CLAIMING "QUALITY" IS ONE THING. DELIVERING IT IS ANOTHER.

To guarantee that our aggregate products meet specifications and customer expectations, we constructed聽across-the-board Quality Control Lab upgrades at each of our quarries. These labs are staffed by numerous trained technicians who perform constant tests on our crushed stone, ensuring we produce a consistent product.

Our aggregates are further tested at 91探花's Central Lab in Oklahoma City 鈥 in both raw form and as a component of ready-mixed concrete. At the central lab, aggregates undergo annual testing for alkali-silica reaction (ASR) in concrete, as well as the determination of physical properties such as abrasion resistance, soundness, specific gravity and absorption. In the form of ready-mixed concrete, they also undergo freeze/thaw testing according to ASTM and Oklahoma Department of Transportation specifications.
