Comprehensive CMT Services

Field Testing
Our professionals observe and test sub-grade preparation, installation of sub-grade drainage systems, placement and compaction of aggregate base course, placement and compaction of bituminous materials, and concrete materials.

Plant Inspection
We offer plant inspection, including calibration of the plant and testing of stockpiled material prior to the start of production. We monitor material handling procedures, mix proportions, mixing temperatures and mixing time during production, and sample the final mixtures to ensure conformance with project requirements and approved mix designs.

Laboratory Materials Testing
Our laboratory facilities comply with ASTM E329 and ASTM D3740 for agencies engaged in the testing and/or inspection of materials used in construction. In addition, our laboratories participate in the AASHTO Materials Reference Laboratory, and Cement and Concrete Reference Library (CCRL) programs. The NTH concrete laboratory staff is trained in the latest American Society for Testing and Materials (ASTM) and American Concrete Institute (ACI) testing methods.

Certified Technical Staff
More than 85% of our technical personnel are certified by the Michigan Asphalt Paving Association (MAPA), Michigan Concrete Association (MCA), American Concrete Institute (ACI), American Welding Society (AWS), American Society of Nondestructive Testing (ASNT), and other organizations.
