Bitumen and bituminous binders - Determination of the resistance to hardening under the influence of heat and air - Part 2: TFOT Method.

This European Standard describes a method for measuring the combined effects of heat and air on a film of bitumen or bituminous binder, simulating the hardening that a bituminous binder undergoes during mixing in an asphalt mixing plant.
The method is referred to as TFOT, i.e. Thin Film Oven Test.
WARNING — Use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
If there is a likelihood of volatile components being present in a binder, this procedure should not be used. It should not be used for cutback bitumen or bituminous emulsions before these products have been stabilised, e.g. in accordance with EN 14895.

Bitumes et liants bitumineux - Détermination de la résistance au durcissement sous l'effet de la chaleur et de l'air - Partie 2 : Méthode TFOT

La présente Norme européenne prescrit une méthode qui permet de mesurer les effets combinés de la chaleur et de l'air sur un film mince de bitume ou de liant bitumineux. Elle simule le durcissement que subit un liant bitumineux au cours du malaxage dans une centrale d'enrobage.
L'essai est désigné par TFOT ce qui signifie : Thin Film Oven Test.L'essai est indiqué par TFOT, ce qui signifie: Thin Film Oven Test. Il simule le vieillissement que subit un liant bitumineux au cours du malaxage dans une centrale d'enrobage.
AVERTISSEMENT - L'utilisation de la présente Norme européenne peut impliquer l'intervention de produits, d'opérations et d'équipements à caractère dangereux. La présente Norme européenne n'est pas censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
Si la présence de composés volatils dans le liant est probable, le présent mode opératoire ne doit pas être utilisé. Il peut être utilisé pour les bitumes fluidifiés ou les émulsions avant la stabilisation de ces produits.
