The Material Quality Assurance Processes Manual is published online by the Office of Materials Technology (OMT) as a centralized location for tasks, procedures and frequencies for the evaluation of material quality. Use this manual along with the Maryland Department of Transportation State Highway Administration (MDOT SHA) Standard and Supplemental Specifications for Construction and Materials , the Book of Standards for Highway and Incidental Structures and other specification sources. The Material Quality Assurance Process Manual does not supersede any official specification but is intended to summarize the Quality Assurance (QA) process by material.

This manual has been updated as noted below under Revision History. MDOT SHA does not print hard copies of the manual for distribution.
