provide certain properties
3.2
water susceptibility of filler
measure of the degree of separation which occurs in the presence of water from a filler bitumen mixture,
e.g. as a result of intra-crystalline water inclusion between aggregate particles and binder coating
3.3
subsample
sample obtained from sampling increments or a bulk sample by means of a sample reduction procedure
3.4
test portion
sample used as a whole in a single test
3.5
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
Note 1 to entry: This designation accepts the presence of some particles which will be retained on the upper sieve
(oversize) and some which will pass the lower sieve (undersize).

5.3 Sampling
The laboratory sub-sample shall be taken in accordance with EN 932-1 and reduced in accordance with
EN 932-2, to produce a mass of about 50 g.
5.4 Preparation of test portions
Dry the reduced mass of filler in an oven at a temperature of (110 ± 5) °C to constant mass and cool to
room temperature in a desiccator for at least 90 min. If agglomerates are present in the material, reduce
these agglomerates to powder by means of a spatula. Mix the pulverised agglomerates with the rest of
the sub-sample and sieve the sub-sample through the 0,125 mm sieve. Remix the material passing the
sieve and take (10 ± 0,1) g as the test portion (m0).
5.5 Procedure
Place (50,0 ± 0,5) g of low viscosity bitumen solution (5.1.3) into the conical flask or the tinplate can and
add the test portion of filler to the conical flask or tinplate can. Measure (100 ± 5) ml of demineralized
water into the measuring cylinder.
Place the conical flask or the tinplate with the lead cap and the measuring cylinder in the water bath until
a temperature of (60 ± 1) °C has been reached by the contents of both vessels (checking by means of
thermometers) and maintain this temperature during the test. Stir the contents of the conical flask or the
tinplate can with its lead cap mechanically for (300 ± 5) s and then allow the mixture to stand for
(300 ± 5) s.
Pour the water from the measuring cylinder into the conical flask or the tinplate can with the lead cap
and stir again for (300 ± 5) s.
In the case of use of tinplate can, the supernatant water is to be transferred into a beaker, to see if
uncoated filler has separated.
In the case of a use of a glass conical flask, examine the mixture to see if uncoated filler has separated. If
not, the filler shall be considered as non-susceptible to water.
If the filler separates, or in the case of turbidity of the water, determine the water susceptibility as follows.
Allow the conical flask or the tinplate can and its contents to cool so that the mixture becomes kneadable.
Pour the water and the filler separated from the mixture by kneading in the flask with a spatula and
washing with water. Pour the water and the separated filler into the beaker and repeat the process until
the washing with water becomes clear.
Weigh a dried filter paper and records its mass (m ). Filter the contents of the beaker through the
1
weighed filter paper in a Büchner funnel to the vacuum flask. Remove the last traces of bitumen by

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:
— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at http://www.iso.org/obp
3.1
filler aggregate
aggregate, most of which passes a 0,063 mm sieve, which can be added to construction
materials to provide certain properties
3.2
water susceptibility of filler
measure of the degree of separation which occurs in the presence of water from a filler bitumen
mixture, e.g. as a result of intra-crystalline water inclusion between aggregate particles and
binder coating
3.3
subsample
sample obtained from sampling increments or a bulk sample by means of a sample reduction
procedure
3.4
test portion
sample used as a whole in a single test
3.5
aggregate size
designation of aggregate in terms of lower (d) and upper (D) sieve sizes expressed as d/D
Note 1 to entry: This designation accepts the presence of some particles which will be retained on the
upper sieve (oversize) and some which will pass the lower sieve (undersize).
3.6
particle size fraction
fraction of an aggregate passing the larger of two sieves and retained on the smaller
Note 1 to entry: The smaller sieve size can be zero.
3.7
constant mass
successive weighings after drying at least 1 h apart not differing by more than 0,1 %, by mass
Note 1 to entry: In many cases constant mass can be achieved after a test portion has been dried for a
pre- determined period in a specified oven at (110 ± 5) °C. Test laboratories can determine the time
required to achieve constant mass for specific types and sizes of sample dependent upon the drying
capacity of the oven used.

4 Principle
A mixture of filler and bitumen is stirred in hot water. If filler becomes separated from the
mixture (indicated by the turbidity of the water), the filler is recovered on a filter paper and
weighed.
