Bitumen and bituminous binders - Determination of the resistance to hardening under 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 which most bituminous binders undergo 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 suitable for other bituminous binders than paving grade bitumen, but the reference temperature might give excessive hardening that do not resemble real conditions during mixing at the plant. The method may not represent the hardening that occurs during mixing of warm mix binders.
The method is referred to as RTFOT, i.e. Rolling Thin Film Oven Test.
WARNING - Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European 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 13074-2.

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

Dieser Teil von EN 12607 legt ein Verfahren zur Bestimmung der kombinierten Wirkungen von Wärme und Luft auf einen rollierenden dünnen Film aus Bitumen oder bitumenhaltigem Bindemittel fest, mit dem die Ver-härtung der meisten bitumenhaltigen Bindemittel während des Mischvorgangs in einer Asphaltmischanlage simuliert wird.
Das beschriebene Verfahren ist bei einigen modifizierten Bindemitteln und bei Bindemitteln, deren Viskosität zu hoch ist, sodass sich kein rollierender Film erzeugen lässt, nicht anwendbar. Derartige Proben können über den Glasbehälter hinaus kriechen und während der Prüfung auf die Heizelemente der Wärmekammer fließen. Das Verfahren eignet sich für andere bitumenhaltige Bindemittel als Straßenbaubitumen, die festge¬legte Referenztemperatur kann jedoch zu übermäßiger Verhärtung führen, die keine Ähnlichkeit mit den wäh¬rend des Mischvorgangs in einer Asphaltmischanlage tatsächlich auftretenden Bedingungen hat. Das Verfah¬ren kann eine Verhärtung, wie sie während des Mischens von warmen Mischbindemitteln auftritt, möglicher¬weise nicht wiedergeben.
Die Prüfung wird als RTFOT-Verfahren (“Rolling Thin Film Oven Test”) bezeichnet, d. h. Prüfung mit rollieren-dem dünnen Film.
WARNUNG — Die Anwendung dieser Norm kann den Umgang mit gefährlichen Substanzen und Aus-rüstungsteilen und die Ausführung gefährlicher Arbeitsgänge einschließen. Diese Norm erhebt nicht den Anspruch, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Es liegt in der Verantwortung des Anwenders dieser Norm, geeignete Verhaltensregeln zur Sicherheit und Gesundheit festzulegen und vor der Anwendung festzustellen, ob einschränkende Vorschriften einzu¬halten sind.
Falls die Wahrscheinlichkeit besteht, dass ein Bindemittel flüchtige Bestandteile enthält, sollte dieses Verfahren nicht angewendet werden. Bei verschnittenem Bitumen und Bitumenemulsionen sollte es nicht angewendet werden, bevor diese Produkte z. B. nach EN 13074 2 stabilisiert wurden.

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

Cette partie de l’EN 12607 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 en simulant le durcissement que subissent la plupart des liants 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 s’écouler hors du récipient en verre et couler sur les éléments chauffants de l’étuve au cours de l’essai. La méthode convient pour d’autres liants bitumineux que les bitumes routiers, mais la température de référence pourrait donner un durcissement excessif qui ne ressemble pas aux véritables conditions pendant l’enrobage en usine. La méthode peut ne pas représenter le durcissement qui advient pendant l’enrobage des liants à chaud.
L'essai est désigné par RTFOT, c’est-à-dire Rolling Thin Film Oven Test, essai d’un film fin en rotation à l’étuve.
AVERTISSEMENT — L'utilisation de la présente Norme européenne peut nécessiter des produits, des opérations et des équipements dangereux. La présente norme européenne n’est pas censée aborder tous les problèmes de sécurité concernés par son utilisation. Il est de la responsabilité de l'utilisateur de la présente Norme européenne de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer si des restrictions réglementaires sont applicables avant son utilisation.
Si la présence de composés volatils dans le liant est probable, il convient de ne pas utiliser le présent mode opératoire. Il convient de ne pas l'utiliser pour les bitumes fluidifiés ou les émulsions bitumineuses, avant la stabilisation de ces produits, réalisées, par exemple, conformément à l’EN 13074-2.

Bitumen in bitumenska veziva - Določanje odpornosti proti otrjevanju pod vplivom toplote in zraka - 1. del: Metoda RTFOT

Ta evropski standard določa metodo merjenja skupne vplive toplote in zraka na tanko premikajočo se plast bitumna ali bitumenskega veziva s simulacijo otrjevanja, ki ga med mešanjem v asfaltnem obratu prestane večina bitumenskih veziv.
Opisana metoda se ne uporablja za nekatera spremenjena veziva ali veziva s previsoko viskoznostjo, da se zagotovi premikajoča se plast. Med preskusom lahko vzorec spolzi iz steklene posode in steče na grelne elemente pečice. Metoda je primerna za vsa bitumenska veziva, razen za cestnogradbene bitumne, vendar lahko referenčna temperatura povzroči prekomerno otrjevanje, ki ni podobno otrjevanju pod pravimi pogoji med mešanjem v asfaltnem obratu. Metoda morda ne predstavlja otrjevanja, ki nastane med mešanjem toplih veziv.
Metoda se imenuje RTFOT.
OPOZORILO – pri uporabi tega evropskega standarda so lahko prisotni nevarni materiali, postopki in oprema. Ta evropski standard ne obravnava vseh varnostnih težav, ki se nanašajo na njegovo uporabo. Za vzpostavitev ustreznih varnostnih in zdravstvenih praks ter za določitev uporabnosti regulativnih omejitev pred uporabo je odgovoren uporabnik tega evropskega standarda.
Če obstaja verjetnost prisotnosti hlapnih komponent v vezivu, se tega postopka ne sme uporabiti. Ne sme se uporabljati za rezani bitumen ali bitumenske emulzije, preden so ti produkti stabilizirani, npr. v skladu s standardom EN 13074-2.

1 Scope
This part of EN 12607 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 which most bituminous binders undergo 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 suitable for other bituminous binders than paving grade bitumen, but
the reference temperature might give excessive hardening that do not resemble real conditions during mixing
at the plant. The method may not represent the hardening that occurs during mixing of warm mix binders.
The method is referred to as RTFOT, i.e. Rolling Thin Film Oven Test.
WARNING — Use of this European Standard can involve hazardous materials, operations and
equipment. This European Standard does not purport to address all of the safety problems associated
with its use. It is the responsibility of the user of this European 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 13074-2.

3 Principle
A moving film of bituminous binder is heated in an oven to a specified temperature for a given period of time
with a constant supply of air.
The effects of heat and air are determined based on the change in mass (expressed as a percentage) or on
the change in the bituminous binder's characteristics such as penetration (EN 1426), softening point
(EN 1427) or dynamic viscosity (EN 12596), before and after the period in the oven.
The reference temperature of this conditioning is 163 °C.

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 (Figure 1, a) and b)).

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
orifice of the tubing shall be between 5 mm and 10 mm from the opening in the glass container. The air jet
shall blow along the main axis of the glass container.
