Our laboratory is accredited by the American Association of State and Highway Transportation Officials (AASHTO).  Obtaining and maintaining an AASHTO accreditation requires us to retain qualified staff, participate in proficiency sample programs, maintain calibration and update training records. Accreditation also requires successful completion of annual onsite inspections from the AASHTO Materials Reference Laboratory (AMRL) and Cement and Concrete Reference Laboratory (CCRL). Our laboratory is also validated by the U.S. Army Corps of Engineers. We provide specialized and basic testing of soils, concrete, and asphalt.  The laboratory and field testing is performed in accordance with each project’s specified test methods.
