1、Designation:D2172/D2172M17Standard Test Methods forQuantitative Extraction of Asphalt Binder from AsphaltMixtures1This standard is issued under the fixed designation D2172/D2172M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the ye
2、ar of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover the quantitative determinationof asphalt binder content in asphalt mixtures and pavementsamp
3、les.Aggregate obtained by these methods may be used forsieve analysis using Test Method D5444.This test is notappropriate for testing asphalt mixtures containing coal tar.1.2 Asphalt binder may be recovered using Test MethodD1856,Practice D5404/D5404M,or Practice D7906.1.3 Units The values stated in
4、 either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in noncon-formance with the standard.1.4 The tex
5、t of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with it
6、s use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.Specific hazards aregiven in Section 7.NOTE1The results obtained by these test methods may be affected bythe age of
7、 the material tested,with older samples tending to yield slightlylower asphalt binder content.Best quantitative results are obtained whenthe test is made on mixtures and pavements shortly after their preparation.It is difficult to remove all the asphalt when some aggregates are used andsome chloride
