Bitumen and bituminous binders - Specification framework for polymer modified bitumens
This document provides a framework for specifying a range of characteristics as well as applicable test methods for polymer modified bitumens, which are suitable for use in the construction and maintenance of roads, airfields and other paved areas, together with information on assessment and verification of constancy of performance. Polymer modified bitumen is defined in EN 12597.
This document describes the performance for characteristics of polymer modified bitumens, as shown in Table 1 and Table 2. It gives information for Declaration of Performance, selection of the grades, characteristics and test methods.
This framework covers the following essential characteristics:
- consistency at intermediate service temperature;
- consistency at elevated service temperature;
- viscoelastic behaviour;
- cohesion;
- resistance to flow and deformation;
- temperature sensitivity;
- strain recovery;
- durability of strain recovery;
- durability of consistency at low service temperature;
- durability of viscoelastic behaviour.
The characteristics of "adhesion" and "setting ability" are addressed by tests used on either the finished asphalt mixtures or on aggregate bitumen combinations, i.e. EN 12697-1, EN 12697-11, EN 12697-12, EN 12697-26 [2 to 5], rather than tests on the bitumen itself.
"Adhesion" is addressed by tests carried out on the finished asphalt mixtures.
"Setting ability" is the return of the polymer modified binder to its normal semi solid state as it returns to ambient temperature; this is a natural result of the cooling of the hot polymer modified bitumen after application and thus not addressed here.
The nomenclature of polymer modified bitumen comprises the nominal penetration range and the minimum softening point, e.g. PMB 45/80 60.
Bitumen und bitumenhaltige Bindemittel - Rahmenwerk für die Spezifikation von polymermodifizierten Bitumen
Dieses Dokument bietet ein Rahmenwerk für die Festlegung eines Bereichs von Merkmalen und anwendbare Prüfverfahren für polymermodifizierte Bitumen, die für die Verwendung beim Bau und bei der Instandhaltung von Straßen, Flugplätzen und sonstigen befestigten Flächen geeignet sind, zusammen mit Informationen zur Bewertung und Überprüfung der Leistungsbeständigkeit. Polymermodifiziertes Bitumen wird in EN 12597 festgelegt.
Dieses Dokument beschreibt die Leistung für Merkmale von polymermodifizierten Bitumen, wie sie in Tabelle 1 und Tabelle 2 gezeigt werden. Es gibt Informationen zu Leistungserklärung, Auswahl der Sorten, Merkmale und Prüfverfahren.
Dieses Rahmenwerk deckt folgende Wesentliche Merkmale ab:
- Konsistenz bei mittlerer Gebrauchstemperatur;
- Konsistenz bei erhöhter Gebrauchstemperatur;
- viskoelastisches Verhalten;
- Kohäsion;
- Widerstand gegen Fließen und Verformung;
- Temperaturempfindlichkeit;
- Dehnungsrückstellung;
- Dauerhaftigkeit der Dehnungsrückstellung;
- Dauerhaftigkeit der Konsistenz bei geringer Gebrauchstemperatur;
- Dauerhaftigkeit des viskoelastischen Verhaltens.
Mit den Merkmalen "Adhäsion" und "Abbindefähigkeit" befassen sich Prüfungen, die entweder an fertigen Asphaltmischungen verwendet werden oder an Gesteinskörnung-Bitumenmischungen, d. h. EN 12697-1, EN 12697-11, EN 12697-12, EN 12697-26 [2] bis [5], durchgeführt werden anstelle von Prüfungen an dem Bitumen selbst.
Mit "Adhäsion" befassen sich Prüfungen, die an den fertigen Asphaltmischengen durchgeführt werden.
Die "Abbindefähigkeit" ist die Rückkehr des polymermodifizierten Bindemittels in seinen üblichen, halbfesten Zustand, wenn es wieder auf Umgebungstemperatur abkühlt; dies ist ein natürliches Ergebnis der Abkühlung des heißen polymermodifizierten Bitumens nach der Anwendung und wird hier deshalb nicht behandelt.
Die Nomenklatur von polymermodifiziertem Bitumen umfasst den Nennbereich der Penetration und den Mindesterweichungspunkt, z. B. PMB 45/80 60.
