Aggregate Inspection Certification

The Michigan Department of Transportation has revised the requirements for Aggregate Inspection Certification. Beginning in 2013, two different levels of aggregate inspection training and certification will be offered, Aggregate Inspection Certification Level One and Aggregate Inspection Certification Level Two. Technicians that are currently Certified for Aggregate Inspection are eligible to enroll in Aggregate Inspection Level Two. Technicians that are NOT currently Certified for Aggregate Inspection are required to complete the Aggregate Inspection Level One training before enrolling in the Aggregate Inspection Level Two training. Technicians inspecting fine aggregates or road gravel are required to complete the Aggregate Level One training. Technicians inspecting concrete aggregates or asphalt aggregates are required to complete Aggregate Level Two training. Please contact our office by phone; 231-591-5826, or by email; [email protected], with any questions about this change in the Aggregate Certification requirements.
