14、010-11 PageEN 13702:2010 (E) 3 Foreword This document (EN 13702:2010) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR/BNP. This European Standard shall be given the status of a national standard, either by publication of an identica
15、l text or by endorsement, at the latest by November 2010, and conflicting national standards shall be withdrawn at the latest by November 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held r
16、esponsible for identifying any or all such patent rights. This document supersedes EN 13702-1:2003. This document was formerly known as EN 13702 Part 1. As Part 2 of this standard was merged with another standard into EN 13302, this standard was renumbered into EN 13702. According to the CEN/CENELEC
17、 Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
18、Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 13702:2010-11 EN 13702:2010 (E) 4 1 Scope This European Standard specifies a method for determining the dynamic viscosity of a modified bituminous binder o
19、ver a range of temperatures by means of a cone and plate viscometer. Although the method has been developed for modified binders, it is also suitable for other bituminous binders. NOTE Unlike penetration grade bitumen, polymer modified bitumens (PMBs) may not show a straight line on the Heukelom-Dia
20、gram. This implies that in order to obtain information about the temperature susceptibility of PMBs, viscosity should be measured at different temperatures. WARNING The use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to
21、 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. 2 Normative references The following referenced doc
22、uments are indispensable for the application of this document. For dated references, only the edition cited applies.

23、itumen and bituminous binders Preparation of test samples 3 Principle The sample is placed on a plate, a cone is pressed onto the sample and the system is brought to the test temperature. A stress is applied to the sample by rotation. The torque is measured from the applied shear rate and dynamic vi
24、scosity is calculated by: =(1) where is the shear rate expressed in s-1; is the stress expressed in Pa, calculated by: dMA= (2) where A is the cone factor expressed in m-3; Mdis the torque in expressed N m. NOTE The advantages of this method are the use of a very small sample and the speed of the me
25、thod, especially regarding thermal conditioning of the specimen. DIN EN 13702:2010-11 EN 13702:2010 (E) 5 4 Apparatus Cone and plate viscometer, with the following minimum capabilities: range of shear rate: 5 x 10-2s-1to 5 x 102s-1; range of viscosity: 5 x 10-2Pa s to 105Pa s; range of temperature:
26、60 C to 150 C. The sample temperature shall be maintained within 0,5 C up to 100 C and within 1,0 C above 100 C. 5 Sampling Take the sample in accordance with EN 58 and prepare the sample in accordance with EN 12594. 6 Procedure Select the appropriate size (diameter and angle) of cone to allow measu
27、rement at the selected shear rate. Place the sample on the plate and press the selected cone onto the sample. Remove any surplus sample and bring the system to the test temperature. Commence the first measurement at the lowest temperature: Temperature: (60 0,5) C; Shear rate: 5 x 10-2s-1. Check the
28、reading after a delay of 15 min when reaching the temperature and note the temperature, the cone size, the shear rate and the reading. Repeat the test and calculate the result as an average of two tests. Replace the specimen and increase the temperature to the next test temperature. Commence the sec
29、ond measurement: Temperature: (100 0,5) C; Shear rate: 5 x 101s-1. Replace the specimen and increase the temperature to the next test temperature. Commence the third measurement: Temperature: (150 1,0) C; Shear rate: 5 x 102s-1. It should be ensured that the complete specimen has reached the test te
30、mperature before starting the test. The sample should not contain any filler. NOTE In addition to these test temperatures and shear rates any other temperature and shear rate can be used. DIN EN 13702:2010-11 EN 13702:2010 (E) 6 7 Expression of results Record the results of the measurement of dynami
31、c viscosity with the corresponding shear rate and the test temperature. Express the viscosity values in Pa s as follows: (1,000 x 10x) Pa s. 8 Precision NOTE The following precision data are the best currently estimated and are proposed until results of further round robin tests are available. 8.1 R
32、epeatability The difference between two successive results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, differ by more than 5 % in only one case in
33、 twenty. 8.2 Reproducibility The difference between two single and independent results, obtained by different operators working in different laboratories on identical test material would, in the long run, in the normal and correct operation of the test method, differ by more than 15 % in only one ca
34、se in twenty. 9 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) temperature, shear rate and the result of the test (see Clause 7); d) diameter and angle of the cone; e) date of the test; f) any deviation, by agreement or otherwise, from the specified procedure.
