EN 13587-2010 pdf download.Bitumen and bituminous binders – Determination of the tensile properties of bituminous binders by the tensile test method.
This EN 13587 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 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.
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.

3 Terms and definitions
Far the purposes of this document, the following terms and definitions apply.
3.1
tensile force
force undergone by a specimen subjected to extension
NOTE The unit is expressed in Newton (N).
3.2
tensile stress
ratio of the tensile force per unit area of the original cross-section
5 Apparatus
Usual Laboratory equipment and glassware, together with the following:
5.1 Test machine, in accordance with ISO 5893.
5.1.1 The machine shall be capable of maintaining a constant speed of the moving element at the speed chosen for the test to an accuracy of within 2 % of the chosen speed.
5.1.2 The specimen attachment device (located on the stationary part and on the moving part) shall:
ensure sufficient clamping of the specimen heads throughout the entire test, to prevent slipping:
— not exert, on any part of the ends of the specimen, localized stresses liable to cause tearing or fracture of the specimen.
5.1.3 Appropriate facilities shall permit the following measurements to be made:
— tensile force applied on the specimen over the range 1 N to 500 N to an accuracy of ± 1 %;
— elongation of the specimen, either by following the movement of the attachment points or by means of an optical extensometer over the range 0 mm to not less than 250 mm to an accuracy of ± 1 mm.
5.1.4 Optical extensometer
If an optical extensometer is used its reflectory devices shall be positioned on the bituminous specimen as near as possible to the specimen heads.
The distance between the two reflectory devices is approximately 45 mm to 50 mm. The facilities used shall be recorded In the test report.
5.2 Temperature controlled chamber. capable of maintaining the specimen and the attactiment device at the specified temperature throughout the test to an accuracy of ± 0,5 C, provided with a means of checking the test temperature. The control thermometer shall be placed near the specimen.
5.3 Recording device, for force applied and elongation of the test specimen.
5.4 Measurement apparatus, capable of measuring the thickness of the test specimen to an accuracy of
±0.1 mm.
The reference length or initial length of the H2 specimens is Ko = A + 2G. Specimens of different geometry can be used (if the preparation of H2 specimens is too difficult or impossible) but should be In accordance with the reference standards (i.e. EN ISO 527 or ISO 5893); this should be mentioned explicitly in the test report. The results obtained from such specimens can be used only for comparison with a binder tested under the same conditions.
6 Preparation and conservation of samples
Take the sample in accordance with EN 58. Prepare the sample in accordance with EN 12594. Pour surplus of material directly in the mould, let the specimens cool for about one hour to room temperature, and cut of the surplus with a heated spatula.
As an alternative for sample preparation the dumbbell-shaped specimen can be produced by cutting a thin sheet of the bituminous binder having the correct thickness by a model which will produce a specimen with the dimensions given in Table 1.
Reject specimens exhibiting defects. Keep specimens in their moulds and in a refrigerator at a maximum temperature of 10 °C and for a maximum of four days before the test.EN 13587-2010 pdf download.
