24、) 4 1 Scope This European Standard 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 yie

25、ld 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 wi

26、th 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in t

27、his document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 58, Bitumen and bituminous binders Sampling bituminous binders EN 12594, Bitumen

29、ment, the following terms and definitions apply. 3.1 tensile force force undergone by a specimen subjected to extension, expressed in Newton (N) 3.2 elongation increase in length of a specimen, expressed in metres Note 1 to entry: Elongation is also expressed in % from the initial length. It is calc

30、ulated as (new length initial length)/initial length null 100. 3.3 brittle break rupture happening at the beginning of the test before the flowing threshold when the stress-strain curve is still linear 3.4 flow threshold first maximum of the stress-strain curve DIN EN 13587:2017-02EN 13587:2016 (E)

31、5 3.5 deformation energy Eienergy in joules (J) supplied by test pieces, until displacement, i, of the moving element 3.6 cohesion energy E*iquotient of deformation energy, Ei(in joules) and the initial cross section of the test pieces (in square centimetres) 4 Principle A specimen, held by its ends

32、 between two jaws, is extended in a chamber, regulated at the test temperature, at constant speed until a given elongation or fracture is achieved. In general, stress and elongation are noted at the flowing threshold, at an elongation of 400 % and at breaking. The deformation energy (Ei) is determin

33、ed from the recordings of the tensile curves (see Figure A.1) obtained according to chapter 7, by calculating the area delimited by: the abscissa axes corresponding to elongations; the recorded curve (force versus elongation); a parallel to the ordinates axis which passes by a given elongation or th

34、e breaking point (see Figure A.2). Cohesion energy (E*i) is obtained as a quotient of the deformation energy at 400 % elongation (250 mm for H2 type specimen final length) and the initial cross-area of the test specimens. 5 Apparatus Usual laboratory equipment and glassware, together with the follow

35、ing: 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

36、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 The equipment shall permit the following measure

37、ments 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.

38、DIN EN 13587:2017-02EN 13587:2016 (E) 6 5.1.4 Optical extensometer. If an optical extensometer is used its reflector devices shall be positioned on the bituminous specimen as near as possible to the specimen heads. The distance between the two reflector devices is approximately 45 mm to 50 mm. The t

39、ype of extensometer used shall be recorded in the test report. 5.2 Temperature controlled chamber, capable of maintaining the specimen and the attachment 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 contr

40、ol 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. 5.5 Moulds allowing moulding of specimens (see Figure 1), e.g. m

41、ade in silicone elastomer.

Specim

42、ens 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. the EN ISO 527- series or ISO 5893); this should be mentioned explicitly in the test report. The results obtained from such specime

43、ns can be used only for comparison with a binder tested under the same conditions. DIN EN 13587:2017-02 EN 13587:2016 (E) 7 6 Preparation and conservation of samples Take the sample in accordance with EN 58. Prepare the sample in accordance with EN 12594. Pour a surplus of material directly in the m

44、ould and allow the specimens to cool to room temperature for about one hour. Trim of the excess material 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 mo

45、del 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 24 h before the test. 7 Procedure Measure the thickness, D, of the specimen with an

46、accuracy of 0,1 mm. Set the apparatus to the test temperature. Maintain the chamber containing the specimen at the test temperature for at least one hour. Attach the specimen in the attachment device in accordance with the EN ISO 527- series with a distance between the jaws, K0, of 50 mm 0,5 mm for

47、specimens of the H2 type. Wait five minutes after stabilization of the test temperature 0,5 C and start the test. Record the force and elongation for the test specimen, as indicated in Clause 8. Repeat any test in which a brittle break occurs (break before the flowing threshold). After three brittle

48、 breaks, in the thin part of the specimen, stop the test and record the binder as “brittle”. General values of test temperature and test speed are the following: Temperature: 20 C, 15 C, 10 C, 5 C, 0 C, 5 C, 10 C, 15 C, 20 C. Speed: 1 mm/min, 10 mm/min, 50 mm/min, 100 mm/min, 500 mm/min. 8 Calculati

49、on and expression of results The deformation Energy, Ei, is calculated as the definite integral of force as a function of elongation, see Formula (1). The final results are expressed as cohesion energy, E*i, in joules per square centimetre. Cohesion is calculated dividing the deformation energy, Ei, by the initial cross section of the test specimen expressed in square centimetres. The
