27、 elongation of 1333 %, corresponding to an elongation of 400 mm. 3.4 brittle break every rupture before 1333 % of elongation performing the force ductility test 4 Principle A tensile test is carried out either on: the bituminous binder, or the recovered binder in accordance with EN 13074, or the res
28、idual binder after distillation in accordance with EN 1431, or the aged binder in accordance with the EN 14895. NOTE 1 EN 13074 and EN 14895 are currently under revision, revised draft ENs are respectively numbered prEN 13074-1 and prEN 13074-2. A moulded test specimen is extended in ductilometer at
29、 the test temperature and at constant speed until fracture or an elongation of at least 1333 % (400 mm) is achieved. NOTE 2 The specimen is a symmetrical shaped block of bitumen (Figure 1). 5 Apparatus 5.1 Ductilometer The ductilometer consists of a traction device (5.1.1) and a water bath (5.1.2).
30、5.1.1 Traction device 5.1.1.1 The traction device shall be capable of maintaining a constant speed of the moving elements at (50 2,5) mm/min. 5.1.1.2 The specimen attachment device located at both ends of the specimen shall not exert on any part of the ends of specimen, localised stresses liable to
31、cause tearing or fracture of the specimen. 5.1.1.3 Appropriate facilities shall permit the following measurements to be made: a) tensile force exerted on the specimen over the range from 1 N to 300 N, to an accuracy of 0,1 N; b) elongation of the specimen, either by following the movement of the att
32、achment points or by means of an optical extensiometer over the range 1 mm to not less than 450 mm to an accuracy of 1 mm. 5.1.2 Water bath, temperature-controlled, capable of maintaining the specimen and the attachment device at the specified temperature throughout the test to an accuracy of 0,5 C,
33、 provided with a means of checking the test temperature. When the test is performed at 0C (see Clause 7) or at a lower temperature, the liquid bath shall be water added with 15 % mass fraction of ethanol.

The ends f
35、or the moulds are known as clips and are similar to those specified in EN 13398. The inner radius of the clips should be of (15,5 0,1) mm, the opening width (20,0 0,2) mm and the inner length of the clips should be (22,8 0,2) mm. While testing, both clips of a mould shall be kept in place by two dia
36、metrically opposed sliding pins. Whilst the test specimens are being cast and kept on test temperature, the moulds shall be placed on a base plate, also made of metal, and they shall be pressed together with a knurled screw.

Coat the base plate and the interior side of the lateral walls
38、 of the side parts of the mould with a release agent consisting of one part by mass of dextrine (or mineral talc) and one part by mass of glycerine, or with silicone. Assemble the parts of the three moulds and place them on the base plate. Press both halves of the moulds together using the knurled s
39、crew. BS EN 13589:2008EN 13589:2008 (E) Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 19/11/2008 08:17, Uncontrolled Copy, (c) BSI7 Add the amount of sample needed for three test specimen to a melting dish and heat it as described in EN 13398. Immediately fill the three moulds using a backw
40、ard and forward motion in the longitudinal direction of the mould, in order to give a uniform sample distribution in the mould, until a convex meniscus is obtained. Keep the moulded specimens for about 1 h at room temperature then remove the excess sample using a heated knife. Reject any specimens e
41、xhibiting defects. Place the moulded specimens in the water bath maintained at the test temperature for (90 10) min, before testing. Testing shall be carried out on the same day. 7 Procedure Run the test specimen by specimen. NOTE 1 If the traction and recording device allow the individual addressin
42、g of several specimen at once, more than one specimen may be tested at the same time. Once the level filled moulds have been kept at the test temperature for (90 10) min, remove the moulded specimen from the base plate, transfer the test specimen to the traction plates and remove the sides of mould.
43、 Then stretch the specimen at the usual test temperature, i.e. (5,0 0,5)C and at a speed of (50,0 2, 5) mm/min up to an elongation of 1 333 % (400 mm). Repeat any test in which a brittle break occurs. If the second specimen also breaks, raise the temperature by steps of 5 C until the test is complet
44、e without brittle break. As mentioned above, the test temperature is generally (5,0 0,5) C. However, in case of: soft bituminous binders, the test may be performed at a lower temperature, e. g. (0,0 C 0,5 C), and hard PMBs, the test should be performed at (10,0 0,5) C, or even at (15,0 0,5) C. NOTE
45、2 In general for hard PMB (i.e. PMB 10/30 63 and similar), no brittle break occurs at 10 C. If necessary the test should be run at 15 C. 8 Expression of results Calculate the result according to EN 13703. 9 Precision Since the result is calculated according to EN 13703, precision data from round rob
46、in test are indicated in EN 13703. 10 Test report The test report shall contain at least the following information: a) type and complete identification of the sample under test; b) reference to this European Standard; c) identity of the tester; d) results of the test (see Clause 8); BS EN 13589:2008
