Aztech’s laboratory focuses on accurate & quality materials testing.

Aztech’s laboratory

Aztech’s laboratory focuses on accurate & quality materials testing. It is accredited by the American Association of Highway and Transportation Officials (AASHTO) for soil, aggregates, concrete, & asphalt.

Consistent and constant review of laboratory procedures and test results is foremost. To assure quality, our materials testing laboratory participates in external audits administered by the Cement and Concrete Reference Laboratory (CCRL) and AASHTO.

Our Field Technicians coordinate closely with our Laboratory Technicians in order to record and log every sample so that meticulous sample management, storage, and testing requirements are provided for every project.

Aztech’s experienced staff is knowledgeable and qualified to perform tests according to the required methods and procedures.

Laboratory test results and computations are reviewed systematically by Aztech staff and by internal checks of computer software. Finally, the Laboratory Manager performs a meticulous review of each test result report prior to Client delivery.

Our state-of-the-art laboratory contains new, calibrated equipment to provide accurate test results. Each piece of equipment has a unique identification number and calibration schedule maintained by the Laboratory Manager for precise, repeatable testing.

Each sample brought to our laboratory is logged in and given a unique identification number for sample management purposes. The sample log describes the project name, project number, name of the supplier, material source, material type, location sampled, date sampled, sampler’s name, date received, test(s) required, and the condition of the sample.
