Resumen de A method for benefiting pavement quality assurance measures related to roughness condition surveys
Nowadays, profile measurements are widely used either for the evaluation of initial smoothness or for monitoring the roughness of in service pavements. For both cases the adoption of roughness specifications or trigger values is always an issue as they influence the road life-cycle costs. In this paper, consideration is given to some of the available criteria in which roughness indices or methods, such the International Roughness Index (IRI) or the Power Spectral Density (PSD) analysis of a road profile or even the surface tolerance are used for roughness condition survey. The paper briefly describes the development of a method for establishing weighted trigger IRI in terms of roughness acceptance specifications based on some geometrical aspects of pavement surface, which are associated with PSD analysis results and surface tolerance. The related outcomes, which are based on in-situ measurements, benefit quality assurance measures related to pavement condition surveys.
