17、reword This document (EN 13924-2:2014) 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 or by endorsement, at the la
18、test by September 2014 and conflicting national standards shall be withdrawn at the latest by December 2015. 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 responsible for identifying any or a
19、ll such patent rights. 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 Directive(s). For relationship with EU Directive(s), see informative Annex ZA which is an integral part of
20、 this document. This European Standard is part of a family of European Standards for bitumen as follows: NOTE Industrial applications are not covered by mandate M/124. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to impl
21、ement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania

This introduction gives information on the basis for selection of the grades defined in this document, the status of cer
23、tain of the properties and test methods, and proposed development of this document. The general principle adopted in the development of EN 12591 was to provide a range of grades suitable for the manufacture of the materials for road construction and maintenance used, and the climatic and traffic con
24、ditions encountered, in all the Member States. This document extends the range of grades specified in EN 12591, following the wider use of materials for road construction and maintenance. This document has been based on the regional requirements identified when the process started. It is a first ste
25、p in harmonising the so-called “empirical“ specifications and it is intended to evaluate alternative properties and test methods to develop new specifications that are more directly performance-related. To this end, work programmes are being undertaken and the results will be considered for a future
26、 revision of this document. The progress of those work programmes are reported in CEN/TR 15352 1, and the results will be considered for future revisions of this European Standard. For multigrade paving grade bitumens (MG), the testing of the five essential characteristics, according to the mandate
27、M/124, also gives an indication that its intrinsic cohesive properties are adequate for its normal use. The properties of “adhesion“ and “setting ability“ are indicated by tests used on the finished asphalt mixtures, EN 12697-1, EN 12697-11, EN 12697-12, EN 12697-26 (respectively 2 to 5), rather tha
28、n tests on the bitumen itself. In certain acid modified binders the structure may change when mixed with aggregate. Table B.1 lists informative properties which suppliers of multigrade bitumens are encouraged to produce as “Supplier Declared Values”. It is hoped that the data so provided will form t
29、he basis for developing performance-related specifications in the future. BS EN 13924-2:2014EN 13924-2:2014 (E) 5 1 Scope This document provides a framework for specifying the properties and relevant test methods for multigrade paving grade bitumens which are suitable for use in the construction and
30、 maintenance of roads, airfields and other paved areas, together with information for attestation and verification of constancy of performance. Multigrade paving grade bitumens are designated in EN 12597:2000 as special bitumens for road applications having a positive penetration index (Ip). This do
31、cument does not directly address cohesion, adhesion and settling ability, (see Clause Introduction). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、tumens are designated by stating MG and the nominal penetration range at 25 C, followed by the softening point range (see Table 1), e.g. “MG 20/30-64/74“ BS EN 13924-2:2014EN 13924-2:2014 (E) 6 4 Sampling Samples of bulk products shall be taken as described in EN 58. Test samples shall be taken from
38、 the laboratory samples, and prepared for testing, as described in EN 12594. 5 Requirements and test methods 5.1 General The requirements for the properties for a specific grade shall be selected from the classes given in Tables 1 and 2. The properties in Table 1 shall be specified for all multigrad
39、e paving grade bitumens. They are associated with regulatory or Health Safety and Environmental requirements. The properties in Table 2 are required to meet specific regional conditions. They are associated with regulatory or other regional requirements. When tested by the methods given in the table
40、s, the various multigrade paving grade bitumens shall conform to the limits specified by classes in these tables. NOTE The TBR class has been included to facilitate selection in countries which merely wish to record a suppliers range for a particular requirement. It should not be considered as a “Cl
41、ass“ for the purpose of regulatory marking. These values can be used as a basis for the development of future technical specifications. The selection of classes should be made from past experience to avoid unworkable combinations. 5.2 Properties and related test methods 5.2.1 General For specifying
42、multigrade paving grade bitumens the appropriate class for each technical requirement is selected in turn. Different classes may be selected for different properties. 5.2.2 Consistency at intermediate service temperature Consistency at intermediate service temperature for these multigrade paving gra
43、de bitumens shall comply with the requirements for penetration at 25 C in Table 1. 5.2.3 Consistency at elevated service temperature Consistency at elevated service temperature for these multigrade paving grade bitumens shall comply with the requirements for softening point Ring and Ball in Table 1.
44、 5.2.4 Temperature dependence of consistency Temperature dependence of consistency shall comply with the requirements for penetration index (Ip) in Table 1. Where required, multigrade paving grade bitumens shall comply also with the requirement for dynamic viscosity in Table 2. The penetration index
45、 shall be calculated in accordance with Annex A. 5.2.5 Brittleness at low service temperature Brittleness at low service temperature may be required to meet specific regional conditions. Where required, multigrade paving grade bitumens shall conform to the requirements for Fraass breaking point in T

The choice of class may depend upon the intended use of the product. 5.2.7 Temperature dependency of mixing Where required, multigrade paving grade bitumens
48、shall comply also with the requirement for kinematic viscosity in Table 2. 5.2.8 Other properties 5.2.8.1 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 8) can be used to investigate possible con
