Foreword
This document (prEN 12591:2005) has been prepared by Technical Committee CEN/TC 336 “Bitumen and
bituminous binders”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede 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/EEC).
For relationship with EU Construction Product Directive, see informative Annex ZA, which is an integral part of
this document.
In this European standard, Annex A is normative, Annex B is informative.
This European standard is part of a family of European Standards for bitumen as follows:

Introduction
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 considering the climatic and traffic
conditions encountered in all the Member States. It is compulsory for the full specification to be published in all
EU and EFTA countries. This European Standard has been revised to make it more harmonised than the
previous version, however it is permitted for each country to determine which of two severity levels to use and
which of the optional additional properties to adopt. The decision should be based on demands of the current
market and take into account the relevant informative notes.
This standard still consists of the so-called "empirical" specifications. Work programmes are being undertaken
to evaluate alternative properties 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 XXX 2005,
and the results will be considered for future revisions of this European Standard.
1 Scope
This European Standard provides a framework for specifying the properties and relevant test methods for
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 requirements 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 consistency.
For paving grade bitumen the testing of the above three essential characteristics also gives an indication that
its intrinsic cohesive properties that 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, rather than tests on the bitumen itself.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 12597 apply.
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
The bitumens covered by this European Standard represent one of the constituents in asphalt materials
covered by the European Standards prEN 13108-1 to 13108-7. As the European product standards cover a
large variety of asphalt materials for different applications, traffic loads and climatic conditions, EN 12591 must
also cover a large range of bitumens to facilitate the production and application of these materials. The
variation in the prEN13108 series makes it necessary and practical to split the bitumens - mainly due to the
application – which is the reasons for grouping the grades into three separate tables.
The requirements for the properties for a specific grade must be selected from the three Tables 1, 2 and 3 by
choosing a column representing the specified values or ranges.
Two severity levels for resistance to hardening are stated as alternatives because under specific conditions a
larger increase in softening point ring and ball after RTFOT can be allowed without detrimental effect if this
increase is associated with requirements for either breaking point Fraass or penetration index (Ip).
Due to the Construction Product Directive (CPD) there is a subdivision of characteristics in three groups
horizontally in the tables.
1) First characteristic group is the mandatory requirements (essential requirements) associated with
CPD.
2) Second characteristic group is not mandatory properties but indicates properties which shall be
included in all specifications for other reasons (e.g. health, safety, environment, transport, …).
3) Third characteristic group is optional properties that can be considered as useful information or linked
to climatic or other regional consi
