As indicated below, QT is AASHTO Accredited to perform nearly every type of laboratory material test that would be encountered on a typical heavy civil construction project. Along with testing soils, aggregates, hot mix asphalt concrete (HMA) paving mixtures and Portland cement concrete, the extensive asphalt cement and asphalt rubber binder testing services offered by QT is quite rare among private laboratory testing firms in the United States.
