Quality Control and Quality Assurance of Hot Mix Asphalt Construction in Delaware

This report presents a study where the objective is the development of an appropriate statistical acceptance procedure for the Delaware Department of Transportation (DELDOT). DELDOT's modification of its specifications for the acceptance of Hot Mix Asphalt (HMA) in order to incorporate quality assurance concepts lead to requirements such as the emphasis laid on the hot mix asphalt (HMA) producer in terms of quality control activities such as performing component material tests, tracking test results on control charts and following the plan developed by DELDOT. The incorporation of new statistically based acceptance specifications used new criteria for acceptance rather than the previous methods of minimum test result requirements for numerous criteria. After the statistical acceptance procedure was reviewed and used for quantifying and evaluating the DELDOT's statistical plan, a comparative analysis between the developed procedure and the Federal Aviation Administration (FAA) and Federal Highway Administration (FHWA) procedure was done for achieving the objective and providing recommendations and new composite pay factors were developed.
