Statistically based quality assurance specifications, such as the restricted performance bituminous specification of the Pennsylvania Department of Transportation, provide a clear delineation between the acceptance responsibilities and the process control responsibilities of the highway agency and the contractor or material supplier. They also usually require that a process control plan be submitted for approval before the commencement of work. Because the available technical literature has favored the acceptance phase, there is currently little guidance available to these parties when they prepare such a plan. The need for such guidance is illustrated by presenting the two extreme approaches that may be taken to meet the requirements of the Pennsylvania Department of Transportation. The first case illustrates the "ideal" process control plan that can be developed if a literal interpretation of the specification is made. This plan clearly requires excessive documentation. It is contrasted with the process control plans currently being submitted to the Pennsylvania Department of Transportation, which do not provide enough detail to allow a determination of adequacy. A need is thus indicated for the industry to develop technical information that provides guidance in the development of plans that are somewhere between these extremes. /Authors/
