1、Designation:D4223/D4223M12Standard Practice forPreparation of Test Specimens of Asphalt-Stabilized Soils1This standard is issued under the fixed designation D4223/D4223M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of las

4、tely as standard.The values stated in each system may not beexact equivalents;therefore,each system shall be used inde-pendently of the other.Combining values from the two systemsmay result in non-conformance with the standard.1.3.1 The gravitational system of inch-pound units is usedwhen dealing wi

5、th inch-pound units.In this system,the pound(lbf)represents a unit of force(weight)while the unit for massis slugs.The rationalized slug unit is not given,unless dynamic(F=ma)calculations are involved.1.3.2 It is common practice in the engineering/constructionprofession to concurrently use pounds to

6、 represent both a unitof mass(lbm)and of force(lbf).This implicitly combines twoseparate systems of units;that is,the absolute system and thegravitational system.It is scientifically undesirable to combinethe use of two separate sets of inch-pound units within a singlestandard.As stated,this standar

7、d includes the gravitationalsystem of inch-pound units and does not use/present the slugunit for mass.However,the use of balances or scales recordingpounds of mass(lbm)or recording in lbm/ft3shall not beregarded as nonconformance with this standard.1.4 This practice offers a set of instructions for
