Then the material is considered to consist of two fractions, or portions. This implicitly combines two separate systems of atsm, that is, the absolute system and the gravimetric system.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. For construction control, these test methods are often used as the bases for acceptance of material compacted to a specified density or to a percentage of a maximum unit weight awtm by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D, D, D, and D The values given in parentheses are for information only.

The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test. It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s.

Agencies that dd4914 the criteria of Practice D are generally considered capable of competent and objective testing. Then the material is considered to consist of two fractions, or portions.

For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D For specific hazards statements, see Asstm 7 and A1.
