6.2.2 Extraction method
6.2.2.1 Test conditions
Temperature : (23 ± 2) °C,
relative humidity : (50 ± 20) % RH,
test piece conditioning : minimum 2 h.
6.2.2.2 Equipment
— Soxhlet extractor or similar,
— balance accurate to ± 0,01 g,
— drying oven at controlled temperature (105 ± 2) °C,
— trichloroethylene, perchloroethylene, methylene chloride, toluene or xylene solvents.
6.2.2.3 Procedure
The test piece is placed in a container (the test piece may be cut into strips provided that any fragment
of material which become detached are recovered and placed in the container) which has been
previously dried and weighed (M ) and provided with a cotton plug or other appropriate closure.
1
Reweigh the container with the test piece and the closure (M ) and place in the extractor. Arrange so
2
that the opening fitted with the closure projects beyond the level of the solvent.
Continue the extraction until the solvent is colourless in the extractor.
Remove the container for drying, initially in air (30 min), then in a drying oven controlled at a
temperature of (105 ± 2) °C until a constant mass for the sample is achieved (constant mass means that
the difference between two consecutive weightings is less than or equal to 0,05 g).
Weigh the container fitted with the closure (M ).
3
Repeat this procedure for the two remaining test pieces.
6.2.2.4 Expression of results
In the extraction test, the following masses are determined for each test piece:
— test piece M – M ,
2 1
— mass of bitumen M – M .
2 3
For each test piece, express the final result in grams per square metre. Calculate the arithmetic mean
value of the test specimens (three for monolayer and two for multilayer).

weigh them together (P1).
Put the sample with the container in a calcinating oven at 600°C for 2 h.
After, weigh the sample with the container (P2).
Repeat this procedure for the two remaining test pieces.
