Abstract

Quality control of Superpave hot mix asphalt has profound consequences for both the West Virginia Department of Highways (WVDOH) and the constructor who has placed the asphalt. The quality control procedure includes taking samples from the job site, and performing various tests so that certain volumetric parameters can be evaluated against a standard set of tolerances. WVDOH currently uses a statistically based quality control - quality assurance method, QC/QA.;The current QC/QA requirements used by the WVDOH for Superpave projects have not been statistically evaluated to establish the risk to the agency and constructor for either accepting an unsatisfactory material or rejecting a satisfactory material respectively.;The objective of this research was to evaluate risk levels associated with the current methods of QC/QA used by the WVDOH for Superpave construction projects. Risk was defined as the probability of the WVDOH accepting a substandard product or rejecting an acceptable product.
