New Road Surfaces: Logical Bases for Simple Quality-Related Pay Adjustments / Pratico', F.G.. - In: JOURNAL OF CONSTRUCTION ENGINEERING AND MANAGEMENT. - ISSN 0733-9364. - 139:11(2013), pp. 04013020-1-04013020-9.
Abstract:
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. DOI: 10.1061/(ASCE)CO.1943-7862.0000713.
