The AASHTO re:source podcast recently interviewed Professor Atorod Azizinamini from Florida International University about designing for service life rather than just strength and how ultra-high performance concrete (UHPC) can improve resiliency and bridge construction processes.

AASHTO re:source – which launched this podcast series in September 2020 – is part of the engineering and technical services division of the American Association of State Highway and Transportation Officials.
It provides services and tools through three major programs: the Laboratory Assessment Program, the Proficiency Sample Program, and the AASHTO Accreditation Program.
Professor Azizinamini is the Vasant H. Surti Professor of Civil Engineering for the university and serves as the director of the Moss School of Construction as well as the director of the Institute for Resilient and Sustainable Coastal Infrastructure, known as “InteRaCt.”
He is a licensed professional engineer, received a Ph.D. from the University of South Carolina-Columbia in 1985, and specializes in structural and bridge engineering.
UHPC is a more resilient material than typical concrete, made with steel fiber reinforcement throughout, a specific aggregate grading, and other additions that extend the service life of the resulting structure. For more information about UHPC, check out this article and map from FHWA.
