Concrete’s Importance to Infrastructure

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.  Featured Guest Dr. Tyler Ley - Oklahoma State University Dr. Tyler Ley is a structural engineering professor at Oklahoma State University. A self-described concrete freak, in between teaching concrete instructional engineering at Oklahoma State University and conducting innovate research, Ley is the creator behind his YouTube channel, where he breaks down the world of concrete in a way that's engaging, relatable and fun for thousands of viewers.  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 Inside the Episode Episode Length: 35:47 Timestamps:  1:20 — Roads & Bridges interview  27:45 — Interview takeaways 29:40 — APTA AI guidance Useful Links Dr. Tyler Ley's Youtube Channel OSU College of Engineering, Architecture and Technology APTA AI Guidance Roads & Bridges Mass Transit Send us a topic suggestion!  Don’t forget to subscribe to the ITP and rate and review our podcast!
