Road and airfield surface characteristics - Test methods - Part 8: Determination of transverse unevenness and crossfall indices
This document specifies the mathematical processing of digitized transverse profile measurements to produce indices in the transverse direction for unevenness, other defects and crossfall. The document describes the calculation methods of the indices such as irregularities (1) rut depth, (2) ridge height, (3) water depth and area, crossfall and how to evaluate and report the indices. It also describes possibilities to do further analysis to examine defects and problems on the road that can be seen in the transverse profile. The latter is described in Annex E, Other transverse indices (edge deformation/edge slump, crossfall line, rut area and width and the distance between the rut bottoms).
The quantified evenness indices derived from this document are useful support for quality control of newly laid pavement surfaces, especially with respect to the evidence of irregularities due to improper laying and/or compacting actions. It is also useful for evaluating the condition of pavements in service as part of routine condition monitoring programs, and finally as indices to be used for maintenance planning of resurfacing activities on pavements in use. The derived indices are portable in the sense that they can be obtained from transverse profiles measured with any suitable instrument.
All indices described in this document are related to the actual lane and direction of the road at which the measurement is done.
Oberflächeneigenschaften von Straßen und Flugplätzen - Prüfverfahren - Teil 8: Bestimmung von Querunebenheit und Querneigung
Dieses Dokument legt die mathematische Verarbeitung digitalisierter Querprofilmessungen zur Berechnung von Indizes für Querunebenheit, sonstige Mängel in Querrichtung und Querneigung fest. Dieses Dokument beschreibt die Berechnungsverfahren für die Indizes wie z. B. die Unregelmäßigkeiten (1) Spurrinnentiefe, (2) Grathöhe, (3) Wassertiefe und fläche, Querneigung, und wie die Indizes auszuwerten und aufzuzeichnen sind. Es beschreibt auch die Möglichkeiten zur Durchführung weiterer Analysen zur Untersuchung von Mängeln und Problemen der Straßenoberfläche, die im Querprofil zu erkennen sind. Letztere werden in Anhang E „Sonstige Querindizes“ (Kantenverformung/Kantenabsenkung, Querneigungsverlauf, Spurrinnenfläche und breite und Abstand zwischen Spurrinnensohlen) beschrieben.
Die aus diesem Dokument abgeleiteten quantifizierten Ebenheitsindizes sind eine nützliche Unterstützung bei der Qualitätskontrolle der Oberflächen von neu verlegten Fahrbahnbelägen, insbesondere hinsichtlich des Nachweises von Unregelmäßigkeiten infolge unsachgemäßer Verlege- und/oder Verdichtungsarbeiten; Sie sind auch nützlich für die Bewertung des Zustands von befahrenen Fahrbahnbelägen als Teil von regelmäßig durchgeführten Programmen zur Zustandsüberwachung und schließlich als Indizes zur Verwendung bei der Instandhaltungsplanung für Oberflächenerneuerungsarbeiten von befahrenen Fahrbahnbelägen. Die abgeleiteten Indizes sind übertragbar in dem Sinne, dass sie aus Querprofilen erhalten werden können, die mit einem beliebigen geeigneten Gerät gemessen wurden.
Alle in diesem Dokument beschriebenen Indizes beziehen sich auf den konkreten Fahrstreifen und die Fahrtrichtung, für die die Messung tatsächlich durchgeführt wurde.
Caractéristiques de surface des routes et aérodromes - Méthodes d'essais - Partie 8 : Détermination des indices d'uni transversal et de dévers
Le présent document spécifie le traitement mathématique des mesurages numérisés de profils transversaux afin de produire des indices dans la direction transversale pour les défauts d'uni, les autres défauts et les dévers. Le document décrit les méthodes de calcul des indices tels que les défauts (1) la profondeur d'ornière, (2) la hauteur de bourrelet, (3) la hauteur et la surface de l'eau, le dévers, ainsi que la manière d’évaluer et de communiquer les indices. Il décrit également comment réaliser une analyse plus approfondie pour examiner les défauts et les problèmes de la route qui peuvent être constatés sur le profil transversal. Ce dernier est décrit à l'Annexe E, « Autres indices transversaux » (déformation/affaissement de la rive, ligne de dévers, surface et largeur d'ornière et distance entre les fonds d'ornière).
Les indices d'uni quantifiés obtenus à partir du présent document sont utiles pour assurer le contrôle de la qualité des chaussées nouvellement mises en œuvre, notamment en ce qui concerne la détection de défauts dus à une mise en œuvre et/ou à un compactage inapproprié. Ils sont également utiles pour évaluer l'état des chaussées en service dans le cadre des programmes de surveillance de routine et, enfin, en tant qu'indices à utiliser pour la planification de l'entretien des travaux de réfection des chaussées en service. Les indices obtenus sont portables dans la mesure où ils peuvent être obtenus à partir de profils transversaux mesurés à l'aide de tout instrument approprié.
Tous les indices décrits dans le présent document sont liés à la voie et à la direction effectives de la route sur laquelle le mesurage est effectué.

Introduction
Road surface unevenness and crossfall affects safety, ride comfort, environmental impact, and the
technical performance of roads. When a road is in use the surface will be deformed and worn due to the
traffic load. Contributing causes of surface degradation are the time in use, the traffic load,
weather/climate conditions, geological conditions, used materials as well as the strength of the road
construction. To simplify quan
