Bituminous mixtures - Test methods for hot mix asphalt - Part 31: Specimen preparation by gyratory compactor
01-31-2008
07-07-2004
This European Standard specifies the method for compaction of cylindrical 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 can be used fora) determination of the air voids content of a mixture for a given number of gyrations;b) derivation of a curve density versus number of gyrations;c) preparation of specimens of given height at a predetermined density, for subsequent testing of their mechanical properties.For purposes a) and b), the performance based procedure of the annex A specifies a calibration chain so that the result of the test should be independent from the used type of gyratory compactor.For purpose c), compliance with annex A may be not necessary.This European Standard applies to bituminous mixtures (both those made up in laboratory and those resulting from work site sampling), with an upper aggregate size not larger than 31,5 mm.
