17th Annual TERRA Pavement Conference
The presentations and other information are currently available online.
Schedule of Materials Control
The Schedule of Materials Control outlines the minimum sampling and testing rates required for most materials used in MnDOT highway construction. It is inserted into project proposals, and is project specific.
Lab Testing & Inspections Rates
Rates Memo: MnDOT performs sampling, testing, & inspections for State, County, City, and other governmentally funded transportation projects. Other governmental agencies are required to reimburse MnDOT for this work. This is outlined in the Sampling, Testing, & Inspections Memo. (PDF 31KB).
Current Rates: (Effective May 1, 2013) for sampling, testing, & inspection are outlined in the Laboratory, Field Testing, and Inspection Rates (PDF 19KB).
Former rates through April 30, 2013 (PDF 93KB).
Former rates through January 9, 2013 (PDF 27KB).
MnDOT's Schedule of Independent Assurance Sampling and Testing Protocol is used by Independent Assurance Personnel on all Federal Aid Construction Projects. The Independent Assurance Program provides a check on testing equipment and procedures for construction projects.

Lab Testing and Inspection
MnDOT performs laboratory testing of materials for construction, maintenance, and research. All MnDOT labs are certified by AMRL. MnDOT also performs Materials Inspection on several types of materials used on construction projects. Materials Testing and Inspection
Each year, the MnDOT Office of Materials performs a complete review of approximately 20 projects throughout the state and checks them for compliance of materials testing requirements and completion of all proper paperwork. Materials Certification Program
MnRoad Research advances the state of the practice of pavement design, construction and maintenance by conducting and participating in pavement and materials research projects, implementation of research results, and supporting practitioners. MnROAD is a unique cold region pavement research test track that is part of the Road Research program.
