Initial Evaluation of the WSDOT Quality Assurance Specifications for Asphalt Concrete

S. J. Markey / J. P. Mahoney / R. H. Gietz

The Washington State Department of Transportation (WSDOT) did a trial implementation of a quality assurance (QA) specification for asphalt concrete during the 1989 paving season. To assess the QA specification, data from both non-QA and QA projects built that year were compared. Based on these results, the QA projects were evaluated as having improved quality. Subsequently, the QA specification was fully implemented within WSDOT.
