AASHTO re:source Q & A Podcast

This episode explores the development and significance of the new AASHTO R 119 standard, officially titled “Standard Practice for Grinding the Ends of Cylindrical Concrete Specimens.”

Brian shares his firsthand experience in creating this standard, highlighting the collaborative efforts with various state DOTs and the importance of standardizing concrete practices. Listeners will learn why AASHTO R 119 is crucial for those working with ultra-high-performance concrete (UHPC) and how it addresses the limitations of traditional capping methods.

The episode also looks at the broader implications of AASHTO R 119, including its potential integration into other key standards like AASHTO T 24, ASTM C31, and ASTM C39. We also discuss how AASHTO R 119 moved from a provisional to a full standard and the ongoing efforts to promote its adoption across the industry.
