Bitumen and bituminous binders - Determination of the elastic recovery of modified bitumen

This European Standard specifies a method for the determination of the elastic recovery of bituminous binders in a ductilometer at the test temperature (typically 25°C or 10°C; other temperatures can be used).
It is especially applicable to bituminous binders modified with thermoplastic elastomers, but can also be used with other bituminous binders which generate only small recovery.
WARNING - The use of this European Standard may 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 determine the applicability of regulatory limitations prior to use.

Bitumen und bitumenhaltige Bindemittel - Bestimmung der elastischen Rückstellung von modifiziertem Bitumen

Diese Europäische Norm legt ein Verfahren für die Bestimmung der elastischen Rückstellung von bitumen-haltigen Bindemitteln in einem Duktilometer bei einer gegebenen Prüftemperatur fest (üblicherweise 25 °C oder 10 °C; es können aber auch andere Temperaturen angewendet werden).
Sie gilt besonders für bitumenhaltige Bindemittel, die mit thermoplastischen Elastomeren modifiziert sind, kann aber auch auf andere bitumenhaltige Bindemittel angewendet werden, die nur eine geringe Rück-stellung aufweisen.
WARNUNG - Die Anwendung dieser Europäischen Norm kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Europäische Norm beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Europäischen Norm, vor ihrer Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Maßnahmen eingehalten werden.

Bitumes et liants bitumineux - Détermination du retour élastique des bitumes modifiés

La présente norme européenne prescrit une méthode de détermination du retour élastique des liants bitumineux dans un ductilimètre à la température d’essai (typiquement 25 °C ou 10 °C ; d’autres températures peuvent être utilisées).
Elle s’applique plus particulièrement aux liants bitumineux modifiés à l’aide d’élastomères thermoplastiques mais peut aussi être utilisée pour d’autres liants bitumineux possédant un faible retour élastique.
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. 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.

Bitumen in bitumenska veziva - Določevanje elastičnega povratka modificiranih bitumnov

Ta evropski standard opredeljuje metodo za določevanje elastičnega povratka bitumenskih veziv pri preskusni temperaturi (običajno 25 °C ali 10 °C; lahko se uporabijo druge temperature).
Uporablja se zlasti za bitumenska veziva, modificirana s plastomernimi elastomeri, vendar se lahko uporablja tudi z drugimi bitumenskimi vezivi z majhnim povratkom.
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.

EN 13398:2017 (E) 3 European foreword This document (EN 13398:2017) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2018, and conflicting national standards shall be withdrawn at the latest by June 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13398:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Compared to EN 13398:2010, the major changes in the present standard are: — Incorrect reference to ISO 5725 for rounding off values removed from Clause 2 and 9; — the possibility of alternative measuring conditions are now mentioned in Clause 4 Principle; — reference to ASTM D113 has been deleted in 5.1 and Bibliography; — in 6.3 the maximum temperature for the pre-heating of moulds is linked to the softening point (ring and ball) of the specimen or to 70 °C if softening point (ring and ball) is not known; — Clause 11 Other test conditions is now part of Clause 4 Principle; — several test methods are now referenced in the Bibliography. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13398:2017 (E) 5 4 Principle A bituminous binder specimen is stretched at the test temperature and a constant rate of 50 mm/min to a predetermined elongation (200 mm). The bitumen thread thus produced is cut in the middle to obtain two half-threads. After a predetermined time of 30 min for recovery has elapsed, the shortening of the half-threads is measured and expressed as the percentage of the elongation length. Although this procedure is typically performed at a test temperature of 25 °C or 10 °C, it may be useful to perform it at different temperatures, especially for soft or highly modified binders. If the sample breaks before reaching 200 mm (premature break), the length at break and its elastic recovery shall be measured and then the results can be considere
