This paper presents a number of ways in which a computer can be used to assist in the development of statistically based acceptance plans. These techniques include statistical analysis of preliminary data to determine the appropriate parameters to use in the development of the acceptance plan. Data collected from 13 bituminous airport pavement construction projects were used to develop a proposed acceptance plan for asphaltic concrete density. A computer algorithm was used to calculate the probabilities neceassary to determine the operating characteristics (OC) curves for the plan. Another computer program was used to estimate the integral necessary to determine the expected payment curve associated with a continuous price adjustment schedule. The continuous price adjustment schedule eliminates the problem of having relatively large differences in payment associated with small differences in quality. This situation is encountered frequently in the discrete price adjustment schedules typically used in pavement construction. A computer simulation program used to determine the OC curves for the proposed density acceptance plan is presented. The OC curves from the simulation agree very closely with OC curves that were calculated by theoretical means. The simulation program provides an advantage over the theoretical solution in that it provides OC curves in terms of means and standard deviations that can be related easily to the contractor's process capabilities. The simulation program presented can be used to develop OCs for properties that require either one-sided or two-sided specification limits. (Author)
