1、Designation: D 5030 04Standard Test Method forDensity of Soil and Rock in Place by the Water ReplacementMethod in a Test Pit1This standard is issued under the fixed designation D 5030; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision

2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the in-place density and unit weight of soil and rock usin

3、g water to filla lined test pit to determine the volume of the test pit. The useof the word “rock” in this test method is used to imply that thematerial being tested will typically contain particles larger than3 in. (75 mm).1.2 This test method is best suited for test pits with a volumebetween appro

4、ximately 3 and 100 ft3(0.08 and 2.83 m3). Ingeneral, the materials tested would have maximum particlesizes over 5 in. (125 mm). This test method may be used forlarger sized excavations if desirable.1.2.1 This procedure is usually performed using circularmetal templates with inside diameters of 3 ft

5、(0.9 m) or more.Other shapes or materials may be used providing they meet therequirements of this test method and the guidelines given inAnnex A1 for the minimum volume of the test pit.1.2.2 Test Method D 4914 may be used as an alternativemethod. Its use, however, is usually only practical for volum

6、edetermination of test pits between approximately 1 and 6 ft3(0.03 and 0.17 m3).1.2.3 Test Method D 1556 or Test Method D 2167 is usuallyused to determine the volume of test holes smaller than 1 ft3(0.03 m3).1.3 The two procedures are described as follows:1.3.1 Procedure AIn-Place Density and Unit W

7、eight ofTotal Material (Section 10).1.3.2 Procedure BIn-Place Density and Unit Weight ofControl Fraction (Section 11).1.4 Selection of Procedure:1.4.1 Procedure A is used when the in-place unit weight oftotal material is to be determined. Procedure A can also be usedto determine percent compaction o

8、r percent relative densitywhen the maximum particle size present in the in-placematerial being tested does not exceed the maximum particlesize allowed in the laboratory compaction test (Test MethodsD 698, D 1557, D 4253, D 4254, D 4564). For Test MethodsD 698 and D 1557 only, the unit weight determi

9、ned in thelaboratory compaction test may be corrected for larger particlesizes in accordance with, and subject to the limitations of,Practice D 4718.1.4.2 Procedure B is used when percent compaction orpercent relative density is to be determined and the in-placematerial contains particles larger tha

10、n the maximum particlesize allowed in the laboratory compaction test or when PracticeD 4718 is not applicable for the laboratory compaction test.Then the material is considered to consist of two fractions, orportions. The material from the in-place unit weight test isphysically divided into a contro

11、l fraction and an oversizefraction based on a designated sieve size. The unit weight ofthe control fraction is calculated and compared with the unitweight(s) established by the laboratory compaction test(s).1.4.2.1 Because of possible lower densities created whenthere is particle interference (see P

12、ractice D 4718), the percentcompaction of the control fraction should not be assumed torepresent the percent compaction of the total material in thefield.1.4.3 Normally, the control fraction is the minus No. 4 sievesize material for cohesive or nonfree-draining materials and theminus 3-in. sieve siz

13、e material for cohesionless, free-drainingmaterials. While other sizes are used for the control fraction (38,34-in.), this test method has been prepared using only the No.4 and the 3-in. sieve sizes for clarity.1.5 Any material can be tested, provided the material beingtested has sufficient cohesion

14、 or particle attraction to maintainstable sides during excavation of the test pit and throughcompletion of this test. It should also be firm enough not todeform or slough due to the minor pressures exerted in diggingthe hole and filling with water.1.5.1 A very careful assessment must be made as to w

The distur-bance during excavation, due to lack of cohesion, and the voidspaces between particles spanned by the liner ma

19、g the test.1.7 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.7.1 In the engineering profession, it is customary practiceto use, interchangeably, units representing both mass and force,unless dynamic calculations (F

20、= Ma) are involved. This im-plicitly combines two separate systems of units, that is, theabsolute system and the gravimetric system. It is scientificallyundesirable to combine the use of two separate systems withina single standard. This test method has been written usinginch-pound units (gravimetri

21、c system) where the pound (lbf)represents a unit of force (weight); however, conversions aregiven in the SI system. The use of balances or scales recordingpounds of mass (lbm), or the recording of density in lbm/ft3should not be regarded as nonconformance with this standard.1.8 This standard does no

22、t purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

30、ize.4. Summary of Test Method4.1 The ground surface at the test location is prepared and atemplate (metal ring) is placed and fixed into position. A lineris laid in the template and the volume of the space between aselected level within the template and the ground surface isdetermined by filling the

31、 space with water. The mass or thevolume of the water required to fill the template to the selectedlevel is determined and the water and liner removed. Materialfrom within the boundaries of the template is excavated,forming a pit. A liner is placed in the test pit and template,water is poured into t

32、he pit and template up to the selectedlevel; the mass or volume of the water within the pit andtemplate and, subsequently, the volume of the hole are deter-mined. The wet density of the in-place material is calculatedfrom the mass of material removed and the measured volumeof the test pit. The moist

33、ure content is determined and the dryunit weight of the in-place material is calculated.4.2 The unit weight of a fraction of the material can bedetermined by subtracting the mass and volume of any oversizeparticles from the initial values and recalculating the unitweight.5. Significance and Use5.1 T

The template must be rigid enough not to deflect orbend.NOTE 1The template shown in Fig. 1 represents a design that hasbeen found suitable for this purpose.6.6.1 Since it may be difficult to place the

41、template exactlylevel, particularly with 6-ft (1.8-m) and larger diameter rings,the height of the template should accommodate a slope ofapproximately 5 %. Since the water level has to be below thetop of the template, it is not necessary that the template belevel. The larger rings should be high enou
