

The focus of this workshop is performance of bridges built using ABC technologies in moderate-to-high seismic regions, with emphasis on seismic performance of connections. Developing seismic resilient connections that can accommodate inelastic deformations is the primary challenge for ABC in seismic regions. This workshop exhibits ABC technologies with self-centering precast concrete columns in seismic regions. Recent innovations in bridge design, materials, and construction meeting the post-earthquake functionality and serviceability requirements are presented. The workshop provides an opportunity for exchange of the latest information in research and implementation of ABC in seismic regions.

Non-Proprietary UHPC has the potential to be a viable option for ABC applications requiring performance exceeding that of conventional concrete. The differences in mixing, placement, finishing, curing, and testing methods required for UHPC compared to conventional concrete are best understood by practical exposure. This workshop will include demonstration of mixing, placement, and testing of non-proprietary UHPC with hands-on participation by the workshop attendees. It will also include a presentation on the upcoming ABC-UTC “Guide for ABC-UTC Non-Proprietary UHPC” and panel discussion that will identify important elements to consider when specifying non-proprietary UHPC
