Bituminous mixtures - Test methods for hot mix asphalt - Part 3: Bitumen recovery: Rotary evaporator
This document describes a test method for the recovery of soluble bitumen from bituminous mixtures used in road, airfield or similar pavements in a form suitable for further testing. The test can be undertaken on either loose or compacted asphalt materials. The procedure is suitable for the recovery of paving grade bitumens, for which materials this European Standard is the reference method. The fractionating column procedure (see EN 12697-4) is the reference method for mixtures containing volatile matter such as cut-back bitumen.
For recovery of polymer modified bitumens, the rotary evaporator procedure is recommended.
Asphalt - Prüfverfahren für Heißasphalt - Teil 3: Rückgewinnung des Bindemittels: Rotationsverdampfer
Dieses Dokument beschreibt ein Prüfverfahren, mit dem aus Asphalt, der zum Bau von Straßen, Flugplätzen und ähnlichen Verkehrsflächen ver¬wendet wurde, lösliches Bindemittel in einer Form zurückgewonnen wird, die für weitere Prüfungen geeignet ist. Die Prüfung kann entweder an losem oder an verdichtetem Asphalt durchgeführt werden. Dieses Verfahren eignet sich nur zur Rückgewinnung von Straßenbaubitumen, für die das in dieser Europäischen Norm angegebene Verfahren das Referenzverfahren ist. Das Verfahren mit der Fraktionierkolonne (siehe EN 12697 4) ist das Referenzverfahren für Mischgüter, die flüchtige Bestandteile enthalten, wie z. B. verschnittenes Bitumen.
ANMERKUNG Für die Rückgewinnung polymermodifizierten Bitumens wird der Rotationsverdampfer empfohlen.
Mélanges Bitumineux - Méthodes d'essai pour enrobés à chaud - Partie 3: Extraction des bitumes à l'évaporateur rotatif
Le présent document décrit une méthode d'essai permettant de récupérer du bitume soluble de mélanges bitumineux utilisés sur les routes, les terrains d'aviation ou chaussées similaires sous une forme se prêtant à des essais complémentaires. L'essai peut être réalisé sur des matériaux enrobés foisonnés ou compactés. La procédure convient uniquement à la récupération de bitumes routiers de grades usuels, pour lesquels cette Norme européenne est une méthode de référence. La méthode à la colonne à distiller (voir EN 12697-4) est la méthode de référence pour les mélanges qui contiennent des produits volatils tels que des fluxants.
Pour la récupération des bitumes modifiés par des polymères, la méthode à l’évaporateur rotatif est recommandée.
Bitumenske zmesi - Preskusne metode za vroče asfaltne zmesi - 3. del: Ugotavljanje deleža veziva: rotacijski uparjalnik
Ta dokument opisuje preskusno metodo za ugotavljanje deleža topnega bitumena v bitumenskih zmeseh za ceste, vozišča letališč ali podobna vozišča v obliki, ki je primerna za nadaljnje preskušanje. Preskus se lahko opravi na razrahljanih ali zgoščenih asfaltnih materialih. Postopek je primeren za ugotavljanje deleža cestnogradbenih bitumnov, pri čemer je ta evropski standard referenčna metoda za njihov material. Kolonska frakcionirana destilacija (glej EN 12697-4) je referenčna metoda za zmesi, ki vsebujejo hlapne snovi, kot je rezani bitumen. Za ugotavljanje deleža bitumnov, modificiranih s polimeri, se priporoča postopek z rotacijskim uparjalnikom.

The Scope is clarified. The definitions for precision and associated terms have been removed. Remaining solvent is redefined as solvent residue. The minimum evaporation capacity of solvent has been reduced from 1,0 l/h to 0,85 l/h. The container no longer has to be made of glass. The warning note about solvent is clarified. Silicon grease is permitted as a seal. Silica gel has been corrected. Pouring of bitumen solution has been edited. Ash content reference to EN 12697-1 has been corrected. Maximum time for bitumen recovery distillation is reduced. Check for air leaks has been removed. First phase temperature and second phase pressure with dichloromethane has been changed. The minimum final pressure has been made relevant to first phase pressure instead of fixed value for all solvents. The use of nitrogen to prevent the bitumen from ageing has been added. The note on expected time for distillation has been removed.
