Kirkpatrick tests aggregates and concrete once a week from each plant. They also check the batching accuracies of each plant weekly. On jobs for the Alabama Department of Transportation, testing of materials is increased to meet stringent ALDOT requirements. Kirkpatrick also routinely tests ready mix going to projects by verifying the plastics and strength of the concrete.
Kirkpatrick's testing lab is ALDOT Certified. Because Kirkpatrick is ALDOT Certified, they maintain an ACI 214 Statistical Analysis on mix designs. That allows them to submit mixes directly to the customer without having commercial laboratory verification.
