3、ls using water to fill alined test pit to determine the volume of the test pit.The use ofthe word“rock”in these test methods is used to imply that thematerial being tested will typically only contain particles largerthan 3 in.75 mm.1.2 These test methods are best suited for test pits with avolume be
4、tween approximately 3 and 100 ft30.08 and 3 m3.In general,the materials tested would have maximum particlesizes over 5 in.125 mm.These test methods may be used forlarger sized excavations if desirable.1.2.1 This procedure is usually performed using circularmetal templates with inside diameters of 3
5、ft 0.9 m or more.Other shapes or materials may be used providing they meet therequirements of these test methods and the guidelines given inAnnex A1 for the minimum volume of the test pit.1.2.2 Test Method D4914 may be used as an alternativemethod.Its use,however,is usually only practical for volume
6、determination of test pits between approximately 1 and 6 ft30.03 and 0.2 m3.1.2.3 Test Method D1556 or Test Method D2167 is usuallyused to determine the volume of test holes smaller than 1 ft30.03 m3.1.3 The two procedures are described as follows:1.3.1 Procedure AIn-Place Density and Density of Tot
7、alMaterial(Section 12).1.3.2 Procedure BIn-Place Density and Density of Con-trol Fraction(Section 13).1.4 Selection of Procedure:1.4.1 Procedure A is used when the in-place density of thetotal material is to be determined.ProcedureAcan also be usedto determine percent compaction or percent relative
8、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 MethodsD698,D1557,D4253,D4254,and D7382).For Test MethodsD698 and D1557 only,the density determined in the laboratorycompaction t
9、est may be corrected for larger particle sizes inaccordance with,and subject to the limitations of,PracticeD4718.1.4.2 Procedure B is used when percent compaction orpercent relative density is to be determined and the in-placematerial contains particles larger than the maximum particlesize allowed i
10、n the laboratory compaction test methods previ-ously described or when Practice D4718 is not applicable forthe laboratory compaction test method.Then,the material isconsidered to consist of two fractions,or portions.The materialobtained from the in-place density test is physically dividedinto a cont
11、rol fraction and an oversize fraction based on adesignated sieve size.The density of the control fraction iscalculated and compared with the density(ies)established bythe laboratory compaction test method(s).1.4.3 Often,the control fraction is the minus No.4 4.75-mm sieve size material for cohesive
12、or nonfree-drainingmaterials and the minus 3-in.75-mm sieve size material forcohesionless,free-draining materials.While other sizes may beused for the control fraction such as38,34-in.9.5,19-mm,these test methods have been prepared using only the No.44.75-mm and the 3-in.75-mm sieve sizes for clarit
13、y.1.5 Any soil and rock material can be tested,provided thatthe material being tested has sufficient cohesion or particleattraction to maintain stable side walls during excavation of thetest pit and through completion of this test.It should also befirm enough not to deform or slough due to the minor
