Description

This test method covers the determination of bulk density (“unit weight”) of aggregate in acompacted or loose condition, and calculated voids between particles in fine, coarse, or mixedaggregates based on the same determination. This test method is applicable to aggregates notexceeding 125 mm (5 in.) in nominal maximum size.

Note 1–Unit weight is the traditional terminology used to describe the property determinedby this test method, which is weight per unit volume (more correctly, mass per unit volumeor density).

The values stated in either inch-pound units or acceptable metric units are to be regardedseparately 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 metricvalues are the standard as stated in M 92. Within the text, inch-pound units are shown in brackets.The values stated in each system may not be exact equivalents; therefore, each system must beused independently of the other, without combining values in any way.
