適用范圍：This European standard specifies the method for compaction of cylidrical specimens of bituminous mixtures using a gyratory compactor.Such compaction is achieved by combining a rotary shearing action and a vertical resultant force applied by a mechanical head.The method is used for:a) determination of the air voids content of a mixture for a given number of gyrations or derivation of a curve density(or void content)versus number of gyrations;b) preparation of specimens of given height and/or at a predetermined density,for subsequent testing of their mechanical properties.The equipment used for the method needs to comply with Annex A,Annex B or Annex C.NOTE Annex A is especially suitable for void content evaluation and compaction research and Annex B and Annex C for the preparation of specimens for mechanical testing.This European Standard applies to bituminous mixtures(both those made up in laboratory and those resulting from work site samping),with an upper aggregate size not larger than 31,5mm.
