Summary: Diese Technische Spezifikation beschreibt ein Verfahren für die Bestimmung der Griffigkeit von Fahrbahn-decken durch Messung des Schlupfes in Längsrichtung (en: Longitudinal Friction Coefficient; LFCS). Diese Technische Spezifikation behandelt den Betrieb des Straßenzustandserfassungsgeräts von Arsenal Research (en: Road Surface Tester of Arsenal Research; RoadSTAR). Das „RoadSTAR“-Verfahren liefert ein Maß für die Griffigkeitseigenschaften einer gebundenen Fahrbahn-decke durch Messung der Reibungszahl in Längsrichtung mit Hilfe eines kontinuierlich messenden Messfahr¬zeugs mit gebremstem Rad und festgelegtem Schlupf. Das „RoadSTAR“-Verfahren ermöglicht die Messung der Griffigkeit von Fahrbahndecken mit Hilfe des modifi-zierten Stuttgarter Reibungsmessers. Das RoadSTAR-Gerät verwendet eine Messung, die die stationäre Reibung an einem gebremsten Messrad bei einem Schlupfverhältnis von 82 % (für Normbedingungen), 37,5 %, 50 % und 75 % (für Vergleichsmessungen) mit blockiertem Rad oder unter ABS-Bremsbedingungen (für Forschungsmessungen) darstellt. Das Messrad wird unter geregelten Last- und Geschwindigkeits-bedingungen über eine zuvor angenässte Fahrbahndecke gezogen, wobei der Messreifen parallel zur Bewegungsrichtung und rechtwinklig zur Fahrbahn steht. ANMERKUNG Es werden drei unterschiedliche Schlupfverhältnisse beibehalten, um dieselbe Schlupfgeschwindigkeit für die drei verschiedenen nominellen Messgeschwindigkeiten von 40 km/h, 60 km/h und 80 km/h für Vergleichsmessun¬gen zu verwenden. Die allen gemeinsame Schlupfgeschwindigkeit wird gleichbleibend mit 30 km/h angesetzt: - bei einer Messgeschwindigkeit von 40 km/h sollte ein Schlupfverhältnis von 75 % angewendet werden; - bei einer Messgeschwindigkeit von 60 km/h sollte ein Schlupfverhältnis von 50 % angewendet werden; - bei einer Messgeschwindigkeit von 80 km/h sollte ein Schlupfverhältnis von 37,5 % angewendet werden. Für die Prüfungen sollte ein den allgemeinen Kennwerten des RoadSTAR-Geräts (...)

This Technical Specification describes a method for determining the skid resistance of a paved surface by measurement of the longitudinal friction coefficient LFCS. This Technical Specification covers the operation of the Road Surface Tester of arsenal research (RoadSTAR). The method "RoadSTAR” provides a measure of the skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a continuous reading car sized braked wheel fixed slip device. The method "RoadSTAR” provides skid resistance measurements of pavements by using the modified Stuttgart skiddometer (Stuttgarter Reibungsmesser). RoadSTAR utilizes a measurement representing the steady-state friction on a braked test wheel at a slip ratio of 82 % (for standard conditions), 37,5 %, 50 %, 75 % (for comparison measurements), with locked wheel or under ABS-braking conditions (for research measurements). The test wheel is dragged over a pre wetted pavement surface under controlled load and speed conditions while the test tyre is parallel to the direction of motion and perpendicular to the pavement. NOTE Three different slip ratios are retained in order to use the same slip speed for the three different nominal testing speeds of 40 km/h, 60 km/h and 80 km/h for comparison measurements. The common slip speed is chosen equal to 30 km/h: - for a testing speed of 40 km/h a slip ratio of 75 % should be applied; - for a testing speed of 60 km/h a slip ratio of 50 % should be applied; - for a testing speed of 80 km/h a slip ratio of 37,5 % should be applied. A machine conforming to the general characteristics of the RoadSTAR and the specific provisions of this Technical Specification should be used for the tests. In addition to friction measurements, to estimate the macro texture of the pavement surface, a laser system is used. This system is placed in front of the test wheel in order to be able to measure macrotexture (mean profile depth – MDP) on the dry surface and o

La présente Spécification technique décrit une méthode permettant de déterminer l’adhérence d’une surface de chaussée revêtue par mesure du coefficient de frottement longitudinal (CFL). La présente Spécification technique couvre le fonctionnement du RoadSTAR (Road Surface Tester of Arsenal Research). La méthode "RoadSTAR" permet de déterminer les propriétés d’adhérence d’une couche de roulement en mesurant le coefficient de frottement longitudinal à l’aide d’un appareil de mesure en continu associé à un véhicule, et dont le taux de glissement de la roue freinée est constant. La méthode "RoadSTAR" permet de mesurer l’adhérence de la chaussée à l’aide d’un appareil SRM (Stuttgarter Reibungsmesser) modifié. RoadSTAR utilise un mesurage représentant le frottement permanent exercée sur une roue d’essai freinée selon un taux de glissement de 82 % (conditions normalisées), 37,5 %, 50 %, 75 % (mesurages de comparaison), dans des conditions de freinage roue bloquée ou ABS (mesurages de recherche). La roue d’essai est traînée sur une chaussée préalablement mouillée, selon des conditions de charge et de vitesse contrôlées, le pneumatique d’essai étant parallèle à la direction du mouvement et perpendiculaire à la chaussée. NOTE Trois taux de glissement différents sont retenus afin d’utiliser la même vitesse de glissement pour les trois vitesses d’essai nominales de 40 km/h, 60 km/h et 80 km/h pour les mesurages de comparaison. Avec une vitesse de glissement commune de 30 km/h : - pour une vitesse d’essai de 40 km/h, il est nécessaire d’appliquer un taux de glissement de 75 % ; - pour une vitesse d’essai de 60 km/h, il est nécessaire d’appliquer un taux de glissement de 50 % ; - pour une vitesse d’essai de 80 km/h, il est nécessaire d’appliquer un taux de glissement de 37,5 %. Pour les essais, il convient d’utiliser une machine conforme aux caractéristiques générales du RoadSTAR et aux dispositions particulières de la présente Spécification technique. (...)
