American Association of State Highway and Transportation Officials (AASHTO) Accreditation

The AASHTO Accreditation Program (AAP) recognizes the competency of GeoTesting Express’ laboratories in construction materials testing. The AAP utilizes laboratory assessment (on-site audits) and proficiency sample services provided by the AASHTO Materials Reference Laboratory (AMRL) and the Cement and Concrete Reference Laboratory (CCRL) for accreditation. GTX’s laboratories are audited once every two years and participate in the proficiency testing program twice per year to ensure compliance with appropriate quality and procedural requirements.

Geosynthetics Accreditation Institute – Laboratory Accreditation Program (GAI-LAP)

The GAI-LAP program ensures that GTX is capable of properly rendering the tests that we are contracted to perform. GTX’s equipment, documentation and testing protocols are evaluated for adherence to standardized test methods. Our lab is audited once every five years and is enrolled in a yearly proficiency test program to ensure compliance with requirements.
