DEFINING SPECIFICATION LIMITS WITH RESPECT TO TESTING VARIABILITY (WITH DISCUSSION)

There are two general areas of testing that are associated with the production of any product. Testing by the supplier during production, called process control, is used to minimize product variability while improving the overall quality of the product. Testing by the owner for acceptance of the product is used to determine a course of action by the owner. The most common approaches to process control in highway construction compare test results to predetermined upper and lower limits. Regardless of the type of process control or acceptance testing programs that are used, all plans generate test results that are compared to some limiting criteria. The objectives of this program is to: (1) evaluate the change in historical testing variability when a substantially different aggregate source is introduced into the database and (2) investigate the implications of any changes in testing variability on a typical process control and acceptance testing plan.
