Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More D This test method may also be used to determine the in-place density of compacted soils used in construction of structural fill, highway embankments, or earth dams.

When the in-place density is to be used as a basis for acceptance, the drive cylinder volumes must be as large as practical and not less than cm 3 0.

Agencies which meet the criteria of Practice D are generally considered capable of competent and objective testing. Users of this method are cautioned that compliance with Practice D does not in itself assure reliable testing.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. The test method involves obtaining an intact soil sample by driving a thin-walled cylinder into the soil and conducting specific measurements and calculations for the determination of in-place density. When sampling or in-place density is required at depth, Test Method D should be used.

This test method may not be applicable for soft, organic, highly plastic, noncohesive, saturated or other soils which are easily deformed, compress during sampling, or which may not be retained in the drive cylinder sampler. This test may not be applicable with very hard natural soils or heavily compacted soils that may not be easily penetrated with the drive cylinder sampler. The use of this test method in soils containing an appreciable amount of particles larger than 4. Soils containing particles larger than 4.

The procedures, precautions, and requirements necessary for selecting locations for obtaining intact samples, suitable for laboratory testing or otherwise determining engineering properties, is beyond the scope of this test method. The values given in parentheses after SI units are provided for information only and are not considered standard. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system.

It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This test method covers the determination of in-place density of soil by the drive-cylinder method. The test method involves obtaining a relatively undisturbed soil sample by driving a thin-walled cylinder and the subsequent activities for the determination of in-place density. This test method may also be used to determine the in-place density of compacted soils used in construction of structural fill, highway embankments, or earth dams. When the in-place density is to be used as a basis for acceptance, the drive cylinder volumes must be as large as practical and not less than. This test method is not recommended for use in organic or friable soils. This test method may not be applicable for soft, highly plastic, noncohesive, saturated or other soils which are easily deformed, compress during sampling, or which may not be retained in the drive cylinder.
