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.
