1、Designation:D508008Standard Test Method forRapid Determination of Percent Compaction1This standard is issued under the fixed designation D5080;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in pare

2、ntheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method describes the procedure for rapidlydetermining the percent compaction and the variation fromoptimum moisture content of an in-place soi

3、l for use incontrolling construction of compacted earth.These values areobtained by developing a three-point compaction curve at thesame moisture content as the in-place soil without knowing thevalue of the moisture content.The soil used for the compactioncurve is normally the same soil removed from

4、 the in-placedensity test.For the remainder of this designation,this testmethod will be referred to as the rapid method.1.2 This test method is normally performed for soils con-taining more than 15%fines(minus No.200 sieve size).1.3 When gravel-size particles are present in the soil beingtested,this

5、 test method is limited to a comparison of the minusNo.4 sieve-size fraction of the in-place density material to alaboratory compaction test of minus No.4 sieve-size material(MethodAof Test Methods D698).Subject to the limitations ofPractice D4718,this test method is also applicable to compari-sons

6、of other sieve-size fractions(for example,Method C ofTest Methods D698)or other compactive efforts(for example,Test Methods D1557)if new moisture adjustment values aredetermined(see 6.1 and Appendix X2).1.4 The values stated in SI units are to be regarded as thestandard.1.4.1 The use of balances or

7、scales recording pounds ofmass(lbm),or the recording of density in pounds of mass percubic foot(lbm/ft3)should not be regarded as nonconformancewith this test method.1.5 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026
