2012 STANDARD SPECIFICATIONS FOR CONSTRUCTION - SECTION 105
Email this Page

Materials Quality Assurance (QA) sampling and testing procedures described in this manual have been developed by Michigan Department of Transportation (MDOT) in accordance with Title 23, of The Code of Federal Regulations, Part 637. Objectives of the program include the design and implementation of sampling and testing procedures to assure that materials are in reasonably close conformity with plans and specifications. The Materials QA program includes acceptance sampling and testing, independent assurance testing, project materials certification, retention of sampling and testing records, verification of test procedures, calibration of testing apparatus and participation in the development and implementation of technical training for personnel involved in materials sampling and testing.


The Materials Quality Assurance Procedures Manual is found at the following link: http://www.michigan.gov/mdot/0,4616,7-151-9622_11044_11367-207980--,00.html
