This workshop will be a follow-up to the ABC-UTC pre-conference workshop held in 2017. The goal will be to cover the design of common ABC details and methods including prefabricated deck connections, precast integral abutments, precast piers, and SPMT and lateral slide systems.

Workshop Coordinator: William Nickas, NCBC
Speakers: Reid Castrodale, ESCSI; Pete Fosnough, EIG; Gregg Freeby, ASBI; Todd Hawkinson, WRI (invited); Brian Killingsworth, NRMCA (invited); Danielle Kleinhans, CRSI (Invited); Tony Kojundic, SFA; William Nickas, PCI; Alpa Swinger, PCA; Miroslav Vejvoda, PTI (invited)

Representatives of National Concrete Bridge Council (NCBC) membership will 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 will 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 will 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

Speakers (invited): Atorod Azizinamini, FIU; Royce Floyd, OU; David Garber, FIU; Mohamed Moustafa, UNR; Behrouz Shafei, ISU; John Stanton, UW; Jeffery Volz, OU

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 will cover the basics of non-proprietary UHPC mix development, material properties, and applications of non-proprietary UHPC mix designs for ABC. It will include 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, and results of ongoing research sponsored by the ABCUTC on structural behavior and durability of non-proprietary UHPC.

Afternoon Sessions

Wednesday, December 11, 2019 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator: Jeff Carlson, NSBA
Speakers: Joe Hardee, EOR, AECOM (Invited); Andrew Palahnuk, PM, Archer Western (Invited); Jorge Suarez, CM, Michael Baker International

I-95 is a north-south interstate highway that crosses through Richmond and Henrico County, Virginia. Eleven bridge rehabilitations will be performed using state-of-the-art accelerated bridge construction techniques. All the bridge superstructures will be constructed off site and delivered to the bridge locations with specialty transport trailers. Unique prefabricated bridge superstructure units, night-time lane closures and crossovers using zipper barrier system, bridge replacements, public involvement, MOT schemes and haul route coordination and permitting.

Wednesday, December 11, 2019 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator: Bijan Khaleghi, WSDOT
Speakers (invited): Atorod Azizinamini, FIU; Waseem Dekelbab, TRB; Marc Eberhard, University of Washington; Mark Gaines, WSDOT; Zachary Haber, FHWA; Eddie He, Parsons; Elmer Marx, Alaska DOT&PF; Mustafa Mashal, Idaho State University; Pinar Okumus, University of Buffalo; Tom Ostrom, Caltrans

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 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.

Wednesday, December 11, 2019 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator: Mike Culmo, CME Associates Inc.
Speakers: Mike Culmo, CME Associates Inc

This workshop will cover the long-term performance of commonly used ABC details. Case studies of older ABC projects will be presented dating back to 1990. The performance of ABC technologies used in Utah will be covered based on 10 years of performance inspections of ABC projects including precast full-depth deck panels, precast integral abutments, precast piers, and SPMT and lateral slide systems. The presentations will cover good detailing practices and materials specifications that will lead to good long-term performance.

Wednesday, December 11, 2019 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator: Royce Floyd, OU
Demonstration Leaders (invited): Royce Floyd, OU; David Garber, FIU; Trevor Looney, OU
Panelists (invited): Atorod Azizinamini, FIU; Royce Floyd, OU; David Garber, FIU; Mohamed Moustafa, UNR; Behrouz Shafei, ISU; John Stanton, UW

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 ABCUTC Non-Proprietary UHPC” and panel discussion that will identify important elements to consider when specifying non-proprietary UHPC.
