BTE concrete testing labs are certified by CCRL. Its labs are also accredited by the American Association of State Highway and Transportation Officials. AASHTO is a standards setting body which publishes specifications, test protocols, and guidelines that are used in highway design and construction throughout the United States. The association promotes quality and the achievement of excellence in constructions materials testing (CMT). AASHTO18 accreditation is considered the gold standard upon which the entire certification program is based and includes Quality Management Systems, Asphalt Mixture, Soil and Concrete Testing. BTE's ASTM E 329 certification upholds the standards for the accuracy of data, management systems, testing criteria, and code compliance and regulations.
