23、c) Durability of consistency. The properties of “adhesion“ and “setting ability“ are indicated by tests used on either the finished asphalt mixtures or on aggregate-bitumen combinations, i.e. EN 126971, EN 1269711, EN 1269712, EN 12697 26 1 to 4, rather than tests on the bitumen itself. This Europea

24、n Standard still consists of specifications based upon traditional test methods. Work programs are being undertaken to evaluate alternative properties and test methods in order to develop new specifications that are more directly performance-related. The progress of those work programmes are reporte

25、d in CEN/TR 15352 17, and the results will be considered for future revisions of this European Standard. BS EN 12591:2009EN 12591:2009 (E) 5 1 Scope This European Standard provides a framework for specifying a range of properties and relevant test methods for bitumens, which are suitable for use in

26、the construction and maintenance of roads, airfields and other paved areas, together with requirements for evaluation of conformity. This European Standard does not directly address cohesion, adhesion and setting ability (see Introduction). NOTE Although industrial bitumens are specified according t

27、o EN 13305, it should be underlined that paving grade bitumens, specified according to this European Standard, can also be used for industrial applications. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、ucts 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 applications, to accomm

35、odate 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. The variety of production techniques and applications makes it more practical to split bitumens into three se

36、parate tables. The requirements for the properties for a specific grade shall be selected from Table 1A, Table 1B, Table 2A, Table 2B, Table 3A and Table 3B by choosing a column representing the specified values or ranges. There is a subdivision of properties into two groups in the tables. The prope

37、rties in Table 1A, Table 2A and Table 3A shall be specified for all paving grade bitumens. They are associated with regulatory or HSE requirements. The properties in Table 1B, Table 2B and Table 3B are required to meet specific regional conditions. They are associated with regulatory or other region

38、al requirements. Two severity levels for resistance to hardening are stated as alternatives as, under specific conditions, a larger increase in softening point after Rolling Thin Film Oven Test (RTFOT) may be allowed (i.e. Severity level 2) without detrimental effect if this increase is associated w

39、ith requirements for Fraass breaking point or penetration index (Ip) or both. NOTE For complementary information on grade selection, see Annex B. 5.2 Properties and related test methods 5.2.1 General The properties of paving grade bitumens and related test methods shall be in accordance with Table 1

40、A and Table1B, or Table 2A and Table 2B or Table 3A and Table 3B. When tested by the methods given in the Tables, the various paving grades shall conform to the limits specified. The grades are designated by the nominal penetration or viscosity ranges as appropriate. 5.2.2 Consistency at intermediat

41、e service temperature Consistency at intermediate service temperature shall conform to the requirements for penetration value in Table 1A or Table 2A. 5.2.3 Consistency at elevated service temperature Consistency at elevated service temperature shall conform to the requirements for softening point i

42、n Table 1A (penetration graded), softening point or dynamic viscosity in Table 2A (penetration graded), or kinematic viscosity in Table 3A (kinematic viscosity graded).

43、ired to meet specific regional conditions in countries susceptible to extreme cold. Where required, paving grade bitumens shall conform to the requirements for Fraass breaking point in Table 1B or Table 2B. 5.2.5 Temperature dependence of consistency Temperature dependence of consistency may be requ

44、ired to meet specific regional conditions. Where required, paving grade bitumens shall conform to the requirement for dynamic viscosity or penetration index (Ip) or both in Table 1B. 5.2.6 Durability Resistance to hardening Durability is demonstrated by compliance with the required surrogate charact

45、eristics of “Resistance to hardening”, defined in Table 1A, Table 2A or Table 3B. Resistance to hardening shall be tested according to the Rolling Thin Film Oven Test (RTFOT) in accordance with EN 12607-1 for binders from Table 1A and Table 2A. Resistance to hardening shall be tested according to th

46、e Thin Film Oven Test (TFOT) in accordance with EN 12607-2 for binders from Table 3A. 5.2.7 Other properties 5.2.7.1 Density Although requirements for the density of paving grade bitumens are not given in this document, density shall be determined, when necessary, in accordance with EN 15326. 5.2.7.

47、2 Flash point Flash point shall be determined by the Cleveland open cup method in EN ISO 2592 for binders in Table 1A and by the Pensky-Martens closed cup method, EN ISO 2719, for binders in Table 2A and Table 3A. NOTE For bitumens in Table 1A, the Pensky-Martens closed cup method may be used to inv

48、estigate possible contamination but is likely to give lower values than the Cleveland open cup method. 5.3 Release of dangerous regulated substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standa

49、rd for the material or permitted in the national regulations of the member state of destination. 5.4 Precision The test methods referred to in this document include precision statements when available. In cases of uncertainty, the procedures described in EN ISO 4259 for interpretation of the results based on test method precision shall be used.
