The rolling straightedge is a device designed to measure large-scale surface irregularities, thus providing a means for evaluating the riding quality of a pavement. In this paper, it is used as a example to illustrate the derivation of a statistically based specification. A Monte Carlo simulation procedure is used to determine the component of variance attributable to the actual pavement roughness and the manner in which it is sampled. This is combined with the variance associated with the precision of the device to obtain the overall variance of the measurement process. The desired quality levels are selected and appropriate producer's and consumer's risks are chosen to derive the necessary specification acceptance limits for both bituminous and concrete pavement. A table is included that gives the variability associated with several possible sampling plans. Operating characteristic curves are presented that illustrate the capability of the resultant specifications. A discussion of the various ramifications of this method is included to provide assistance to those wishing to apply this general approach to other measurement processes to derive specifications with balanced producer's and consumer's risks.
