The UK participation in its preparation was entrusted by Technical Committee B/510, Road materials, to Subcommittee B/510/19, Bitumen and related products. A list of organizations re

EN 13924:2006 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/124, Road Construction Products, given under the EU Construction Products Directi
5、ve (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 13924:2006 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. EN 139
6、24:2006 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 13924:2006 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine
7、-month period during which any required changes to national regulations are to be made, followed by a further nominal twelve-month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn or revised. In the UK, the corresponding
8、national standard is: BS 3690-1:1989, Bitumens for building and civil engineering Part 1: Specification for bitumens for roads and other paved areas and based on this nominal transition period of twenty-one months, BS 3690-1:1989 will be withdrawn in, or revised by, February 2008.

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 Properties and related test methods 5.1.1 General The properti
31、es of and related test methods for hard paving grade bitumens shall be in accordance with Table 1. When tested by the methods given in the tables, the various paving grades shall conform to the limits specified by classes in that table. NOTE 1 For specifying bitumen the appropriate class for each te
32、chnical requirement is selected in turn, different classes may be selected for different properties. The selection of classes should be made from past experience to avoid unworkable combinations, also see in Table 1, Table footnote f. NOTE 2 Table 1 includes a “No Performance Determined“ class (NPD)
33、, a “No Requirement” class (NR) and a “To Be Reported“ class (TBR). The NPD class has been included to accommodate countries where the characteristic, for a given intended use, is not subject to regulatory requirements. (See Annex ZA for further information). The NR class has been included for chara
34、cteristics that are not mentioned in Table ZA.1 (i.e. not required for the purpose of regulatory marking), where there is no requirement to specify or declare a value. The TBR class has been included to facilitate selection in countries which merely wish to record a suppliers declared value or range
35、 for a particular requirement. It should not be considered as a Class for the purpose of regulatory marking. These values can be used as a basis for the development of future technical specifications. NOTE 3 Each country is anticipated to have a specific selection of specifications, which, more than
36、 likely, will be different, and each country could publish the table of its applicable specifications in a national guide to determine the appropriate specification from this document. 5.1.2 Consistency at intermediate service temperatures Consistency at intermediate service temperature for these ha
37、rd paving grade 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. 5.1.3 Consistency at elevated service temperatures Consistency at elevated service temperature for these hard paving bitumens shall comp
38、ly with the requirements for softening point Ring and Ball and, if selected, viscosity as indicated in Table 1. Hard paving grade bitumens are supplied for a variety of end uses, and thus the specifications include a wide range of softening point Ring and Ball values. A restricted softening point ra
39、nge, of 5 C about a mid-point, shall be declared by the supplier; the overall range shall be within the range in the tables. NOTE The properties and related test methods, given in Table 1, provide for different climatic, traffic and other conditions across Europe. 5.1.4 Durability Resistance to hard
40、ening Durability shall be demonstrated by compliance with the required surrogate characteristics of Table 1. EN 13924:2006 (E) 7 If the supplier wishes to declare the penetration index (for the purpose of regulatory marking), it shall be calculated in accordance with Annex A. 5.1.5 Informative prope
41、rties The specifications include a table of informative properties (Table B.1) based on new test methods that are under development. Suppliers of hard paving grade bitumens are encouraged to produce data from these measurements as “Supplier Declared Values”. It is hoped that the data so provided wil
42、l be of assistance in developing performance-related specifications in the future. 5.1.6 Other properties 5.1.6.1 Flash point Flash point shall be determined by the Cleveland open cup method in EN ISO 2592. NOTE The Pensky-Martens closed cup method (see EN ISO 2719 9) can be used to investigate poss
43、ible contamination but is likely to give lower values. 5.1.6.2 Density If the supplier wishes to declare the density of hard paving grade bitumens it shall be determined in accordance with prEN 15326. 5.2 Precision and dispute 5.2.1 The test methods referred to in this document include a precision s
44、tatement where 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. 5.2.2 The test methods referred to in this document shall be those used in cases of dispute. Resistance to hardening shall be tes
45、ted according to the Rolling Thin Film Oven Test (RTFOT) (EN 12607-1). NOTE Appropriate tests and classes, for measurements on material after the hardening procedure, are given in Table 1. The choice will depend upon the intended use of the product. EN 13924:2006 (E) 8 Table 1 - Specifications for h
