Abstract
The performance of road and airport wearing courses does not depend only on their bearing capacity. Many of the properties and characteristics of a pavement, such as its friction, drainability, and acoustic absorption, influence its real and perceived economic value. Thus, research is needed to develop reliable contracts and acceptance criteria for wearing courses, taking into account a variety of characteristics. The goal of the study described in this paper was to formalize and validate a model for determining pay adjustments on the basis of traditional and "premium" qualities. A new quality measure and a new and comprehensive algorithm, based on performance-related specifications and life-cycle cost analysis, were formulated and applied to a case study. The algorithm can also be applied to porous asphalt concretes or similar open-graded friction courses. Analyses and validation demonstrate that the proposed algorithm can efficiently solve typical problems that arise in contract administration for which decisions based on objective criteria are needed.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
