16、91:2009 EN 12591:2009 (E) 3 Foreword This document (EN 12591:2009) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text
17、or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. 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 responsibl
18、e for identifying any or all such patent rights. This document supersedes EN 12591:1999. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Construction Product Directive (89/106/E
19、EC). For relationship with EU Construction Product Directive (89/106/EEC), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Sta

The properties of “adhesion“ and “setting ability“ are indicated by tests used on either the finished asphalt mixtur
23、es 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 European Standard still consists of specifications based upon traditional test methods. Work programs are being undertaken to evaluate alternative proper
24、ties and test methods in order to develop new specifications that are more directly performance-related. The progress of those work programmes are reported in CEN/TR 15352 17, and the results will be considered for future revisions of this European Standard. BS EN 12591:2009 EN 12591:2009 (E) 5 1 Sc
25、ope This European Standard provides a framework for specifying a range of properties and relevant test methods for bitumens, which are suitable for use in the construction and maintenance of roads, airfields and other paved areas, together with requirements for evaluation of conformity. This Europea
26、n Standard does not directly address cohesion, adhesion and setting ability (see Introduction). NOTE Although industrial bitumens are specified according to EN 13305, it should be underlined that paving grade bitumens, specified according to this European Standard, can also be used for industrial ap

34、N 12594. 5 Requirements and test methods 5.1 General European product standards cover a large variety of road materials for different applications, to accommodate local traffic loads and climatic conditions. This European Standard therefore also covers a large range of bitumens to facilitate the pro
35、duction and application of the designed paving. The variety of production techniques and applications makes it more practical to split bitumens into three separate tables. The requirements for the properties for a specific grade shall be selected from Table 1A, Table 1B, Table 2A, Table 2B, Table 3A
36、 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 properties in Table 1A, Table 2A and Table 3A shall be specified for all paving grade bitumens. They are associated with regulatory or HSE requireme
37、nts. The properties in Table 1B, Table 2B and Table 3B are required to meet specific regional conditions. They are associated with regulatory or other regional requirements. Two severity levels for resistance to hardening are stated as alternatives as, under specific conditions, a larger increase in
38、 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 with requirements for Fraass breaking point or penetration index (Ip) or both. NOTE For complementary information on grade selection, see Annex
39、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 1A 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 sha
40、ll conform to the limits specified. The grades are designated by the nominal penetration or viscosity ranges as appropriate. 5.2.2 Consistency at intermediate service temperature Consistency at intermediate service temperature shall conform to the requirements for penetration value in Table 1A or Ta
41、ble 2A. 5.2.3 Consistency at elevated service temperature Consistency at elevated service temperature shall conform to the requirements for softening point in Table 1A (penetration graded), softening point or dynamic viscosity in Table 2A (penetration graded), or kinematic viscosity in Table 3A (kin
42、ematic viscosity graded). BS EN 12591:2009 EN 12591:2009 (E) 7 5.2.4 Brittleness at low service temperature Brittleness at low service temperature may be required to meet specific regional conditions in countries susceptible to extreme cold. Where required, paving grade bitumens shall conform to the
43、 requirements for Fraass breaking point in Table 1B or Table 2B. 5.2.5 Temperature dependence of consistency Temperature dependence of consistency may be required to meet specific regional conditions. Where required, paving grade bitumens shall conform to the requirement for dynamic viscosity or pen
44、etration index (Ip) or both in Table 1B. 5.2.6 Durability Resistance to hardening Durability is demonstrated by compliance with the required surrogate characteristics of “Resistance to hardening”, defined in Table 1A, Table 2A or Table 3B. Resistance to hardening shall be tested according to the Rol
45、ling 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 the 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 requirem
46、ents for the density of paving grade bitumens are not given in this document, density shall be determined, when necessary, in accordance with EN 15326. 5.2.7.2 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-Marten
47、s 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 investigate possible contamination but is likely to give lower values than the Cleveland open cup method. 5.3 Release of dangerous regulated subs
48、tances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. 5.4 Precision The test methods referred to in
49、 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.
