Road and airfield surface characteristics - Part 13: Procedure for determining the skid resistance of a pavement surface by measurement of a sideway force coefficient (SFCO): the Odoliograph

This Technical Specification describes a method for determining the wet-road skid resistance of a surface by measurement of a sideway force coefficient SFCO. The method provides a measure of the wet-road skid resistance properties of a bound surface by measurement of sideway-force coefficient at a controlled speed. The method has been developed for use on roads but is also applicable to other paved areas such as airport runways.
This Technical Specification covers the operation of the Odoliograph. This is a device developed by the Belgian Road Research Centre that uses the side-force principle to make routine, expertise and research measurements of skid resistance continuously on long lengths of road.
A machine conforming to the general characteristics of the Odoliograph designed by the Belgian Road Research Centre and the specific provisions of this document may also be used for the tests.
The skid resistance of a pavement is determined by friction measurements and measurements of pavement texture. Where measurement of pavement texture is required the standard for this measurement and the device is described in EN ISO 13473 1.

Oberflächeneigenschaften von Straßen und Flugplätzen - Teil 13: Verfahren zur Bestimmung der Griffigkeit von Fahrbahndecken durch Messung des Seitenreibungsbeiwerts (SFCS): das Odoliograph-Messgerät

Diese Technische Spezifikation beschreibt ein Verfahren für die Bestimmung der Nassgriffigkeit von
Fahrbahndecken durch Messung des Seitenreibungsbeiwertes SFCS. Das Verfahren liefert ein Maß für die
Nassgriffigkeitseigenschaften einer gebundenen Oberfläche durch Messung des Seitenreibungsbeiwertes bei
geregelter Geschwindigkeit. Das Verfahren wurde für die Anwendung auf Straßen entwickelt, es lässt sich
aber auch auf anderen befestigten Flächen, wie z. B. Start- und Landebahnen auf Flugplätzen, anwenden.
Diese Technische Spezifikation behandelt den Betrieb des Odoliograph-Messgeräts. Dabei handelt es sich
um ein Messgerät, das vom belgischen Road Research Centre entwickelt wurde, und bei dem zur
Durchführung von kontinuierlichen Routine-, Gutachten- und Forschungsmessungen der Griffigkeit auf langen
Straßenabschnitten das Seitenkraftprinzip angewendet wird.
Für diese Prüfungen darf auch ein Messgerät verwendet werden, das den allgemeinen Merkmalen des vom
belgischen Road Research Centre entwickelten Odoliograph-Messgeräts und den speziellen Vorgaben dieses
Dokuments entspricht.
Die Griffigkeit einer Fahrbahn wird mit Hilfe von Reibungsmessungen und Messungen der Fahrbahntextur
ermittelt. Das Normverfahren für die Messung der Fahrbahntextur, falls diese erforderlich ist, und das dafür zu
verwendende Messgerät sind in EN ISO 13473-1 beschrieben.

Caractéristiques de surface des routes et des aéroports - Partie 13: Mode opératoire de détermination de l'adhérence de la surface d'un revêtement de chaussée par mesurage d'un coefficient de frottement transversal (CFTO): l'odoliographe

La présente Spécification technique décrit une méthode permettant de déterminer l'adhérence d'une chaussée
mouillée par mesure du coefficient de frottement transversal (CFTO). La méthode permet de mesurer les propriétés
d'adhérence sur chaussée mouillée d'une couche de roulement, par mesure du coefficient de frottement transversal à
vitesse contrôlée. La méthode a été développée en vue d'une utilisation sur des routes, mais s'applique également
aux autres surfaces revêtues (les pistes d'aéroport, par exemple).
La présente Spécification technique couvre l'utilisation de l'odoliographe. Il s'agit d'un appareil développé par le
Centre de Recherches Routières Belge qui utilise le principe de la force transversale pour procéder à des mesures de
routine, d'expertise et de recherche, en continu, de l'adhérence sur de longues sections routières.
Un appareil conçu par le Centre de Recherches Routières Belge, conforme aux caractéristiques générales de
l'odoliographe et aux dispositions particulières du présent document, peut également être utilisé pour les essais.
L'adhérence d'une chaussée est déterminée par des mesures du frottement et de la texture de la chaussée. Si une
mesure de la texture de la chaussée est requise, le principe et l'appareil de mesure sont décrits dans la norme
EN ISO 13473-1.

