Bitumen and bituminous binders - Recovery of binder from bituminous emulsion or cut-back or fluxed bituminous binders - Part 1: Recovery by evaporation

This European Standard specifies a method for the recovery of binder from a bituminous emulsion or from a cut-back or fluxed bitumen after conditioning at ambient temperature for 24 h followed by 24 h at 50 °C, in such a way that will enable further testing with minimum changes of the binder characteristics.
It applies to all types of bituminous emulsions, modified with polymers or non-modified, as well as to all types of cut-back and fluxed bitumen, both modified with polymers and non-modified.
For cut-back and fluxed bituminous binders, this test method is only an intermediate step and should be followed by the stabilisation procedure specified by EN 13074-2. Direct testing of the recovered binder is however used to evaluate the setting ability of fluxed bituminous binders made with vegetal fluxes.
NOTE   The recovered binder is not necessarily identical to the initial binder.
WARNING - The use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. The hazards associated with the use of this method have been assessed using cut-back bitumen containing 10 % kerosene and 90 % 160/220 penetration grade bitumen and were found low enough to be acceptable. However it is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Bitumen und bitumenhaltige Bindemittel - Rückgewinnung des Bindemittels aus Bitumenemulsion oder verschnittenem oder gefluxtem Bindemittel - Teil 1: Rückgewinnung durch Verdunstung

Diese Europäische Norm legt ein Verfahren zur Rückgewinnung von Bindemittel aus einer Bitumenemulsion oder aus verschnittenem oder gefluxtem Bitumen nach einer Konditionierung für 24 h bei Umgebungstemperatur und anschließend für 24 h bei 50 °C fest, so dass weitere Prüfungen bei nur minimalen Veränderungen der Eigenschaften des Bindemittels ermöglicht werden.
Sie ist anwendbar für alle Arten von Bitumenemulsionen, polymermodifiziert oder nicht modifiziert, sowie für alle Arten von verschnittenem und gefluxtem Bitumen, sowohl polymermodifiziert als auch nicht modifiziert.
Für verschnittene und gefluxte bitumenhaltige Bindemittel ist dieses Verfahren nur ein Zwischenschritt und sollte vom Stabilisierungsverfahren nach EN 13074-2 gefolgt werden. Die direkte Prüfung von rückgewonnenem Bindemittel wird jedoch zur Abschätzung des Absetzvermögens von gefluxten bitumenhaltigen Bindemitteln, die mit pflanzlichen Fluxmitteln hergestellt wurden, verwendet.
ANMERKUNG   Das rückgewonnene Bindemittel ist nicht unbedingt mit dem ursprünglichen Bindemittel identisch.
WARNUNG - Die Anwendung dieses Dokuments schließt auch den Umgang mit gefährlichen Substanzen und Ausrüstungen sowie die Durchführung gefährlicher Arbeitsschritte ein. Dieses Dokument beansprucht nicht, sämtliche mit seiner Anwendung verbundenen Sicherheitsprobleme zu behandeln. Die mit der Anwendung dieses Verfahrens verbundene Gefährdung wurde mit verschnittenem Bitumen mit 10 % Kerosin und mit 90 % Bitumen der Penetration 160/220 ermittelt und war niedrig genug, um als akzeptabel angesehen zu werden. Jedoch liegt es in der Verantwortung des Anwenders dieses Dokuments, geeignete Vorsichtsmaßnahmen für den Arbeits- und Gesundheitsschutz zu treffen und die Anwendbarkeit einschränkender Vorschriften vor der Anwendung zu bestimmen.

Bitumes et liants bitumineux - Récupération du liant d'une émulsion bitumineuse ou d'un bitume fluidifié ou fluxé - Partie 1 : Récupération par évaporation

La présente Norme européenne décrit une méthode de récupération du liant à partir d’une émulsion de bitume ou d’un bitume fluidifié ou fluxé après un conditionnement à la température ambiante pendant 24 h puis 24 h à 50 °C, de telle manière que des essais ultérieurs puissent être réalisés en modifiant le moins possible les caractéristiques du liant.
Elle s’applique à tous les types d’émulsions de bitume, modifiées avec des polymères ou non modifiées, ainsi qu’à tous les types de bitumes fluidifiés et fluxés, modifiés avec des polymères et non modifiés.
Pour des liants bitumineux fluidifiés ou fluxés, cette méthode d’essai est seulement une étape intermédiaire et doit être suivie par la procédure de stabilisation spécifiée par l’EN 13074-2. L’essai direct du liant récupéré est toutefois utilisé pour évaluer la propriété de durcissement des liants bitumineux contenant des fluxants végétaux.
NOTE   Le liant récupéré peut ne pas être identique au liant original.
AVERTISSEMENT - L'utilisation de la présente Norme européenne implique 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. Les risques découlant de la mise en oeuvre de cette méthode ont été évalués en l’appliquant à un bitume fluidifié contenant 10 % de kérosène et 90 % de bitume de classe de pénétrabilité 160/220. Cette évaluation a conclu à un niveau de risques suffisamment faible pour être acceptable. Cependant, il est de la responsabilité de l'utilisateur de cette Norme européenne de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

Bitumen in bitumenska veziva - Ponovna pridobitev veziva iz bitumenskih emulzij ali rezanih ali fluksiranih bitumenskih veziv - 1. del: Ponovna pridobitev z izhlapevanjem

Ta evropski standard določa metodo za ponovno pridobitev veziva iz bitumenskih emulzij ali rezanih/fluksiranih bitumnov po obdelavi pri temperaturi okolice za 24 ur in nato 24 ur pri 50 °C na tak način, da se omogoči nadaljnje preskušanje z minimalnimi spremembami značilnosti veziva.
Uporablja se za vse vrste bitumenskih emulzij, spremenjenih s polimeri ali nespremenjenih, pa tudi za vse vrste rezanih in fluksiranih bitumnov, spremenjenih s polimeri in nespremenjenih.
Za rezana in fluksirana bitumenska veziva je ta preskusna metoda samo vmesni korak, ki mu mora slediti postopek stabilizacije, določen v standardu EN 13074-2. Za ocenjevanje zmožnosti strjevanja fluksiranih bitumenskih veziv, proizvedenih iz rastlinskih fluksov, se uporablja neposredno preskušanje ponovno pridobljenega veziva.
OPOMBA: Ponovno pridobljeno vezivo ni nujno enako prvotnemu vezivu.
OPOZORILO: Pri uporabi tega dokumenta so lahko prisotni nevarni materiali, postopki in oprema. Ta dokument ne obravnava vseh varnostnih težav, ki se nanašajo na njegovo uporabo. Nevarnosti, povezane z uporabo te metode, so bile ocenjene z uporabo rezanega bitumna, ki vsebuje 10 % kerozina in 90 % bitumna s penetracijo 160/220. Ker so bile dovolj majhne, so bile označene kot sprejemljive. Vendar pa je za vzpostavitev ustreznih varnostnih in zdravstvenih praks ter za določitev uporabnosti regulativnih omejitev pred uporabo odgovoren uporabnik tega dokumenta.
