Asphalt Testing Solutions & Engineering (ATS) is pleased to announce it is officially a United States Army Corps of Engineers (USACE) Validated Laboratory for construction material testing! This means ATS is equipped, staffed and qualified to perform asphalt materials testing for the USACE, just as it is for asphalt contractors. ATS is an accredited asphalt lab, and the USACE certification states that ATS “has demonstrated, by abbreviated audit of its AASHTO accreditation, or by inspection of required records, equipment, procedures, facilities and/or final reports, its proficiency to perform testing of construction materials, as established by the quality standards of AASHTO R18 guidance and the requirements of the applicable ASTM standards.
