Concrete's Importance to Infrastructure
What You'll Learn
- Why concrete is far more complex than it appears—and how small mix changes can determine whether infrastructure lasts 10 years or a century
- How climate-specific concrete design could improve durability, especially in freeze-thaw environments
- Why 3D-printed concrete is gaining momentum—and how labor shortages and cost pressures are accelerating its adoption
- What APTA’s new AI guidelines mean for public transit agencies
- How AI-powered tools like Moovit are changing the way riders plan and navigate transit systems
Episode 12 of the Infrastructure Technology features Roads and Bridges Staff Writer Jessica Parks interviewing Dr. Tyler Ley, a structural engineering professor at Oklahoma State University. A self-described “concrete freak”, Ley discusses why concrete matters so deeply to infrastructure, how better concrete design can create structures that last generations and how innovation is transforming the field.
After the interview, Mass Transit magazine Associate Editor Brandon Lewis leads a discussion around new artificial intelligence (AI) guidances released by the American Public Transportation Association for transit agencies in the U.S. The hosts discuss AI’s growing role in customer service, operations, policy, staffing and route optimization. They also analyze Moovit’s new AI-powered transit assistant and debate how AI will continue reshaping infrastructure and transportation industries.
