Bitumen and bituminous binders - Specifications for hard paving grade bitumens
This document provides a framework for specifying the properties and relevant test methods for hard paving grade bitumens which are suitable for use in the construction and maintenance of roads, airfields and other paved areas. This framework covers three essential characteristics according to the mandate M/124: EU Construction Products Directive 89/106/EEC : - "Consistency at intermediate service temperature"; - "Consistency at elevated service temperature"; - "Durability" of the above. This document is closely related to EN 12591. This introduction gives information on the basis for selection of the grades defined in this document, the status of certain 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 conditions 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 having very high modulus values. This standard can be read in conjunction with National Guidance Documents, where they exist, which have the opportunity to identify the appropriate grade in the territory of use.

EN 13924:2006 (E) 4 Introduction This document is closely related to EN 12591 [1]. This introduction gives information on the basis for selection of the grades defined in this document, the status of certain of the properties and test methods, and proposed development of this document. The general principle adopted in the development of EN 12591 [1] 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 conditions encountered, in all the Member States. This document extends the range of grades specified in EN 12591 [1], following the wider use of materials for road construction and maintenance having very high modulus values. This standard can be read in conjunction with National Guidance Documents, where they exist, which have the opportunity to identify the appropriate grade in the territory of use. This document has been based on the regional requirements identified when the process started. It is a first step 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 revision of this document. The progress of those work programmes are reported in CEN/TR 15352 [2], and the results will be considered for future revisions of this European Standard. For paving grade bitumen the testing of the three essential characteristics, according to the mandate 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 [3] to [6]), rather than tests on the bitumen itself. The introduction of technical classes of convenience (see Table 1) enables the selection of the most suitable specification for the bitumen taking account of local conditions of climate and use. Hard paving grade bitumens are designated by the penetration range at 25 °C, e.g. 10/20 pen or 15/25 pen (see Table 1). Table B.1 (Annex B) lists informative properties which suppliers of hard paving grades of bitumen are encouraged to produce as “Supplier Declared Values”. It is hoped that the data so provided will form the basis for developing performance-related specifications in the future.

SIST EN 13924:2006
EN 13924:2006 (E) 6 4 Sampling 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 Properties and related test methods 5.1.1 General The properties 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 technical 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), 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 characteristics 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 supplier's declared value or range 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 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 hard 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 comply 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 range, 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 hardening Durability shall be demonstrated by compliance with the required surrogate characteristics of Table 1. SIST EN 13924:2006
EN 13924:2006 (E) 7 Resistance to hardening shall be tested according to the Rolling Thin Film Oven Test (RTFOT) (EN 12607-1). NOTE 1
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. 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 properties 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 will 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 possible 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 statement 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.
