3、by the sleeve method.1.2 The sleeve method of determining the density of soil inplace is used for cohesionless,granular soils for which othermethods of determining the density(sand cone,test pit,and thelike)may not be practical.Typically,the sleeve method isapplicable for soils that are predominantl
4、y fine gravel size,with a maximum of 5%fines,and a maximum particle size of34in.(19.0 mm).NOTE1There have been other methods developed for testing cohe-sionless soils.Compared to other methods,this procedure is convenientfor field construction control testing because smaller and lighter equip-ment i
5、s used and the test can be performed in a smaller area.1.3 A calibration equation is necessary in the application ofthis test method to obtain a reliable value of the in-placedensity of the soil(see Annex A1).The calibration equation isused to calculate the density of the soil in place from the mass
6、of dry soil per inch of test hole measured by the sleeve method.1.3.1 The calibration equation is predetermined for a par-ticular soil type that is to be tested.When the soil changessignificantly in either gradation or particle angularity,thecalibration equation may have to be adjusted or redefinedb
7、efore the sleeve method can be used.1.3.2 There may be certain soils meeting the general de-scription in 1.2 for which a calibration equation may not beappropriate due to unsatisfactory correlation of the data.Thesleeve method would not be applicable for these soils.1.3.3 There may be certain soils
8、meeting the description in1.2 for which the calibration equation may be applicable onlyfor a certain range of densities.The sleeve method will givereliable values of the density in place only within that range ofdensities.1.4 This test method uses inch-pound units with SI rational-ized units;that is
9、,a combined standard.1.4.1 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in n
10、on-conformancewith the standard.1.4.2 The converted inch-pound units used the gravitationalsystem of units.In this system,the pound(lbf)represents a unitof force(weight),while the unit for mass is slugs.Theconverted slug unit is not given,unless dynamic(F=ma)calculations are involved.1.4.3 It is com
11、mon practice in the engineering profession toconcurrently use pounds to represent both a unit of mass(lbm)and a unit of force(lbf).This implicitly combines two separatesystems of units;that is,the absolute system and the gravita-tional system.It is scientifically undesirable to combine the useof two
12、 separate sets of inch-pound units within a singlestandard.This standard has been written using the gravitationalsystem of units when dealing with the inch-pound system.Inthis system the pound(lbf)represents a unit of force(weight).However,the use of balances or scales recording pounds ofmass(lbm),o
13、r the recording of density in lbm/ft3should not beregarded as nonconformance with this test method.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026 unless superseded by this standard.1.5.1 The procedures used to sp
14、ecify how data are collected,recorded or calculated in this standard are regarded as theindustry standard.In addition they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpo
