Then the material is considered to consist of two fractions, or portions. 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 determined by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

ASTM D4914

It is undesirable to combine the use of two separate systems within a single standard. While the equipment illustrated in these test methods is used for volumes less than 0. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors.

Do not show this again. Link to Active This link will always route to the current Active version of the standard. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. 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. 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 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 In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in.

However, conversions are given in the SI system. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. For specific hazards statements, see Sections 7 and A1.

Active view current version of standard. The material from the in-place unit weight test is satm divided into a control fraction and an oversize fraction based on a designated sieve size. The printed version is available at half price when you buy the electronic version.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

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. However, for larger sized excavations, Test Method D is preferred.

Atsm 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 addition they are representative of the significant digits that generally should be retained. The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion aastm this test.
