European foreword
This document (EN 13108-31:2019) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2019, and conflicting national standards shall
be withdrawn at the latest by March 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
A list of all parts of the EN 13108 series can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
The aim of this document is to enable specification of asphalt concrete mixtures with bituminous
emulsion on a performance basis. In general, however, there are currently more empirical tests
available to describe the mixtures.
This document covers a large variety of materials for different applications, traffic and climate
conditions. The standard gives properties and listings of possible categories. It has to accommodate the
road industry for all of Europe. For this reason, the menu approach for properties has been chosen. The
tables represent categories that are required all over Europe. For this reason, numerical values in tables
do not always obey statistical rules. Based on conditions of use, specific properties and categories may
be defined, in documents related to the application of the product. The categories defined in those
documents take into account the reproducibility of the test when this is given in the appropriate test
method.
Care is to be taken to only select those tests which are applicable to the application of the asphalt and
the use of the pavement and to avoid a combination of potentially conflicting requirements.
1 Scope
This document specifies requirements for plant mixtures of the mix group Asphalt concrete with
bituminous emulsion for use on roads, and other trafficked areas. Asphalt concrete with bituminous
emulsion is used for surface courses, binder courses, regulating courses, and bases. It is a mixture in
which mechanical properties evolve over time following installation. This is not just in terms of cooling,
as other asphalts but also includes curing effects.
NOTE Asphalt concrete with bituminous emulsion is a mixture in which mechanical properties evolve over
time following installation because of curing.
Mixtures utilizing bituminous emulsion based on in situ recycling are not covered by this document.
This document includes requirements for the selection of the constituent materials. It is designed to be
read in conjunction with:
— Annex A Product Type Assessment (Normative);
— Annex B Factory Production Control (Normative);
— Annex C Performance characteristic assessment (Informative).

The minimum binder content may be defined in documents related to the application of the product and
shall be selected to the nearest 0,1 %, between values of 3,0 % till 8,0 % for a mixture in which the
aggregate density is assumed to be equal to 2,65 Mg/m .
The selected minimum binder content shall be expressed as B where x is the minimum soluble
minx
binder content in percentage.
The minimum binder content of the mixture shall be corrected by multiplying by the factor
2,650
α =
ρ
where
ρ is the weighted mean of the particle density of the aggregates at the target grading, in megagram
per cubic metre (Mg/m ), determined according to the appropriate clause or annex of EN 1097-6.
The appropriate particle density according to EN 1097-6 shall be declared in the product type
assessment report as defined in Annex A.
NOTE 1 For normal weight aggregates with water absorption less than about 1,5 %, the pre-dried particle
density method as defined in EN 1097-6:2013, Annex A is applicable for aggregates passing the 63 mm test sieve
and retained on the 0,063 mm test sieve. EN 1097-6:2013, Annex G is applicable to aggregates passing the
31,5 mm test sieve including the 0/0,063 mm size fraction.
Based on experience in the place of use for certain specific aggregates with particular granulometric
characteristics, the corrected minimum binder content may be adjusted appropriately. The adjustment
shall be defined in documents related to the application of the product.
For mixtures including reclaimed asphalt, the soluble binder content is the addition of the soluble
added binder content and the soluble binder content of the reclaimed asphalt.
The minimum added binder content may be defined in documents related to the application of the
product and shall be selected to the nearest 0,1 %.
Depending on the characteristics of the recovered binder, the type and the amount of reclaimed asphalt,
the type of emulsion, the contribution of the recovered binder may be defined in documents related to
the application of the product.
NOTE 2 The binder of the reclaimed asphalt can be considered as active, partially active or inactive in the
contribution to the properties of the mixture.

5.3.2.1 Void content
The range of categories of minimum and maximum void contents is defined in Table 4.
The void content shall be determined in accordance with EN 12697-8 using the conditions defined in
Annex A.
The compaction of test specimens shall be selected from Annex A.
In documents related to the application of the product, categories or classes for the voids content may
be defined when appropriate as maximum and minimum categories selected from Table 4.
