Bitumen and bituminous binders - Determination of the resistance to hardening under the influence of heat and air - Part 1: RTFOT method

This European Standard specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder simulating the hardening that a bituminous binder undergoes during mixing in an asphalt mixing plant.
The method described is not applicable to some modified binders or to those where the viscosity is too high to provide a moving film. The sample may creep out of the glass container and flow on the heating elements of the oven during testing.
The method is referred to as RTFOT, i.e. Rolling 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.

Bitumen und bitumenhaltige Bindemittel - Bestimmung der Beständigkeit gegen Verhärtung unter Einfluss von Wärme und Luft - Teil 1: RTFOT-Verfahren

Bitumes et liants bitumineux - Détermination de la résistance au durcissement sous l'effet de la chaleur et de l'air - Partie 1 : Méthode RTFOT

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 en renouvellement permanent. Elle simule le durcissement que subit un liant bitumineux au cours du malaxage dans une centrale d'enrobage.
La méthode décrite n'est pas applicable à certains liants modifiés, ou ceux dont la viscosité est trop élevée pour permettre un renouvellement du film. L'échantillon peut baver hors de la fiole et couler sur les éléments chauffants de l'étuve au cours de l'essai.
L'essai est désigné par RTFOT, ce qui signifie : Rolling Thin Film Oven Test.
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.

cm². The oven shall incorporate an air flow around the side walls and ceiling. The air plenum shall be of uniform thickness (38 ± 3) mm (Figure 1a)). The inside of the oven shall be equipped with a vertical circular aluminium carriage with a diameter of (300 ± 10) mm (Figure 2a)). The horizontal axis of the circular carriage is located (160 ± 10) mm from the upper inside wall of the oven, excluding the air plenum. The carriage shall be provided with suitable openings and spring clips for firmly holding eight glass containers in a horizontal position (Figure 2b)). The carriage shall be mechanically driven by a 20 mm diameter shaft at a speed of
(15,0 ± 0,2) r/min. The front surface of the carriage shall be (110 ± 5) mm from the rear inside wall of the oven. On the upper surface and at the midpoint of the width of the oven and (150 ± 5) mm from the front face of the carriage, a squirrel cage-type fan shall be mounted with an outside diameter of (135 ± 5) mm and a thickness of (75 ± 5) mm and turned at (1 725 ± 100) r/min by an externally mounted motor. The fan shall be set so that it turns in an opposite direction to its vanes. The air flow characteristics shall be suction from the floor of the oven then flow along the walls in the sheaths fitted for this purpose and exhaust at the upper surface through the fan (Figures 1a) and 1b)). The oven shall be equipped with a thermostat capable of maintaining a constant temperature to ± 0,5 °C. The corresponding regulation probe shall be situated on the right side of the oven as described in Figure 1 or symmetrically on the left side. The temperature shall be recorded inside the oven with the reading point (25 ± 5) mm below a horizontal line through the axle of the carriage, (50 ± 5) mm from the inside wall and (115 ± 5) mm from the front face of the carriage. The heating capacity shall be sufficient to bring the oven back to the test temperature within a 10 min period after insertion of the containers. The oven shall be equipped with an air jet positioned to blow heated air into each container at its lowest point of travel. The air jet shall have an outlet orifice with a diameter of (1,0 ± 0,1) mm connected to a copper tubing (see EN 12735-1) with an external diameter of (8,0 ± 0,1) mm and a length of (7,60 ± 0,05) m. This tube shall be coiled to lie flat on the bottom of the oven and lead to a source of oil-free, dried and dust-free air. The
