18、e 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 cubic metre (kg/m3); The requirement for the thermometer used in dr

19、y, 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 testing damp specimens, has been corrected; In procedure B, the Note co

20、ncerning 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 has been deleted, with the general rule defined in Clause 5 “Materia

21、ls” 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 specimens has been changed in order to be consistent with new dens

22、ity 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 bituminous specimen. The test methods are intended for use with labo

44、ratory 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 estimated content and accessibility of voids in the specimen: a) bu

45、lk 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 density by dimensions (for specimens with a regular surface and with g

46、eometric shapes, i.e. squares, rectangles, cylinders, etc.). NOTE Annex A (informative) gives general guidance on selecting the appropriate procedure. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applic
