Materials
The Materials Division supports DDOT’s safe and efficient transportation system initiative by evaluating and verifying highway construction materials for compliance with its Standard Spec. and AASHTO/ASTM requirements. The District materials team implements the quality assurance/quality control program through material sampling, testing and inspection by following the Standard Operating Procedure, which from time to time is updated and approved by the Federal Highway.
