Quality control and quality assurance in the highway industry is going through a cultural shift. There is a growing trend toward using the contractor data for acceptance and payment purposes. This has led to serious concerns about conflicts of interests. The question remains: are there adequate safeguards in place? To address these concerns, a number of asphalt and concrete QC/QA projects in Kentucky were examined and statistical analyses were conducted. This report presents a summary of findings and recommendations. Generally speaking, the Kentucky experience revealed that the QC/QA system is working well, and the agency’s random inspection data when compared to the contractor reported QC data showed similar trends. However, it is critical for the verification regime to be truly independent.
