European foreword
This document (prEN 16346:2022) has been prepared by Technical Committee CEN/TC 336 “Bituminous
Binders”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede CEN/TS 16346:2012.
The main changes with respect to the previous document are listed below:
— 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 defined (8.2.3.);
— assessment of the breaking behaviour (3.3) is now evaluated via wash-out water appearance in up
to eight beakers (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 qualitative way by using nomograms;
— time when the immediate adhesivity (3.4) is assessed is fixed at 10 minutes (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 (8.3.1, 8.4.4) is to be dried until a constant mass (3.6) is
reached instead of a drying period of about 2 hours;
— 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 (8.2.4);
— a possibility to use a camera for depicting the actual state of wash-out water in beakers was
introduced (8.3.1, 8.4.4);
— pictures depicting different results of the assessment of the breaking behaviour (3.3) were
included (Clause 9).

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
a 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 minutes, 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 minutes (3.5). 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
