This document specifies 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 document specifies the following four procedures, the choice of which is used being dependent on the estimated content and accessibility of voids in the specimen:

  1. bulk density — dry (for specimens with a very closed surface);

  2. bulk density — saturated surface dry (SSD) (for specimens with a closed surface);

  3. bulk density — sealed specimen (for specimens with an open or coarse surface);

  4. 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.
