How Is RockAsphalt© Different?

Why It's Better


Everything starts with the unique native rock asphalt we mine in southwest Texas. Simply put, it’s the reason for the industry-leading durability and all-weather performance of our pothole patch.


It might start with our native asphalt but it doesn’t end there. We’ve engineered every part of our design and production process to ensure the performance of our patching material on distressed pavement.


A quality product requires quality people. We’re a family owned and operated business that’s been providing native RockAsphalt© to DOT's and industrial clients for roads and highways since 1895.


We're proud of our legacy but that hasn't stopped us from striving to improve. A commitment to testing, analyzing, and optimizing the long-term performance of our patch informs everything we do.

What Customers Say

PW Manager Jerry Long On How RockAsphalt© Cut Road Complaints In His City By 55%

“A few bags of RockAsphalt turned any truck we had into a “pothole repair vehicle” and that’s what got us through the winter. […] I was skeptical they [the patches] would hold up but most all of them did, even the ones in high-traffic intersections. They [RockAsphalt] changed the way we work. I'd recommend the product to anyone.”
