The material from the in-place unit weight test is physically divided into a control fraction and an asrm fraction based on a designated sieve size. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

The material being tested should have sufficient cohesion asm particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

It is the responsibility of the user of this standard to establish appropriate f4914 and health practices and determine the applicability of regulatory limitations prior to use. 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. Historical Version s – view previous versions of standard. Then the material is considered to consist of two fractions, or portions.

Combining values from the two systems may result in non-conformance with the standard. While the equipment illustrated in these test methods is used for volumes asrm than 0. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors.

ASTM D4914/D4914M – 16

For r4914 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 determined by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. 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 DDDand D Are you sure you want to unsubscribe monitoring?

Then the material is considered to consist of two fractions, or portions. Please choose number of devices you want to open the document on. This implicitly combines aastm separate systems of units, that is, the absolute system and the gravimetric system.

The accuracy of the test methods may be affected for materials that deform easily or that may undergo volume change in the excavated hole from standing or walking near the hole during the test.

In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. 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 DDDDand D In addition they are representative of the significant digits that generally should be retained.
