ASTM D 2167 : 2015

1.1This test method covers the determination of the in-place density and unit weight of compacted or firmly bonded soil using a rubber balloon apparatus.

1.2This test method is suitable for use as a means of acceptance for compacted fill or embankments constructed of fine-grained soils or granular soils without appreciable amounts of rock or coarse material.

1.3This test method also may be used for the determination of the in-place density and unit weight of undisturbed or in situ soils, provided the soil will not deform under the pressures imposed during the test.

1.4This test method is not suitable for use in organic, saturated, or highly plastic soils that would deform under the pressures applied during this test. This test method may require special care for use on (1) soils consisting of unbonded granular materials that will not maintain stable sides in a small hole, (2) soils containing appreciable amounts of coarse material in excess of 37.5 mm (1¹/₂in.), (3) granular soils having high void ratios, or (4) fill materials containing particles with sharp edges. For soils containing appreciable amounts of particles in excess of 37.5 mm (1¹/₂in.), Test Methods D4914 or D5030 should be used.

1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 unless superseded by this standard.

1.7This 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.
