These lists provide sources of materials that have been qualified by the Maryland Department of Transportation State Highway Administration (MDOT SHA) for use on State projects. This page is a reference for source of supply approval and does not imply that materials can be used on MDOT SHA projects without normal quality assurance testing and procedures.
Each item was submitted, tested and approved. Approval procedures are listed with each material category. Contact MDOT SHA for additional information.
When a product is approved or corrections are made, an updated copy of the qualified list is posted online. Refer to the date at the bottom of the list (PDF) for the last update.
Direct any questions concerning each list to the appropriate product manager. See the related material category Product Qualification Procedure for contact information.
