Bitumen and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)
This European standard specifies a number of methods using a dynamic shear rheometer (DSR) capable of measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear.
From the test, the norm of the complex shear modulus, IG*I, and its phase angle, δ, at a given temperature and frequency can be calculated, as well as the components G', G'', J' and J'' of the complex shear modulus and of the complex compliance.
This method is applicable to un-aged, aged and recovered bituminous binders, cut-backs and bituminous binders stabilised from emulsions.
WARNING — The 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.
Bitumen und bitumenhaltige Bindemittel - Bestimmung des komplexen Schermoduls und des Phasenwinkels - Dynamisches Scherrheometer (DSR)
Diese Europäische Norm legt eine Reihe von Verfahren fest, bei denen ein dynamisches Scherrheometer (DSR) zur Anwendung kommt, mit dem die rheologischen Eigenschaften von bitumenhaltigen Bindemitteln gemessen werden können. Die Durchführung schließt die Bestimmung des komplexen Schermoduls und des Phasenwinkels von Bindemitteln über einen Bereich von Prüffrequenzen und Prüftemperaturen bei der Prü-fung im Oszillations-Modus ein. Aus der Prüfung können sowohl der Betrag des komplexen Schermoduls, *G, und der zugehörige Phasen-winkel, δ, für eine gegebene Temperatur und Frequenz als auch die Komponenten G′, G′′, J′ und J′′ des komplexen Schermoduls und der komplexen Nachgiebigkeit berechnet werden. Dieses Verfahren ist anwendbar für nicht gealterte, gealterte und rückgewonnene bitumenhaltige Bindemittel, verschnittene oder gefluxte Bindemittel sowie aus Emulsionen rückgewonnene, stabilisierte Bindemittel. WARNUNG — Die Anwendung dieser Europäischen Norm kann den Umgang mit gefährlichen Substanzen und Ausrüstungsteilen und die Ausführung gefährlicher Arbeitsgänge einschließen. Diese Europäischen Norm erhebt nicht den Anspruch, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Es liegt in der Verantwortung des Anwenders dieser Europäischen Norm, geeignete Verhaltensregeln für den Arbeits- und Gesundheitsschutz festzulegen und vor der Anwendung zu klären, ob einschränkende Vorschriften zu berücksichtigen sind.
Bitumes et liants bitumineux - Détermination du module complexe en cisaillement et de l'angle de phase - Rhéomètre à cisaillement dynamique (DSR)
La présente Norme européenne traite de plusieurs méthodes faisant appel à un rhéomètre à cisaillement dynamique (DSR) capable de mesurer certaines caractéristiques rhéologiques de liants bitumineux. La procédure repose sur la détermination du module complexe en cisaillement et de l’angle de phase de liants sur une plage de fréquences et de températures d’essai, lorsqu’ils sont testés en cisaillement oscillatoire. À partir des résultats de cet essai, il est possible de calculer la norme du module complexe en cisaillement, IG*I, et son angle de phase, , à une température et à une fréquence données, ainsi que les composantes G', G'', J' et J'' du module complexe en cisaillement et de la complaisance complexe. Cette méthode est applicable aux liants bitumineux neufs, vieillis et récupérés, ainsi qu’aux liants bitumineux fluidifiés et aux liants bitumineux stabilisés à partir d’une émulsion. AVERTISSEMENT — L'utilisation de la présente Norme européenne peut impliquer l'intervention de produits, d'opérations et d'équipements à caractère dangereux. Cette Norme européenne n'est pas censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de son utilisateur d'établir des règles d'hygiène et de sécurité appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
Bitumen in bitumenska veziva - Ugotavljanje kompleksnega strižnega modula in faznega kota - Dinamični strižni reometer (DSR)
Ta evropski standard določa številne metode, pri katerih se uporablja dinamični strižni reometer (DSR) za ugotavljanje reoloških lastnosti bitumenskih veziv. Postopek zajema ugotavljanje kompleksnega strižnega modula in faznega kota veziv za različne frekvence preskušanja in temperature pri preskušanju pod oscilatornimi strižnimi pogoji. Na podlagi preskusa je mogoče izračunati normo kompleksnega strižnega modula, IG*I, in njegovega faznega kota, δ, pri dani temperaturi in frekvenci ter komponente G', G'', J' in J'' kompleksnega strižnega modula in kompleksne skladnosti. Ta metoda se uporablja za nestarana, starana in ponovno pridobljena bitumenska veziva, rezana bitumenska veziva in bitumenska veziva, stabilizirana iz emulzij.
