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. Then the material is considered to consist of two fractions, or portions. In general, the materials tested would have a maximum particle size of 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 D, D, D, and D It is zstm possible to buy in the shop – please astn us.

The material from the in-place dry density test is physically divided into a control fraction and an oversize fraction based on a designated sieve size see Section 3. Combining values from the two systems may result in non-conformance with the standard. Do not show this again.

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.

In addition they are representative of the significant digits that generally should be retained. 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.

These test methods have been written ashm inch-pound units gravimetric system where the pound lbf represents a unit of force weight. Historical Version s – view previous versions of standard. The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

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 It is undesirable to combine the use of two separate systems within a single standard.

It is the responsibility of the ashm of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. 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.

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, xstm subject to the limitations of Practice D 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 printed version is available at half price when you buy the electronic version. In addition they are representative of ast significant digits that generally should be retained. However, for larger sized excavations, Test Method D is preferred. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

Then the material is considered to consist of two fractions, or portions. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. While the equipment illustrated in these test methods is used for volumes less than 0.

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.

The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s.
