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 Mn/DOT highway construction. It is inserted into project proposals, and is project specific.
Lab Testing & Inspections Rates
Rates Memo: Mn/DOT performs sampling, testing, & inspections for State, County, City, and other governmentally funded transportation projects. Other governmental agencies are required to reimburse Mn/DOT for this work. This is outlined in the Sampling, Testing, & Inspections Memo. (PDF 20KB 1pp).
Current Rates: (Effective January 10, 2013) for sampling, testing, & inspection are outlined in the Laboratory, Field Testing, and Inspection Rates (PDF 27KB 2pp). Former rates through January 9, 2013 (PDF 19KB 2pp).
Mn/DOT's Schedule of Independent Assurance Sampling and Testing Protocol (IAST) 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.
Independent Assurance Inspector Group (IAIG)
Contact the Mn/DOT District Independent Assurance Inspector when project starts to provide the proper servicing of your project.

Approved/Qualified and Certified Products Lists
All materials, equipment and sources that meet Mn/DOT Specifications are categorized by product type or type of application. This area includes all product lists as well as requirements for obtaining product approval. Product Lists
Lab Testing and Inspection
Mn/DOT performs laboratory testing of materials for construction, maintenance, and research. All Mn/DOT labs are certified by AMRL. Mn/DOT also performs Materials Inspection on several types of materials used on construction projects. Materials Lab Testing and Inspection
Each year, the Mn/DOT 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
Materials and Road 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.
