Bitumen and bituminous binders - Framework specification for polymer modified bitumens
This European Standard provides a framework for specifying the characteristics and relevant test methods for polymer modified bitumens which are suitable for use in the construction and maintenance of roads, airfields and other paved areas.
This framework covers the following characteristics:
- "Consistency at intermediate service temperature" (surrogate characteristic: penetration);
- "Consistency at elevated service temperature" (surrogate characteristic: softening point);
- "Cohesion";
- "Durability" of consistency.
The cohesion property has been included as a means of discriminating between polymer modified bitumens and other bituminous binders. The other essential requirements, "adhesion" and "setting ability" are indicated by tests carried out on the finished asphalt mixtures.
The introduction of classes of convenience in Tables 1 and 2 enables the selection of the most suitable specification for the bitumen taking account of local conditions of climate and use. The nomenclature of polymer modified bitumens comprises the penetration range and the minimum softening point (see example in Annex A).
Bitumen und bitumenhaltige Bindemittel - Rahmenwerk für die Spezifikation von polymermodifizierten Bitumen
Diese Europäische Norm legt einen Rahmen für die Spezifikation der Merkmale und maßgebenden Prüfverfahren für polymermodifizierte Bitumen fest, die für den Bau und die Instandhaltung von Straßen, Flugplätzen und sonstigen befestigten Flächen geeignet sind.
Dieser Rahmen deckt folgende Merkmale ab:
- "Konsistenz bei mittlerer Gebrauchstemperatur" (Ersatzmerkmal: Penetration);
- "Konsistenz bei erhöhter Gebrauchstemperatur" (Ersatzmerkmal: Erweichungspunkt);
- "Kohäsion";
- "Dauerhaftigkeit" der Konsistenz.
Die Eigenschaft Kohäsion wurde als Hilfsmittel zur Unterscheidung zwischen polymermodifizierten Bitumen und sonstigen bitumenhaltigen Bindemitteln aufgenommen. Die anderen wesentlichen Anforderungen, "Adhäsion" und "Härtungsvermögen" werden durch an fertigen Asphaltmischgütern durchzuführende Prüfungen angezeigt.
Durch die Einführung von Zweckmäßigkeitsklassen in den Tabellen 1 und 2 wird es ermöglicht, diejenige Spezifikation auszuwählen, die unter Berücksichtigung der örtlichen klimatischen Bedingungen und der Verwendungsbedingungen für das betreffende Bitumen am besten geeignet ist. Die Nomenklatur polymermodifizierter Bitumen umfasst den Bereich der Penetration und den Mindesterweichungspunkt (siehe Beispiel in Anhang A).
Bitumes et liants bitumineux - Cadre de spécifications des bitumes modifiés par des polymeres
Domaine d'application
La présente Norme européenne prescrit les caractéristiques des bitumes-polymeres employés pour la construction et l'entretien des chaussées, ainsi que les méthodes d'essai correspondantes. Les bitumes-polymeres concernés par la présente Norme européenne sont des bitumes modifiés par addition d'un ou de plusieurs polymeres organiques (voir EN 12597).
La présente Norme européenne est un systeme de classification. Celui-ci n'est pas obligatoirement en rapport avec le comportement fonctionnel des bitumes modifiés dans le cadre de leur application. Aussi, pour s'assurer que le bitume modifié répond bien aux exigences fonctionnelles désirées, il est nécessaire de vérifier son comportement au moyen d'une (de) méthode(s) d'essai appropriée(s) sur le matériau final lui-meme (par exemple l'enrobé ou l'enduit superficiel).
Il est prévu que les exigences générales contenues dans la présente Norme seront remplacées en temps utile par des caractéristiques fonctionnelles. A cette fin, des programmes de travail ont été engagés et leurs résultats seront pris en compte dans une révision ultérieure de la présente Norme.

EN 14023:2005 (E) 4 Introduction This European Standard is closely related to EN 12591 [1], Bitumen and bituminous binders – Specifications for paving grade bitumens. This introduction gives information on the basis for selection of the grades defined in this European Standard, the status of certain characteristics and test methods, and proposed development of this European Standard. 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 European Standard extends the range of grades specified in EN 12591 [1], following the wider use of modified binders for road construction and maintenance having improved performances. As with EN 12591 [1], it is compulsory for the full specification to be published in all EU and EATA countries. However, it is permitted for each country to define the most suitable grades and classes. This document has been based on the various national documents that were in existence when the process started. It is a first step in harmonising the so-called "empirical" specifications and it is intended to evaluate alternative characteristics 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. Annex B lists informative characteristics which producers of polymer modified bitumens are invited to supply to the client on a voluntary basis. It is hoped that the data so gathered will be of assistance in developing performance-related specifications in the future. SIST EN 14023:2005
EN 14023:2005 (E) 5 1 Scope This European Standard provides a framework for specifying the characteristics and relevant test methods for polymer modified bitumens which are suitable for use in the construction and maintenance of roads, airfields and other paved areas. This framework covers the following characteristics: "Consistency at intermediate service temperature" (surrogate characteristic: penetration); "Consistency at elevated service temperature" (surrogate characteristic: softening point); “Cohesion"; "Durability" of consistency. The cohesion property has been included as a means of discriminating between polymer modified bitumens and other bituminous binders. The other essential requirements, "adhesion" and "setting ability" are indicated by tests carried out on the finished asphalt mixtures. The introduction of classes of convenience in Tables 1 and 2 enables the selection of the most suitable specification for the bitumen taking account of local conditions of climate and use.

