NBN EN 12697-33+A1:2007

This European Standard specifies the methods for compacting parallelepipedal specimens (slabs) of bituminous mixtures, to be used directly for subsequent testing, or from which test specimens are cut.
For a given mass of bituminous mixture, the specimens are prepared either under controlled compaction energy, or until a specified volume and therefore void content is obtained.
This European Standard describes the following methods of compaction:
- pneumatic tyre method,
- steel roller method,
- sliding plates method.
This European Standard is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant.
