Slurry surfacing - Test methods - Part 4: Determination of cohesion of the mix
This draft European standard specifies a method for design of slurry mix measuring the minimum cohesion to determine the 'set time' and the "trafficability time" of a slurry surfacing. This European standard applies to slurry surfacing to be used in surface layers excluding airfields pavements.
Dünne Asphaltschicht in Kaltbauweise - Prüfverfahren - Teil 4: Bestimmung der Kohäsion der Mischung
Dieser Europäische Norm-Entwurf legt ein Verfahren zur Zusammensetzung von Schlämme-Mischgut fest, mit dem die Brechzeit und die Verkehrsfreigabezeit einer Schlämme-Schicht durch Messung der Mindest-Kohäsion bestimmt werden. Dieser Europäische Norm-Entwurf gilt für dünne Asphaltschichten in Kaltbauweise, die in Oberflächenschutzschichten verwendet werden; sie gilt nicht für Flugplätze.
Matériaux bitumineux coulés a froid - Méthode d'essai - Partie 4: Détermination de la cohésion du mélange
La présente Norme européenne décrit une méthode d'essai pour déterminer la cohésion minimale d'un matériau bitumineux coulé a froid pour permettre d'en connaître le temps de prise et le délai de remise en circulation.
Cette Norme Européenne s'applique aux matériaux bitumineux coulés a froid utilisés en couche de surface.
NOTE Pour certains mélanges grenus, la précision est faible a cause d'une perte important de granulats, une observation devra etre mentionnée dans le rapport d'essai.
