This month’s edition of Everyday Asphalt ventures into the quarry to uncover the world of rocks and the Surface Aggregate Classification (SAC) system. Dr. Jon Epps and Richard Izzo join the conversation to explain when, where, how, and why specific aggregates are essential for roadway surfaces—and the challenges that come with it.
We’ll explore geography, geology, aggregate testing, supply and demand, and what it takes to ensure the right rock ends up on the right road. Wondering how many SAC A sources exist in Texas?
