In this episode of The Civil Engineering Podcast, host James Taylor interviews John Sheerin, Director of End-of-Life Tire Programs at the US Tire Manufacturers Association, about the use of scrap tires in civil engineering projects. Sheerin discusses the evolution of end-of-life tire management, the engineering applications of Tire Derived Aggregate (TDA), and key insights from USTMA's State of Knowledge Report. He highlights the sustainability and engineering benefits of TDA, including its lightweight properties, superior drainage, and cost-effectiveness, while addressing environmental concerns and regulatory challenges. The conversation also explores best practices for TDA use in embankments, retaining walls, road repairs, and stormwater management, emphasizing the importance of education and innovation in expanding the adoption of recycled materials in infrastructure projects.