Značilnosti cestnih in letaliških površin - 13. del: Postopek določanja torne sposobnosti vozne površine z določanjem koeficienta bočne sile (SFCO): Odoliograf

Ta dokument opisuje metodo določanja torne sposobnosti površine mokre ceste z določanjem koeficienta bočne sile SFCF. Ta metoda določa merilo lastnosti torne sposobnosti omejene površine mokre ceste z določanjem koeficienta bočne sile pri nadzorovani hitrosti. Ta metoda je bila razvita za uporabo na cestah, vendar se uporablja tudi za druga vozne površine, kot so letališke vzletne steze.
Ta dokument zajema delovanje odoliografa. To je naprava, ki jo je razvil Belgian Road Research Centre (belgijski center za raziskovanje cest), ki uporablja načelo stranske sile za neprekinjeno izvajanje rutinskih, strokovnih in raziskovalnih meritev torne sposobnosti na dolgih dolžinah ceste.
Za preskuse se lahko uporabi tudi stroj, ki ustreza splošnim značilnostim odoliografa, razvitega na Belgian Road Research Centre, in posebnim določbam tega dokumenta.
Torno sposobnost površine določajo meritve trenja in meritve teksture površine. Kjer se zahteva merjenje teksture površine, je standard tega merjenja in naprave opisan v EN ISO 13473-1.

3 Recommended uses
This method provides a means for the evaluation of the skid resistance of a road surfacing. It is suitable for
use for the following situations:

 for routine determination of the skid resistance of the surface of a road in service;
 research.
4 Terms and definitions
For the purposes of this document, the following terms and definitions apply
4.1
friction
resistance to relative motion between two bodies in contact
NOTE The frictional force is the force which acts tangentially in the contact area
4.2
skid resistance
characterisation of the friction of a road surface when measured in accordance with a standardised method
4.3
wet road skid resistance
property of a trafficked surface that limits relative movement between the surface and the part of a vehicle tyre
in contact with the surface, when lubricated with a film of water
NOTE Factors that contribute to skid resistance include the tyre pressure, contact area, tread pattern, and rubber
composition; the alignment, texture, surface contamination, and characteristics of the road surface; the vehicle speed; and
the weather conditions.
The skid resistance of a road surface in Europe varies seasonally. Generally, wet skid resistance is higher in winter as a
result of the effects of wet detritus and the effects of frost and wear by tyres on microtexture and macrotexture. Wet skid
resistance is lower in summer as a result of dry polishing by tyres in the presence of fine detritus.
The change in skid resistance of a surface in service is affected by the volume of traffic and the composition of the traffic,
i.e. cars, buses, commercial vehicles of different sizes, as the tyres of these vehicles polish and/or wear away the
surfacing material in different ways. The geometry of the road will affect the change in skid resistance. Generally, tyres
polish less on straight roads than on bends.
Where the surface contains aggregate with a coating of binder, e.g. bitumen, resin or Portland cement, the skid resistance
will change as the coating is worn away by tyres.
4.4
bound surface
top layer or surface course of a road with the aggregates secured permanently in place
NOTE Aggregates are commonly secured in place by bitumen or Portland cement.
4.5
operating speed
speed at which the device traverses the test surface
4.6
contact area
overall area of the road surface instantaneously in contact with a tyre
NOTE This term describes the overall area generally covered by the tyre. Due to the effects of surface texture or any
tyre tread pattern, not all of the tyre or road surface in the contact area may be in contact at a
