Over the years, the South Carolina Department of Transportation (SCDOT) has initiated various procedures to improve the Quality Assurance (QA) programs it uses to verify that quality asphalt paving mixtures are used on its projects. The SCDOT QA Program currently consists of the Record Sample, Independent Assurance (known as the Green Tag Program), and Split Sample programs. Because these three programs developed at different times and possibly for different reasons, a study was needed to determine how the three programs mesh together, if there are overlaps or gaps in these programs, and if they are serving the function or functions for which they were intended. The study consisted of a review of the documentation of the existing programs, interviews with the Federal Highway Administration (FHWA) and SCDOT personnel to establish the objectives for each program, a survey of other State Highway Agency Independent Assurance (IA) practices, and an analysis of historical data from each of the programs.
