16、eword This document (EN 12697-6:2012) has been prepared by Technical Committee CEN/TC 227 “Road materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by

17、 October 2012, and conflicting national standards shall be withdrawn at the latest by October 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such p

18、atent rights. This document supersedes EN 12697-6:2003+A1:2007. The significant changes from that document are: The density of water at test temperature is now obtained from a formula instead of a table; All densities are now expressed in megagram per cubic metre (Mg/m3) instead of in kilogram per c

19、ubic metre (kg/m3); The requirement for the thermometer used in dry, SSD or sealed specimen procedures has been changed; The requirement on the drying of specimens has been changed; The definition of constant mass has been changed; In procedure B, the order of carrying out steps a) to g), when testi

20、ng damp specimens, has been corrected; In procedure B, the Note concerning the saturation period of specimens has been changed and is now limited to a maximum; In procedure A, B and C, the specific requirement for the accuracy of the density of water when calculating the bulk density of specimens ha

21、s been deleted, with the general rule defined in Clause 5 “Materials” being applicable; In procedure C, the formula used to calculate “bulk density dry sealed specimen” has been corrected; In procedure D, the formula used to calculate “bulk density by dimensions” both of cylindrical and rectangular

22、specimens has been changed in order to be consistent with new density units; In the test report, a new paragraph with reference to dimensions of specimens has been added; In Annex A, a paragraph regarding specific requirements for particular method to be used for CE marking has been added.

BS EN 12697-6:2012EN 12697-6:2012 (E) 7 1 Scope This European Standard describes test methods for determining the bulk density of a compacted bi

44、tuminous specimen. The test methods are intended for use with laboratory compacted specimens or specimens from the pavement after placement and compacting, either by coring or sawing. This European Standard describes the following four procedures, the choice of which is used being dependent on the e

45、stimated content and accessibility of voids in the specimen: a) bulk density dry (for specimens with a very closed surface); b) bulk density saturated surface dry (SSD) (for specimens with a closed surface); c) bulk density sealed specimen (for specimens with an open or coarse surface); d) bulk dens

46、ity by dimensions (for specimens with a regular surface and with geometric shapes, i.e. squares, rectangles, cylinders, etc.).
