The Central Materials Laboratory is responsible for providing statewide support to the construction and maintenance programs. It does this by performing specialized testing on asphalt and asphalt oil, aggregate, soil, and structural materials as well as supporting the Statewide Quality Assurance program.
The Construction Section developed a laboratory certification program to support the Oregon Department of Transportation’s Quality Assurance Program for Construction Materials. To review the Program, please refer to the Manual of Field Test Procedures. To see a complete list of laboratories that are currently certified, please refer to this Certified Laboratories spreadsheet.
Our lab reports are available through FileNet. You may search for a report by lab report number, contract number, data sheet number and more!
A list of all Construction Section Material Labs with addresses are located on the resources page.
