Soil and Rock Laboratory
Laboratory tests are performed to determine the engineering properties of soil and rock within a controlled setting. Testing is in accordance with standard procedures, such as those specified by the American Society for Testing and Materials (ASTM), American Society of State Highway Transportation Officials (AASHTO), Pennsylvania Test Methods (PTM), and Virginia Test Methods (VTM).
Equipment calibration and verification and established data recording and reporting practices are part of our laboratory Quality Management System. Our laboratory accreditation is provided by AASHTO Accreditation Program (AAP).
We perform standard soil testing, chemical analysis of soil and water, and standard rock testing. If there is specialized testing that we are unable to perform in our laboratory or the samples contain hazardous materials, we have an established network of local outside laboratories to meet those demands.