Bitumes et liants bitumineux - Cadre de spécifications des bitumes modifiés par des polymères
Le présent document fournit un cadre pour la spécification des caractéristiques et des méthodes d’essai appropriées pour les bitumes modifiés par des polymères, dont l’usage convient pour la construction et l’entretien des routes, des pistes d’aéroport et des autres chaussées. Ce document fournit en outre des informations sur l’évaluation et la vérification de la constance des performances. La définition d’un bitume modifié par un (des) polymère(s) est donnée dans l’EN 12597.
Le présent document définit les niveaux de performance pour les caractéristiques des bitumes modifiés par des polymères, tels que présentés dans le Tableau 1 et le Tableau 2. Il donne aussi les informations pour la Déclaration de Performance, la sélection des classes, le choix des caractéristiques et des méthodes d’essai associées.
Ce cadre de spécification couvre les caractéristiques essentielles suivantes :
- consistance à température de service intermédiaire ;
- consistance à température de service élevée ;
- comportement viscoélastique ;
- cohésion ;
- résistance au fluage et à la déformation ;
- sensibilité à la température ;
- recouvrance en déformation ;
- durabilité de la recouvrance en déformation ;
- durabilité de la consistance à basse température de service ;
- durabilité du comportement viscoélastique ;
Les caractéristiques "d'adhésion" ou "d'aptitude à la reprise de cohésion" sont déterminées à l'aide de méthodes d'essai, sur les enrobés bitumineux ou sur des couples liant-granulats, telles que l'EN 12697-1, l'EN 12697-11, l'EN 12697-12, l'EN 12697-26 [2 à 5], plutôt que sur le bitume modifié par des polymères lui-même.
"L'adhésion" est déterminée par des essais pratiqués sur les enrobés en tant que produits finis.
"L'aptitude à la reprise de cohésion" caractérise la façon dont le bitume modifié par des polymères revient à son état normal semi-solide lorsqu'il se refroidit à température ambiante suite à sa mise en oeuvre. De fait ce type de caractéristiques est exclu du champ d'application du présent document.
La nomenclature d'un bitume modifié par des polymères contient respectivement les indications de l’intervalle de pénétrabilité et du point de ramollissement minimum, par exemple PMB 45/80-60.

Figure 1 — European standards for Bitumens
Introduction
This document is part of a family of product standards for bitumen and bituminous binders for paving
applications.
The general principle adopted in the development of EN 12591 [1], Bitumen and bituminous binders —
Specifications for paving grade bitumens, was to provide a range of grades suitable for the manufacture
of the materials for road construction and maintenance used, and the climatic and traffic conditions
encountered, in all the Member States. This document provides a framework for specifying a range of
characteristics and applicable test methods suitable for polymer modified bitumens.
It is compulsory for the full specification to be published in all EU and EFTA countries. However, it is
permitted for each country to define the most suitable grades and classes.
Changes to the previous version of this document (EN 14023:2010) are:
— updated terminology for essential characteristics referring to draft standardization request;
— display in two tables only;
— addition of three classes for characteristics for soft PMB by needle penetration [EN 1426] at 15 °C;
— addition of the essential characteristics of viscoelastic behaviour, resistance to flow and
deformation, temperature sensitivity, and durability of viscoelastic behaviour;
— addition of two classes for characteristic of softening point ring and ball for soft PMB [EN 1427];
— addressing low service temperature characteristics by BBR instead of Fraass Breaking Point, on
long term aged instead of fresh binders, and insertion of respective levels;
— change in display of essential characteristics for cohesion by Force Ductility method, addition of
three levels for minimum Cohesion Energy, and addition of elongation as declared value;
— addition of three levels for minimum Cohesion Energy by tensile test, and addition of three test
temperatures;
— addition of three minimum levels of pendulum test results;
— deletion of characteristics on retained needle penetration and change in softening point ring and
ball after short term ageing;
— deletion of plasticity range;
— change of levels for difference in penetration for storage stability;
— deletion of Annex A and Annex B;
— update of Clause 6 and Annex ZA according to current guidance document TF N 548 Rev.1 (for
Clause 6) and TF N 687 rev1 (for Annex ZA).
