European foreword
This document (prEN 13587:2025) has been prepared by Technical Committee CEN/TC 336 “Bitumens and
bituminous binders”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13587:2016.
prEN 13587:2025 includes the following significant changes with respect to EN 13587:2016:
a) Clause 5, Apparatus: for the specimen attachment, the use of pneumatic clamping jaws has been
recommended (see 5.1.2);
b) Clause 6, Samples preparation and conservation: specimens are cooled down at room temperature
between 1 h and 24 h and then kept in a refrigerator for not more than 1 h before the test;
c) Clause 7, Procedure: the measurement of width B has been introduced, the duration of the holding time
of the specimen at the test temperature has been set to an interval of 1 h to 3 h and the requirement for a
waiting time of 5 min after temperature stabilization has been withdrawn;
d) Clause 8, Calculation: the result shall now be the average of three determinations for each parameter;
e) Clause 9, Expression of results: has been introduced requiring the cohesion energy results to be expressed
to two significant figures;
f) Clause 10, Precision: has been reworded;
g) Annex A, Cohesion specification criteria: keys have been added to Figures A.1 and A.2;
h) the document and its structure have been editorially reviewed.

1 Scope
This document specifies a method for determining the tensile properties of a bituminous binder, in particular
those of a polymer modified bitumen, by means of a tensile test.
NOTE 1 The tensile properties, more particularly the tensile stress, the elongation and energy, at the yield point and
on fracture, are customarily used as a criterion for assessing the quality of these materials.
NOTE 2 The test method described in EN 13589 [1] is an alternate test method to determine the tensile properties of
polymer modified bitumens.
WARNING — The use of this document can involve hazardous materials, operations and equipment. This
document does not purport to address all of the safety problems associated with its use. It is the responsibility
of the user of this document to establish appropriate safety and health practices and to determine the
applicability of regulatory limitations prior to use.

3.1
tensile force
F
force undergone by a specimen subjected to extension
Note 1 to entry: Tensile force is expressed in Newton (N).
3.2
Elongation
L
increase in length of a specimen
prEN 13587:2026 (E)
Note 1 to entry: Elongation is expressed in metres (m).
Note 2 to entry: Elongation can also be expressed in percentage (%) of the initial length. It is then calculated as [(new
length – initial length)/initial length] × 100.

4 Principle
A specimen, held by its ends between two jaws, is extended in a chamber (5.2), regulated at the test
temperature, at a constant speed until a given elongation or fracture is achieved. In general, the stress and the
elongation are noted at the flowing thresholds: at an elongation of 400 % and at breaking.
The deformation energy, E , is determined from the recordings of the tensile curve (see Figures A.1) obtained,
i
in accordance with the procedure described in Clause 7, by calculating the area delimited by:
— the abscissa axes corresponding to elongations;
— the recorded curve (force versus elongation);
— a parallel to the ordinate axis which passes by a given elongation or the breaking point (see Figure A.2).
*
The cohesion energy, E , is obtained as the quotient of the deformation energy at 400 % elongation (250 mm
i
for H2 type specimen final length) and the initial cross section of the test specimen.
