Its use, however, is usually only practical for volumedetermination of test pits between approximately 1 and 6 ft3 (0.030.03 and 0.17 m3).1.2.3 Test Method D1556 or Test Method D2167 is usually used to determi

8、ction of Procedure:1.4.1 Procedure A is used when the in-place unit weight density of total material is to be determined. Procedure A can also beused to determine percent compaction or percent relative density when the maximum particle size present in the in-place materialbeing tested does not excee

11、pplicable for the laboratory compaction test. Then the material is considered to consist of two fractions, or portions. The materialfrom the in-place unit weight density test is physically divided into a control fraction and an oversize fraction based on a designatedsieve size. The unit weight densi

12、ty of the control fraction is calculated and compared with the unit weight(s) density(ies)established by the laboratory compaction test(s).1.4.2.1 Because of possible lower densities created when there is particle interference (see Practice D4718), the percentcompaction of the control fraction shoul

While other sizes are used for the controlfraction (38, 34-in.), this test method has-in. 9.5, 19-mm, these test methods have been prepared using only the No. 4 4.75-mmand the 3-in. 75-mm sieve sizes for clarity.1.5 Any material can be tested, provided the material being tested has sufficient coh

Theaccuracy of the test may be affected for materials that deform easily or that may undergo volume change in the excavated holefrom standing or

The values given in parentheses are for information only.stated in each system may not be exact equivalents; thereforeeach syste

Combining values from the two systems may result in non-conformance withthe standard.1.7.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In this system, the pound (lbf)represents a unit of force (weight), while th

24、e unit for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculationsare involved.1.7.2 In the engineering profession, it is customary practice to use, interchangeably, units representing both mass and force,unless dynamic calculations (F = Ma) are involved. This implicitly comb

25、ines two separate systems of units, that is, the absolutesystem and the gravimetric system. It is scientifically undesirable to combine the use of two separate systems within a singlestandard.

The procedures used do notconsider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives;it is common practice to increase or reduce significant digits of reported data to be commensurate with these consi

Summary of Test Method4.1 The ground surface at the test location is prepared and a template (metal ring) is placed and fixed into position. A liner islaid in the template and the volume of t

41、he space between a selected level within the template and the ground surface is determinedby filling the space with water. The mass or the volume of the water required to fill the template to the selected level is determinedand the water and liner removed. Material from within the boundaries of the

42、template is excavated, forming a pit.Aliner is placedin the test pit and template, water is poured into the pit and template up to the selected level; the mass or volume of the water withinthe pit and template and, subsequently, the volume of the hole are determined. The wet density of the in-place

43、material is calculatedfrom the mass of material removed and the measured volume of the test pit. The moisturewater content is determined and the dryunit weight density of the in-place material is calculated.4.2 The unit weight density of a fraction of the material can be determined by subtracting th

44、e mass and volume of any oversizeparticles from the initial values and recalculating the unit weight.density.5. Significance and Use5.1 ThisThese test method ismethods are used to determine the in-place unit weight density of compacted materials inconstruction of earth embankments, road fills, and s

45、tructure backfill. For construction control, it the test methods can be used asthe basis for acceptance of material compacted to a specified unit weight density or to a percentage of a maximum unit weightdensity determined by a standard laboratory test method such as determined from Test Methods D69

46、8 or D1557, subject to thelimitations discussed in 1.4.5.2 ThisThese test methodmethods can be used to determine in-place unit weight density of natural soil deposits, aggregates,soil mixtures, or other similar material.NOTE 1The quality of the result produced by these test methods are dependent on

47、the competence of the personnel performing them and the suitabilityof the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objectivetesting/sampling/inspection/etc. Users of these test methods are cautioned that compli

48、ance with Practice D3740 does not in itself assure reliable results.Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.6. Interferences6.1 Because of possible lower densities created when there is particle interference (see Practice D4718), t

49、he percent compactionof the control fraction should not be assumed to represent the percent compaction of the total material in the field.6.2 A very careful assessment must be made as to whether or not the volume determined is representative of the in-placecondition when this test method is used for clean, relatively uniform-sized particles 3 in. 75 mm and larger. The disturbanceduring excavation, due to lack of cohesion, and the void spaces between particles spanned by the liner may affect the measurementof the volume of the test pit.7.
