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.

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).

1 Scope
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.

3.1
short term ageing
means the RTFOT (Rolling Thin Film Oven Test) ageing procedure according to EN 12607-1
Note 1 to entry: The main procedure is the RTFOT at 163 °C. For some highly viscous polymer modified
bitumens, where the viscosity is too high to provide a moving film, it is not possible to carry out the RTFOT at the
reference temperature of 163 °C. In such cases the procedure shall be carried out at 180 °C in accordance with
EN 12607-1. The selected conditioning temperature shall be declared.
3.2
long term ageing
means the RTFOT ageing procedure according to EN 12607-1, followed by the PAV (Pressure Ageing
Vessel) ageing procedure, according to EN 14769
Note 1 to entry: EN 14769 allows a wide range of conditions to apply; for the polymer modified binders covered
by this standard PAV conditioning should be carried out at T = 100 °C and for t = (20 h ± 10 min).
3.3
DV
declared value (DV) made available by the supplier of the bituminous binder; DVs are to be considered
as typical, single values, and are not intended to be used as requirements or interpreted as limiting
values
4 Product characteristics
4.1 General
European product standards cover a large variety of road materials for different applications, to
accommodate local traffic loads and climatic conditions.
This document is a framework of specifications and the appropriate class for each characteristic of
polymer modified bitumens is chosen from Table 1 and Table 2.
4.2 Consistency at intermediate service temperature
Consistency at intermediate service temperature for polymer modified bitumens is addressed by the
needle penetration in 0,1 mm at 25 °C or 15 °C. The test method is described in EN 1426 and
temperatures are selected according to the applicability of the test method, described in the test
standard.
4.3 Consistency at elevated service temperature
Consistency at elevated service temperature for polymer modified bitumens is addressed by the
softening point ring and ball in °C as described in EN 1427.

oSIST prEN 14023:2020
prEN 14023:2020 (E)
4.4 Resistance to flow and deformation
Resistance to flow and deformation for polymer modified bitumens is characterized by non-recoverable
-1
creep compliance [kPa ] and % recovery [%] from MSCRT (Multiple Stress Creep and Recovery Test)
according to EN 16659, after short-term ageing.
4.5 Durability of consistency at low service temperature
Durability of consistency at low service temperature for polymer modified bitumens is characterized by
T (S = 300 MPa) in °C and m-value [−] at T (S = 300 MPa) measured using the BBR (Bending Beam
Rheometer) test procedure (EN 14771) after long term ageing.
For details, see also informative Annex A to this document.
4.6 Cohesion
Three different test methods are used to address cohesion of polymer modified bitumens: force
ductility, tensile test and pendulum test. It is intended that the most appropriate cohesion test method
shall be used, depending on the intended use and application, at the discretion of the manufacturer. The
manufacturer shall state the test method used.
Force ductility (EN 13589) and tensile test (EN 13587) may be used for all binders. Force Ductility is
2
expressed in J/cm at a given test temperature and elongation of the test specimen. Tensile test results
2
are expressed in J/cm at a given test temperature.
The pendulum test according to EN 13588 may only be used for binders used for surface dressing, bond
2
coats, slurry-surfacing and micro-surfacing. Test results are expressed in J/cm .
4.7 Strain recovery
Strain recovery may be important for some applications, e.g. on bridge decks, as a characteristic to
address other cohesion elements not addressed in 4.6. Strain recovery of polymer modified bitumens is
characterized by elastic recovery (EN 13398) in % at 25 °C or 10 °C. Test temperatures are selected
according to the climate conditions at application.
4.8 Durability of strain recovery
Durability of strain recovery of polymer modified bitumens is characterized by elastic recovery
(EN 13398) in % at 25 °C or 10 °C after short-term ageing. Test temperatures are selected according to
the climate conditions at application.
4.9 Viscoelastic behaviour
Viscoelastic behaviour is addressed by T (G* = 15 kPa) [°C] and respective phase angle [°] for fresh
binders, and by T (G* = 15 kPa) [°C] and respective phase angle [°] together with T (G* = 5 MPa) [°C]
and respective phase angle [°] for short-term aged binders determined according to EN 14770.
For details, see also informative Annex A to this document.
It is recommended to store all raw data from temperature sweep measurements in order to allow other
calculations and to prepare future revisions of this document.
4.10 Durability of viscoelastic behaviour
Durability of viscoelastic behaviour is addressed by comparison of T (G* = 15 kPa) [°C] and respective
phase angle [°] for fresh, short-term aged and long term aged binders and by comparison of
T (G* = 5 MPa) [°C] and respective phase angle [°] for short-term and long term aged binders
determined according to EN 14770.

For details, see also informative Annex A to this document.
It is recommended to store all raw data from temperature sweep measurements in order to allow other
calculations and to prepare future revisions of this document.
4.11 Temperature sensitivity
Temperature sensitivity is addressed by comparison of T (G* = 15 kPa) [°C] and respective phase angle
[°] to T (G* = 5 MPa) [°C] and respective phase angle [°] for short-term aged binders, and by comparison
of T (G* = 15 kPa) [°C] and respective phase angle [°] to T (G* = 5 MPa) [°C] and respective phase angle
[°] for long term aged binders, determined according to EN 14770.
For details, see also informative Annex A to this document.
It is recommended to store all raw data from temperature sweep measurements in order to allow other
calculations and to prepare future revisions of this document.
4.12 Other characteristics
4.12.1 Change in mass after short-term ageing
Change in mass after short-term ageing (RTFOT) according to EN 12607-1 is expressed in %.
4.12.2 Flash point
Flash point [°C] shall be determined by the Cleveland open cup method in EN ISO 2592 for normal
specification purposes.
The Pensky-Martens closed cup method (see EN ISO 2719) may be used to investigate possible
contamination but is likely to give lower values than the Cleveland open cup method.
4.12.3 Dynamic viscosity
Information on dynamic viscosity [Pa⋅s] according to EN 13302 may be of assistance for handling of
polymer modified binders. The value of dynamic viscosity reported is a typical, single value, and is not
intended to be used as a requirement or interpreted as a limiting value.
4.12.4 Homogeneity and storage stability
Homogeneity is necessary for polymer modified bitumens. The tendency of polymer modified bitumens
to separate during storage may be assessed by the storage stability test (see EN 13399). If the product
does not fulfil the properties in Table 2, that is difference in needle penetration in 0,1 mm according to
EN 1426, or difference in softening point in °C according to EN 1427, information shall be given by the
supplier regarding storage conditions for the polymer modified bitumens to avoid separation of the
components and to ensure the homogeneity of the product.
4.13 Release of dangerous substances
Materials used in products shall not release any dangerous substances in excess of the maximum
permitted levels specified in a relevant European standard for the material or permitted in the national
regulations of the member state of destination.

a
For some highly viscous polymer modified bitumens it is not possible to carry out the RTFOT at the reference temperature of 163 °C because no continuous binder film is formed. In this
case the procedure shall be carried out at 180 °C.
b
One cohesion method shall be chosen based on end application. Force Ductility (EN 13589) and Tensile test (EN 13587) may be used for all binders, but the pendulum test (EN 13588)
may only be used for binders used for surface dressing, bond coats, slurry-surfacing and micro-surfacing. For Force Ductility, classes for cohesion energy, temperature and elongation shall be
selected. Elongation class 1 should be selected only in cases where 400 mm elongation is not deemed to be necessary. For Tensile Test, cohesion energy and temperature shall be selected.
c
Change in mass after ageing (RTFOT) can be positive or negative.