EN ISO 9001, Quality management systems – Requirements (ISO 9001:2000). 3 Symbols and abbreviations The following abbreviation terms are used in the specification tables of this document (see Tables 1 and 2): NPD for "No Performance Determined": this class has been included to accommodate countries where the characteristic, for a given intended use, is not subject to regulatory requirements (see ZA.1). TBR for "To Be Reported": this class shall mean that the manufacturer is invited, but not required, to provide information with the product. NOTE These reported values may be used for future specifications. 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 Characteristics and related test methods 5.1.1 General The values for the characteristics are given in Table 1 which is subdivided into eleven classes. The characteristics of, and the related test methods for polymer modified bitumens shall be selected from the classes given in Table 1. When tested by the methods given in a table, the various grades shall conform to the limits specified in that table.
In Table 2 further characteristics that have been considered useful for specifications are described. SIST EN 14023:2005
EN 14023:2005 (E) 7 If no data is given on the storage stability test (see EN 13399), information shall be given by the supplier regarding storage conditions for the polymer modified bitumen to avoid separation of the components. NOTE 1 Each country will then have a particular selection of specifications, which, if regulated, are covered in Table 1 and which, if commonly used by industry, are covered in Table 2. It is useful for each country to publish in a national guidance document for each application, their requirements for polymer modified bitumens from Table 1 and Table 2. The appropriate class for each technical requirement or application is selected in turn and the selection of classes should be made from past experience of successful use, on a regional basis, in order to avoid unworkable combinations. NOTE 2 In order to assist in using the tables, an example has been provided in Annex A. Class 1 TBR shall not be used for regulatory declaration and marking purposes. 5.1.2 Consistency at intermediate service temperatures Consistency at intermediate service temperature for polymer modified 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 polymer modified bitumens shall comply with the requirements for softening point as indicated in Table 1. Polymer modified bitumens are supplied for a variety of end uses in various climatic conditions, consequently the specifications include a wide range of softening point values. NOTE The various softening point limits are included so as not to prevent some traditional methods used to evaluate the suitability of modified bitumens in the different European climatic conditions (for more information refer to national guidance documents). As the grading system is based on the consistency at intermediate and elevated service temperatures, values shall be given for these characteristics. 5.1.4 Cohesion The property of cohesion is included as a means of differentiating polymer modified bitumens from paving grade bitumens. Three different test methods are included: force ductility, tensile test and Vialit pendulum. These reflect the different characteristics that can occur with polymer modified bitumens and are not considered to be equivalent. It is intended that the most appropriate cohesion test method shall be used in each case, at the discretion of the supplier. The manufacturer shall state the test method used. One cohesion method shall be chosen based on end application. Vialit cohesion (EN 13588) shall only be used for surface dressing binders. 5.1.5 Durability – Resistance to hardening Resistance to hardening shall be tested according to the Rolling Thin Film Oven Test (RTFOT) (see EN 12607-1). For a transitional period of three years from the date of availability of this document, resistance to hardening may also be tested using the Rotating Flask Test (RFT) (see EN 12607-3). For referee purposes, only RTFOT (see EN 12607-1) shall be used. NOTE 1 The transitional period is intended to provide new users with the opportunity to gather empirical data and experience of the RTFOT. NOTE 2 In order to assist in controlling rutting deformation and cracking of asphalt mixes, optional tests and classes, for measurements on material after the hardening procedure, are given in Tables 1 and 2. The choice will depend upon climatic conditions, traffic and local use. Resistance to hardening is not appropriate for surface dressing bitumens. SIST EN 14023:2005
EN 14023:2005 (E) 8 5.1.6 Informative characteristics The framework specifications include a table of informative characteristics (see Annex B) based on new test methods that are under development. Producers of polymer modified bitumens are invited to supply data from these measurements to the client on a voluntary basis. It is hoped that the data so gathered will be of assistance in developing performance-related specifications in the future. 5.1.7 Flash point Flash point shall be determined by the Cleveland open cup method in EN ISO 2592 for normal specification purposes. NOTE The Pensky-Martens closed cup method (see EN ISO 2719 [6]) can be used to investigate possible contamination but is likely to give lower values. For safety reasons, classes 0 and 1 shall not be used for flash point. 5.1.8 Density Although requirements for the density of polymer modified bitumens are not given in this document, density shall be determined, when necessary, in accordance with EN ISO 3838. 5.1.9 Plasticity range The plasticity range is the numerical difference between the softening point and Fraass breaking point. For example a polymer modified bitumen with a softening point of 75 °C and a Fraass breaking point of -18 °C would have a plasticity range of 93 °C. 5.2 Precision and dispute The test methods referred to in this document include precision statements where available. In cases of dispute, the procedures described in EN ISO 4259 for resolving the dispute, and interpretation of the results based on test method precision shall be used. . SIST EN 14023:2005
