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.
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
expressed in J/cm at a given test temperature and elongation of the test specimen. Tensile test results
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
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.
5 Testing, assessment and sampling methods
Samples of bulk products shall be taken as described in EN 58.
Test samples shall be taken from the laboratory samples, and prepared for testing, as described in
EN 12594.

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. The selected conditioning temperature shall be declared.
b -1
For some viscometers (e.g. when testing highly viscous binders) at 135 °C, the required shear rate (100 s ) may not be achievable. If different testing parameters (i.e. shear rate or
temperature) are used, those condition(s) shall be clearly stated. For Dynamic viscosity testing EN 13302 (rotating spindle) and EN 13702 (cone and plate) may be used. However, in case of
dispute, EN 13302 shall be the reference method.
c
Storage conditions of the polymer modified binder shall be given by the supplier. Homogeneity is necessary for polymer modified bitumen. 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 fulfill the properties in Table 2 classes 2 to 5, information shall be given by
the supplier regarding storage conditions (such as recommended maximal storage time, recommended stirring, recommended quality checks to ensure binder homogeneity) for the polymer
modified bitumen to avoid separation of the components and to ensure the homogeneity of the product.
d
The temperatures T0, T1, T2, T3 and T4 are determined by logarithmic interpolation from two temperatures, one leading to a modulus below and one above the target modulus. The
corresponding values of delta shall be determined by linear interpolation.
e
According to EN 14770, testing should be carried out within the linear viscoelastic range.
f
For some binders, it is not possible to carry out the MSCRT at 60 °C. In this case the test may be carried out at a different temperature. The selected temperature shall be declared.

The following data may be given by the supplier of the polymer modified bitumens in the product data
sheet:
— polymer dispersion (see EN 13632 [6]);
— solubility (see EN 12592 [7] using the appropriate solvent declared by the supplier);
— handling temperatures;
— minimum storage and pumping temperatures;
— storage conditions;
— maximum and minimum mixing temperatures; for comparison purposes, EN 13302 or EN 13702
should be used;
— density (see EN 15326).
6 Assessment and verification of constancy of performance — AVCP
6.1 General
The compliance of polymer modified bitumens with the requirements of this document and with the
performances declared by the manufacturer in the Declaration of Performance (DoP) shall be
demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
NOTE The information from AVCP can be available for audit as detailed in the Quality Plan.
6.2 Type testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, classified without further
testing (CWFT) and conventionally accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family.
NOTE 1 Products can be grouped in different families for different characteristics.
NOTE 2 Reference to the assessment method standards can be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or changed polymer modified bitumen (unless a
member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the stated
properties);
— or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the
polymer modified bitumen design, in the raw material or in the supplier of the components, or in
the method of production (subject to the definition of a family), which would affect significantly one
or more of the characteristics.
NOTE 3 The producer defines in his FPC documentation the conditions which define a significant change.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the polymer modified bitumen manufacturer to ensure that the polymer
modified bitumen as a whole is correctly manufactured and its component products have the declared
performance values.
6.2.2 Test samples, testing and compliance criteria
Sampling shall be carried out in accordance with EN 58 and EN 12594.
6.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the
polymer modified bitumen to which they relate.
6.2.4 Shared other party results
A manufacturer may use the results of the product type determination obtained by someone else (e.g.
by another manufacturer, as a common service to manufacturers, or by a product developer), to justify
his own declaration of performance regarding a product that is manufactured according to the same
design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same
kind, provided that:
— the results are known to be valid for products with the same essential characteristics relevant for
the product performance;
— in addition to any information essential for confirming that the product has such same
performances related to specific essential characteristics, the other party who has carried out the
determination of the product type concerned or has had it carried out, has expressly accepted to
transmit to the manufacturer the results and the test report to be used for the latter’s product type
determination, as well as information regarding production facilities and the production control
process that can be taken into account for FPC;
— the manufacturer using other party results accepts to remain responsible for the product having
the declared performances and he also:
— ensures that the product has the same characteristics relevant for performance as the one that
has been subjected to the determination of the product type, and that there are no significant
differences with regard to production facilities and the production control process compared
to that used for the product that was subjected to the determination of the product type, and
— keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same
design and with raw materials, constituents and manufacturing methods of the same kind.
6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products
placed on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the
use of the results to control raw and other incoming materials or components, equipment, the
production process and the product.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures.
This factory production control system documentation shall ensure a common understanding of the
evaluation of the constancy of performance and enable the achievement of the required product
performances and the effective operation of the production control system to be checked. Factory
production control therefore brings together operational techniques and all measures allowing
maintenance and control of the compliance of the product with the declared performances of the
essential characteristics.
In case the manufacturer has used shared product type results, the FPC shall also include the
appropriate documentation as described in 6.2.4.
6.3.2 Requirements
6.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line
with the content of this product standard. Tasks and responsibilities in the production control
organization shall be documented and this documentation shall be kept up-to-date.
The responsibility, authority and the relationship between personnel that manages, performs or verifies
work affecting product constancy, shall be defined. This applies in particular to personnel that need to
initiate actions preventing product non-constancies from occurring, actions in case of non-constancies
and to identify and register product constancy problems.
Personnel performing work affecting the constancy of performance of the product shall be competent
on the basis of appropriate education, training, skills and experience for which records shall be
maintained.
In each factory the manufacturer may delegate the action to a person having the necessary authority to:
— identify procedures to demonstrate constancy of performance of the product at appropriate stages;
— identify and record any instance of non-constancy;
— identify procedures to correct instances of non-constancy.
The manufacturer shall draw up and keep up-to-date documents defining the factory production
control. The manufacturer's documentation and procedures should be appropriate to the product and
manufacturing process. The FPC system should achieve an appropriate level of confidence in the
constancy of performance of the product. This involves:
a) the preparation of documented procedures and instructions relating to factory production control
operations, in accordance with the requirements of the technical specification to which reference is
made;
b) the effective implementation of these procedures and instructions;
c) the recording of these operations and their results;
d) the use of these results to correct any deviations, repair the effects of such deviations, treat any
resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-
constancy of performance.
Where subcontracting takes place, the manufacturer shall retain the overall control of the product and
ensure that he receives all the information that is necessary to fulfil his responsibilities according to this
document.
If the manufacturer has Part of the product designed, manufactured, assembled, packed, processed
and/or labelled by subcontracting, the FPC of the subcontractor may be taken into account, where
appropriate for the product in question.
The manufacturer who subcontracts all of his activities may in no circumstances pass the above
responsibilities on to a subcontractor.
NOTE Manufacturers having an FPC system, which complies with EN ISO 9001 standard and which addresses
the provisions of the present document are considered as satisfying the FPC requirements of the Regulation (EU)
No 305/2011.
6.3.2.2 Equipment
6.3.2.2.1 Testing
