Asphalt - Prüfverfahren - Teil 41: Widerstand gegen chemische Auftaumittel

Dieses Dokument legt ein Prüfverfahren zur Bestimmung des Widerstands von Asphalt gegen chemische Auftaumittel fest. Das Verfahren bestimmt die Oberflächenzugfestigkeit eines Asphaltprobekörpers nach der Lagerung in chemischem Auftaumittel.
Dieses Dokument wird hauptsächlich zur Prüfung von Asphalt angewendet, der auf Flugplätzen eingebaut werden soll; es kann jedoch auch auf Asphalt angewendet werden, der zum Einbau auf Straßen oder anderen befestigten Flächen bestimmt ist.

Mélanges bitumineux - Méthodes - Partie 41 : Résistance aux agents déverglaçants

Le présent document décrit une méthode d’essai pour la détermination de la résistance des matériaux bitumineux aux agents déverglaçants tels que les solutions d’acétate et de formiate. La procédure détermine la résistance à la traction superficielle d’une éprouvette d’asphalte qui a été entreposée dans un agent déverglaçant.
Ce document sert principalement à la réalisation d’un essai sur de l’asphalte à couler sur les terrains d’aviation, mais il peut être utilisé pour l’asphalte destiné aux routes et autres chaussées.

1 Scope

This document specifies a test method to determine the resistance of bituminous materials to de-icing

fluids such as solutions of acetate and formate. The procedure determines the surface tensile strength of

a specimen of asphalt which has been stored in de-icing fluid.

This document is primarily used as a test on asphalt to be laid on airfields, but it can be used for asphalt

to be laid on roads or other paved areas.

3.1
surface tensile strength

tensile stress at maximum force when testing the surface tensile strength according to this test method

4 Principle

Testing is performed on a sawn cylindrical specimen of asphalt on which a well-defined test surface has

been drilled out in the bituminous mixture to a depth of about 5 mm. Four specimens are stored and four

are not stored in a de-icing fluid. A steel plate is bonded to the test surface of each specimen in turn.

During testing, the plate is pulled off with a tensile force increasing at a rate of 200 N/s, the force being

applied perpendicular to the test specimen surface. The tensile force at failure load and the mode of

failure are recorded. The results are compared with those for specimens which have not been stored in

de-icing fluid.
