Characterization of pavement texture by use of surface profiles - Part 5: Determination of megatexture (ISO/DIS 13473-5:2024)

ISO 13473-5:2009 specifies procedures for determining the average depth or level of pavement surface megatexture by measuring the profile curve of a surface and calculating megatexture descriptors from this profile. The technique is designed to give meaningful and accurate measurement and description of pavement megatexture characteristics for various purposes.
Since there is an overlap between megatexture and the surrounding ranges, the megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. ISO 13473-5:2009 specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 8608 and EN 13036-5.

Caractérisation de la texture d'un revêtement de chaussée à partir de relevés de profils de la surface - Partie 5: Détermination de la mégatexture (ISO/DIS 13473-5:2024)

L'ISO 13473-5:2009 spécifie des modes opératoires permettant de déterminer la profondeur moyenne ou le niveau de la mégatexture d'une surface de revêtement en mesurant la courbe du profil de cette surface et en calculant les descripteurs de mégatexture de ce profil. La technique a été élaborée pour donner une mesure et une description significatives et précises des caractéristiques de la mégatexture du revêtement pour différentes utilisations.
Du fait du recouvrement entre la mégatexture et les domaines voisins, les descripteurs de la mégatexture présentent inévitablement une certaine corrélation avec les mesures correspondantes de ces autres domaines. L'ISO 13473-5:2009 spécifie des mesurages et des modes opératoires qui sont dans leurs différents aspects aussi compatibles que possible avec ceux de l'ISO 13473-1, de l'ISO 8608 et de l'EN 13036-5.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
