Abstract
The development of a prototype performance-related specification (PRS) for concrete pavement construction is summarized. The prototype PRS requires that a pavement lot be divided into consistent sublots for the measurement of quality characteristics, which are then used to estimate future performance and life-cycle costs. The difference between the life-cycle costs of the target (as-designed) pavement and the actual (as-constructed) pavement lot is used to determine a rational pay adjustment. Both means and variations of all quality characteristics are directly considered in the pay factor determination. Extensive laboratory testing was conducted to determine material relationships needed in the prototype PRS. A Windows-based computer program, PaveSpec, was developed for use with the specification in simulation and in generating pay adjustments. However, additional work is required to make this a fully practical PRS.
