As we move the Everyday Asphalt studio and make some exciting updates to the show, we’re taking a stroll down memory lane with one of our most popular episodes: The Science Behind Rocks and Roadways from October 2024.

This fan-favorite edition takes a deep dive into the quarry to explore the Surface Aggregate Classification (SAC) system. Dr. Jon Epps and Richard Izzo join the conversation to break down when, where, how, and why specific aggregates are needed on our roadways, and the unique challenges that come with it.

We cover everything from geography and geology to aggregate testing, supply and demand, and what it really takes to get the right rock on the road. How many SAC A sources are there in Texas? Tune in and find out!
