Road and airfield surface characteristics - Part 14: Procedure for determining the skid resistance of a pavement surface using a device with longitudinal controlled slip (LFCN): ViaFriction (Road Analyser and Recorder of ViaTech AS)
N CEN/TS 15901-14
Annotation
Diese Technische Spezifikation beschreibt ein Verfahren fur die Bestimmung der Griffigkeit von nassen Fahrbahndecken durch Messung des Reibungskoeffizienten in Langsrichtung, LFCN. Das beschriebene Verfahren wird ebenfalls dazu verwendet, die Griffigkeit auf einer vereisten oder verschneiten Fahrbahndecke zu bestimmen.
Das Verfahren liefert Messungen fur den Reibungskoeffizienten einer gebundenen Oberflache durch einen elektrisch gebremsten Messreifen.
Das ViaFriction-Messgerat kann auf die folgenden Weisen angewendet werden:
- Fester Schlupf: das Schlupfverhaltnis ist festgelegt. Das Schlupfverhaltnis kann auf einen Wert zwischen 1 % und 75 % eingestellt werden.
- Feste Schlupfgeschwindigkeit: die Schlupfgeschwindigkeit ist festgelegt. Die Schlupfgeschwindigkeit muss niedriger sein als die Fahrgeschwindigkeit.
- Veranderlicher Schlupf: der Messreifen wird von einem Schlupfverhaltnis von 0 % auf 75 % abgebremst und zeichnet F30, F60 sowie die Kurve von Schlupfverhaltnis/Reibung auf.
Der Messreifen wird mit vertikaler Kraft und geregelter Geschwindigkeit uber eine zuvor angenasste Fahrbahndecke gezogen, wobei er parallel zur Bewegungsrichtung und rechtwinklig zur Fahrbahn lauft. Griffigkeitsmessungen auf winterlichen Stra?en erfordern kein Annassen der Fahrbahndecke.
Zur Bestimmung der Makrotextur der Fahrbahndecke kann zusatzlich ein Lasersystem verwendet werden. Dieses System wird vor dem Schleppfahrzeug angeordnet, um die Messung der Makrotextur (mittlere Profiltiefe, MPD) auf der trockenen Fahrbahn und auf der fur die Griffigkeitsmessungen verwendeten Messstrecke zu ermoglichen. Das Normverfahren fur diese Messung und das dafur zu verwendende Messgerat sind in EN ISO 13473-1 beschrieben.
