1. Scope

1.1 This test method covers the determination of bulk density ('unit weight') of aggregate in a compacted or loose condition and calculated voids in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 6 in. (150 mm) in nominal maximum size.

Note 1-Unit weight is the traditional terminology used to describe the property determined by this test method, which is weight per unit volume (more correctly, mass per unit volume or density).

1.2 The values stated in either inch-pound units or acceptable metric units are to be regarded separately as standard, as appropriate for a specification with which this test method is used. An exception is with regard to sieve sizes and nominal size of aggregate, in which the metric values are the standard as stated in Specification E11. Within the text, metric units are shown in parentheses. The values stated in each system may not be exact equivalents; therefore each system must be used independently of the other, without combining values in any way.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
