materials testing
EMC’s Palmer laboratory is accredited by the AASHTO Accreditation Program (AAP). The accreditation is limited to the laboratory and the standards for which the laboratory is accredited. 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 biannual onsite inspections from the AASHTO re:source 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.
