Final Report Abstract
In this study, the researchers evaluated the effectiveness of quality control/quality assurance (QC/QA) specifications in decreasing hot mix asphalt (HMA) variability. A questionnaire was written to gather general information about the QC/QA specification programs that are being used in the United States, and an evaluation of the effectiveness of the QC/QA specification being used by the Wyoming Department of Transportation (WYDOT) in decreasing HMA variability was conducted as a case study.
