Bitumen and bituminous binders - Specifications for paving grade bitumens
This European Standard provides a framework for specifying a range of properties and relevant test methods for bitumens, which are suitable for use in the construction and maintenance of roads, airfields and other paved areas, together with requirements for evaluation of conformity. This European Standard does not directly address ‘cohesion, adhesion and setting ability’ (see Introduction). NOTE Although industrial bitumens are specified according to EN 13305, it should be underlined that paving grade bitumens, specified according to this European Standard, can also be used for industrial applications.
Bitumen und bitumenhaltige Bindemittel - Anforderungen an Straßenbaubitumen
Diese Europäische Norm stellt ein Rahmenwerk für die Spezifizierung einer Reihe von Eigenschaften und der entsprechenden Prüfverfahren für Bitumen, die geeignet sind für Bau und Erhaltung von Straßen, Flugplätzen (Landeplätzen) und sonstigen befestigten Flächen, sowie Anforderungen für die Bewertung und Überprüfung der Leistungsbeständigkeit zur Verfügung.
Diese Europäische Norm spricht nicht direkt Kohäsion, Adhäsion und Abbindevermögen (siehe Einleitung) an.
ANMERKUNG Obwohl Industriebitumen nach EN 13305 festgelegt sind, wird betont, dass nach dieser Europäischen Norm festgelegte Straßenbaubitumen auch als Industriebitumen verwendet werden können.
Bitumes et liants bitumineux - Spécifications des bitumes routiers
La présente Norme européenne définit un cadre de spécifications associé à une série de propriétés et de méthodes d'essai appropriées aux bitumes utilisables pour la construction et l’entretien des chaussées routières, aéroportuaires et d’autres chaussées, ainsi que les exigences pour l’évaluation et la vérification des performances de consistance.
La présente Norme européenne ne considère pas directement «la cohésion, l’adhésion et l’aptitude au durcissement» (voir Introduction).
NOTE Bien que les bitumes industriels soient spécifiés dans la norme EN 13305, il est rappelé que les bitumes routiers spécifiés dans la présente Norme européenne, peuvent également être utilisés pour des applications industrielles.

Introduction
This draft European Standard describes the performance required for a number of properties of bitumen and
bituminous binders, as shown in Tables 1/2 to Tables 5/6 inclusive. Some of the properties are required by
regulation in at least one EU or EFTA country (see Table ZA.1.1, Table ZA.1.2 and Table ZA.1.3) and some are
included only for the benefit of industry to assist specifying appropriate performances for different end uses.
For paving grade bitumen, the testing of the following also gives an indication that its intrinsic cohesive
properties are adequate for normal use.
a) Consistency at intermediate service temperature;
b) consistency at elevated service temperature;
c) durability of consistency.
The properties of “adhesion” and “setting ability” are indicated by tests used on either the finished asphalt
mixtures or on aggregate-bitumen combinations, i.e. EN 12697–1, EN 12697–11, EN 12697–12 and EN 12697–
26 [[1], [2], [3] and [4]], rather than tests on the bitumen itself.
This draft European Standard still consists of specifications based upon traditional test methods. Work
programs 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 15352 [18], and the results will be considered for future revisions of this draft European
Standard.

1 Scope
This draft European Standard provides a framework for specifying a range of properties and relevant test
methods for bitumens, which are suitable for use in the construction and maintenance of roads, airfields and
other paved areas, together with requirements for evaluation of conformity.
This draft European Standard does not directly address ‘cohesion, adhesion and setting ability’
(see Introduction).
Although industrial bitumens are specified according to EN 13305, it should be underlined that paving grade
bitumens, specified according to this draft European Standard, can also be used for industrial applications.

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
5.1 General
European product standards cover a large variety of road materials for different applications, to accommodate
local traffic loads and climatic conditions. This draft European Standard therefore also covers a large range of
bitumens to facilitate the production and application of the designed paving. The variety of production
techniques and applications makes it more practical to split bitumens into three separate tables.
The requirements for the properties for a specific grade shall be selected from Table 1, Table 2, Table 3,
Table 4, Table 5 and Table 6 by choosing a column representing the specified values or ranges.
There is a subdivision of properties into two groups in the tables. The properties in Table 1, Table 3 and
Table 5 shall be specified for all paving grade bitumens. They are associated with regulatory or HSE
requirements. The properties in Table 2, Table 4 and Table 6 are required to meet specific regional conditions.
They are associated with regulatory or other regional requirements.
Two severity levels for resistance to hardening are stated as alternatives as, under specific conditions, a larger
increase in softening point after Rolling Thin Film Oven Test (RTFOT) may be allowed (i.e. Severity level 2)
without detrimental effect if this increase is associated with requirements for Fraass breaking point or
penetration index (I ) or both.

5.2 Properties and related test methods
5.2.1 General
The properties of paving grade bitumens and related test methods shall be in accordance with Table 1 and
Table 2, or Table 3 and Table 4 or Table 5 and Table 6. When tested by the methods given in the Tables, the
various paving grades shall conform to the limits specified.
The grades are designated by the nominal penetration or viscosity ranges as appropriate.
5.2.2 Consistency at intermediate service temperature
Consistency at intermediate service temperature shall conform to the requirements for penetration value in
Table 1 or Table 3.
5.2.3 Consistency at elevated service temperature
Consistency at elevated service temperature shall conform to the requirements for softening point in Table 1
(penetration graded), softening point or dynamic viscosity in Table 3 (penetration graded), or kinematic
viscosity in Table 5 (kinematic viscosity graded).
5.2.4 Brittleness at low service temperature
Brittleness at low service temperature may be required to meet specific regional conditions in countries
susceptible to extreme cold. Where required, paving grade bitumens shall conform to the requirements for
Fraass breaking point in Table 2 or Table 4.
5.2.5 Temperature dependence of consistency
Temperature dependence of consistency may be required to meet specific regional conditions. Where
required, paving grade bitumens shall conform to the requirement for dynamic viscosity or penetration index
(I ) or both in Table 2.
p
5.2.6 Durability – Resistance to hardening
Durability is demonstrated by compliance with the required surrogate characteristics of “Resistance to
hardening”, defined in Table 1, Table 3 or Table 6.
Resistance to hardening shall be tested according to the Rolling Thin Film Oven Test (RTFOT) in accordance
with EN 12607-1 for binders from Table 1 and Table 3.
Resistance to hardening shall be tested according to the Thin Film Oven Test (TFOT) in accordance with
EN 12607-2 for binders from Table 5.
5.2.7 Other properties
5.2.7.1 Density
Although requirements for the density of paving grade bitumens are not given in this document, density shall
be determined, when necessary, in accordance with EN 15326.
5.2.7.2 Flash point
Flash point shall be determined by the Cleveland open cup method in EN ISO 2592 for binders in Table 1 and
by the Pensky-Martens closed cup method, EN ISO 2719, for binders in Table 3 and Table 5.
For bitumens in Table 1, the Pensky-Martens closed cup method may be used to investigate possible
contamination but is likely to give lower values than the Cleveland open cup method.

5.2.8 Informative properties
Annex C lists the informative properties which suppliers of paving grade bitumen shall make available as
“Reported Values”.
5.3 Release of dangerous regulated substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets. In the
absence of European harmonized test methods, verification and declaration on release/content should be
done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is available at
the Construction website on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/.
5.4 Precision
The test methods referred to in this document include precision statements when 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.
