DIN EN 12697-6:2012-07 EN 12697-6:2012 (E) 7 1 Scope This European

45、 Standard describes test methods for determining the bulk density of a compacted bituminous 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

46、the following four procedures, the choice of which is used being dependent on the estimated 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 d

47、ensity sealed specimen (for specimens with an open or coarse surface); d) bulk density by dimensions (for specimens with a regular surface and with geometric 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
