32、and definitions given in EN 12597:2000 apply. The following abbreviation term is used in the specification tables of this document (see Table 1, Table 2 and Table 3): TBR for “To Be Reported“: this class shall mean that the manufacturer is invited, but not required, to provide information, regarding

33、 performance characteristics, with the product. NOTE The reported values (TBR) are intended to be used for future development of specifications. NR for “No Requirement“ may be used when there are no regulations or other regional requirements for the property in the territory of intended use. 4 Sampl

34、ing Samples of bulk products shall be taken as described in EN 58. Test samples shall be taken from the laboratory samples, and prepared for testing, as described in EN 12594. 5 Requirements and test methods 5.1 General European product standards cover a large variety of road materials for different

35、 applications, to accommodate local traffic loads and climatic conditions. This European Standard therefore also covers a large range of bitumens to facilitate the production and application of the designed paving. This European Standard is a framework of specifications and classes for properties of

36、 polymer modified bitumens which are chosen from Table 1, Table 2 and Table 3. BS EN 14023:2010EN 14023:2010 (E) 7 There is a subdivision of properties into three groups in the tables. The properties in Table 1 shall be specified for all polymer modified bitumens. They are associated with regulatory

37、 or HSE requirements. The properties in Table 2 are required to meet specific regional conditions. They are associated with regulatory or other regional requirements. The properties in Table 3 are additional properties, which are non-mandated, but have been found useful in some countries to describe

38、 polymer modified bitumens. 5.2 Properties and related test methods 5.2.1 General The properties of, and the related test methods for polymer modified bitumens shall be selected from the classes given in Table 1 and Table 2. When tested by the methods given in a table, the various grades shall confo

39、rm to the limits specified in that table. In Table 3 further properties that have been considered useful for specifications are described. NOTE 1 Each country will then have a particular selection of specifications, which, if regulated, are covered in Tables 1 and 2 and which, if commonly used by in

40、dustry, are covered in Table 3. It is useful for each country to publish in a national guidance document for each application, their requirements for polymer modified bitumens from Table 1, Table 2 and Table 3. The appropriate class for each technical requirement or application is selected in turn a

41、nd the selection of classes should be made from past experience of successful use, on a regional basis, in order to avoid unworkable combinations. NOTE 2 In order to assist in using the tables, an example has been provided in Annex A. 5.2.2 Consistency at intermediate service temperatures Consistenc

42、y at intermediate service temperature for polymer modified bitumens shall comply with the requirements for penetration at 25 C in Table 1. The grades are designated by the nominal penetration range at 25 C. 5.2.3 Consistency at elevated service temperatures Consistency at elevated service temperatur

43、e for polymer modified bitumens shall comply with the requirements for softening point as indicated in Table 1. Polymer modified bitumens are supplied for a variety of end uses in various climatic conditions; consequently the specifications include a wide range of softening point values. NOTE The va

44、rious softening point limits are included so as not to prevent some traditional methods used to evaluate the suitability of modified bitumens in the different European climatic conditions (for more information refer to national guidance documents). As the grading system is based on the consistency a

45、t intermediate and elevated service temperatures, values shall be given for these characteristics. 5.2.4 Brittleness at low service temperature Brittleness at low service temperature may be required to meet specific regional conditions. Where required, polymer modified bitumens shall conform to the

46、requirements for Fraass breaking point in Table 2. For some highly modified polymer modified bitumens, Fraass breaking point is not a suitable low temperature method and, in that case, low temperature elastic recovery at 10 C shall be used. 5.2.5 Cohesion The property of cohesion is included as a me

47、ans of differentiating polymer modified bitumens from paving grade bitumens. Three different test methods are included in Table 1: force ductility, tensile test and Vialit pendulum. These reflect the different characteristics that can occur with polymer modified bitumens and are not considered to be

48、 equivalent. It is intended that the most appropriate cohesion test method shall be used in each case, at the discretion of the supplier. The manufacturer shall state the test method used. BS EN 14023:2010EN 14023:2010 (E) 8 One cohesion method shall be chosen based on end application. Vialit cohesi

49、on (EN 13588) shall only be used for surface dressing binders. 5.2.6 Durability Resistance to hardening Resistance to hardening shall be tested after conditioning in accordance with the Rolling Thin Film Oven Test (RTFOT) (see EN 12607-1). The main test is the RTFOT at 163 C. For some highly viscous polymer modified bitumens where the viscosity is too high to provide a moving film it is not possible to carry out the RTFOT at the reference temperature of 163 C. In such cases the proced
