1、Designation:D5/D5M20Standard Test Method forPenetration of Bituminous Materials1This standard is issued under the fixed designation D5/D5M;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 parenthe
2、ses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers determination of the penetrationof semi-solid an
3、d solid bituminous materials.1.2 The needles,containers,and other conditions describedin this test method provide for the determinations of penetra-tions up to 500.NOTE1See the section on Penetration of Test Methods D244 forinformation and precision and bias on testing emulsion residue.1.3 The value

15、Committee.3.2.1 penetration,nconsistency of a bituminous materialexpressed as the distance in tenths of a millimetre that astandard needle vertically penetrates a sample of the materialunder known conditions of loading,time,and temperature.4.Summary of Test Method4.1 The sample is melted(if starting
16、 at ambient tempera-ture)and cooled under controlled conditions.The penetrationis measured with a penetrometer by means of which a standardneedle is applied to the sample under specific conditions.5.Significance and Use5.1 The penetration test is used as a measure of consistency.Higher values of penetration indicate softer consistency.NOTE2The quality of the results produced by this standard aredependent on the competence of the personnel performing the procedureand the capability,calibration,an
