At the same time that state departments of transportation are allowing contractor-performed quality control, they are also concerned about using the contractor-reported data for acceptance and payment purposes. The question is, are we putting the fox in charge of guarding the chickens? To address this concern, a large number of asphalt and concrete projects in Kentucky were examined. The statistical analyses showed that for the most part there is no significant difference between the contractor-performed acceptance data and concomitant highway agency-performed verification data. This is obviously a very encouraging finding that is expected to enhance the level of trust between the contractors and highway agencies.
