Pavement construction pay adjustment schedules have generally been based on a somewhat arbitrary selection of "acceptability limits" with the adjusted pay based on a concept of the percentage of construction within these limits. In this paper an alternate approach applied to asphalt paving is presented and demonstrated. Acceptability limits are selected to represent the capabilities of normal, good contractors. To assure this, the limits are established through an analysis of actual construction test data. For this study, these data include more than 2,300 field density and 2,300 field extraction tests conducted on random samples from past construction projects. The pay adjustments for work outside the identified acceptability limits are then set on the basis of the anticipated relative effect of such deviations on pavement service life. This relative life effect was determined by a quasi-theoretical analysis of laboratory data in which the effects of variations in mixture composition and density were studied. The framework around which the schedule is developed is called the value concept. This concept serves as a rational basis for the establishment of pavement construction pay schedules. As such, it provides a means for considering both the average and the variability (standard deviation or range) of construction test results and provides a mechanism for setting pay adjustments that reflect the impact of construction variability on expected pavement life.
