Bituminous mixtures - Test methods - Part 32: Specimen preparation by vibratory compactor

This European Standard describes a test method for the preparation of bituminous test specimens using a
vibratory compaction technique.
This European Standard is applicable to loose mixtures and cores and is used to establish a refusal density
for a bituminous mixture, or to determine the ease of compaction as described in EN 12697-10.
If the mixture has been reheated, the specimen shall not be used for determining further mechanical
characteristics.

4 Principle

After the mixing, preparation and conditioning of a bituminous material in the laboratory, the heating of

a core extracted from the road surface to compaction temperature, or the conditioning of plant-mixed

material, the material or core is placed in a standard mould with attached base plate and collar and

compacted by a vibratory hammer.

NOTE For loose material prepared or compacted in the laboratory, or plant-mixed material compacted in the

laboratory, the refusal density is an indication of the potential maximum density which may be achieved under

field conditions.
5 Materials
5.1 Sealing compound.

5.2 Paper discs, to prevent the ends of the specimen from sticking to the base plate or the tamping

foot.
5.3 Silicone grease, for use as a release agent.
5.4 Inert void filling material.
6 Apparatus
6.1 Drying oven, to maintain a temperature of between 25 °C and 45 °C.
6.2 Balance.
6.3 Water bath.
6.4 Split core mould and base plate (see Figure 1).
6.5 One spare base plate.
NOTE Only one spare base plate is needed for a complete set of moulds.
6.6 Heating oven, with fan-assisted circulation.

6.7 Electric vibrating hammer, conforming to Annex A and suitable for laboratory compaction. The

hammer shall have a power consumption of 750 W to 1 000 W and shall operate at a frequency of 20 Hz

to 50 Hz.
6.8 50 mm or 75 mm wide point stripping knife and a pallet knife.

6.9 (102 ± 2) mm diameter tamping foot and a (146 ± 2) mm diameter tamping foot, for use with the

electric vibrating hammer (see 6.7).
6.10 300 mm steel rule.
6.11 Pair of external callipers.
6.12 Stopwatch or clock.
6.13 Thermometer.
