European foreword
This document (EN 16346:2023) has been prepared by Technical Committee CEN/TC 336 “Bitumens and
bituminous binders”, the secretariat of which is held by AFNOR.
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 June 2024, and conflicting national standards shall be
withdrawn at the latest by June 2024.
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.
This document supersedes CEN/TS 16346:2012.
In comparison with the previous edition, the main technical changes are:
— change of the name of the document, new version does not include the 2/4 aggregate size as the
document now allows the assessment of various aggregate sizes;
— instead of defining the amount of emulsion, which is to be mixed with aggregate, the residual binder
amount was specified (see 8.2.3.);
— assessment of the breaking behaviour (3.3) is now evaluated via washout water appearance in up to
eight beakers (see 8.3.1.) instead of using a slow stream of water;
— immediate adhesivity (3.4) and immediate adhesivity after drying (3.5) are now assessed in a
quantitative way instead of using indicative sketches;
— time when the immediate adhesivity (3.4) is assessed is fixed at 10 minutes (see 8.3.1);
— new procedure for evaluating the adhesivity after a certain rest time was introduced. This procedure
is named “immediate adhesivity after drying” (3.5);
— aggregate (5.2) and washed out aggregate (see 8.3.1 and 8.4.4) are to be dried until a constant
mass (3.6) is reached instead of about a 2 hours drying period;
— new aggregate sizes were introduced (5.1) to have a higher level of versatility;
— the maximum mixing time to obtain the full breaking (3.1) is restricted to 45 seconds (see 8.2.4);
— the possibility to use a camera for depicting the actual state of washout water in beakers was
introduced (see 8.3.1 and 8.4.4);
— pictures depicting different results of the assessment of the breaking behaviour (3.3) were included
in Clause 9.
Any feedback and questions on this document should be directed to the users’ national standards body.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
full breaking
stage at which, during the mixing process between aggregate particles and emulsion conducted as
specified in (8.2), all aggregate particles have agglomerated into a single compact mass
3.2
breaking time
time in seconds, counted from the start of the mixing process, until the full breaking (3.1) is reached
3.3
breaking behaviour
appreciation of the actual degree of breaking of the emulsion after the mixture has reached the full
breaking stage
Note 1 to entry: The breaking behaviour is measured by the number of successive washings of the final mixture
that are necessary until the water runs clear.
3.4
immediate adhesivity
ability of the binder from a bituminous emulsion to resist the action of water just after aggregate coating
Note 1 to entry: Immediate adhesivity is assessed in a quantitative way (loss of mass after washing with water).
3.5
immediate adhesivity after drying
ability of the binder from a bituminous emulsion to resist the action of water after aggregate coating and
after a certain resting time of the coated aggregate was applied before washing
Note 1 to entry: Immediate adhesivity after drying is assessed in a quantitative way (loss of mass after washing
with water).
3.6
constant mass
weight which, on subsequent weighing after drying for at least one hour, does not change by more than
0,1 %
4 Principle
Prescribed quantities of emulsion and aggregate are mixed under specified conditions. The necessary
time to obtain a single agglomerated mass is the measure of the breaking time of the emulsion (3.2). If
full breaking (3.1) is not obtained after 45 s, mixing is stopped. After 10 min, the final mixture is washed
with water and the percentage of residual binder remaining on aggregates is assessed through
weighing (3.4).
If needed or required, the procedure is repeated while spreading coated aggregate evenly and applying
the washing procedure after the curing period of 60 min. This procedure is usually performed when it is
not possible to obtain clear water after 8 successive washings or when the evolution of adhesivity over
time is studied. If not specifically requested, this part is optional.
Depending on the result, additional tests may be conducted at shorter or longer curing periods, e.g.
30 min or 90 min. Such deviations shall be noted in the report.
5 Reagents and materials
5.1 Aggregate, being either reference aggregate or aggregate to be used on a specific job site. Reference
aggregate, which passes through a sieve (see Reference [1]) having a mesh size of 4 mm or 5,6 mm and is
retained on a sieve having a mesh size of 2 mm (sieve sizes shall belong to the [basic set plus set 1]
specified in EN 13043), shall be utilized. Alternatively, aggregate which passes through a sieve having a
mesh size of 6,3 mm or 8 mm and is retained on a sieve having a mesh size of 2 mm, 4 mm or 5 mm (sieve
sizes shall belong to the [basic set plus set 2 and set 1] specified in EN 13043) can be utilized.
NOTE Each country can specify petrographically its own reference aggregates, for instance, in a national
specification document.
