Designation:D204215Standard Test Method forSolubility of Asphalt Materials in Trichloroethylene1This standard is issued under the fixed designation D2042;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 parentheses 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 the determination of the degreeof solubility in trichloroethylene of asphalt materials havinglittle or no mineral matter.NOTE1This method is not applicable to tars and their distillationresidues or highly cracked petroleum products.For methods covering tars,pitches,and other highly cracked petroleum products,and the use of othersolvents,see Test Methods D4,D2318,and D2764.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 The text 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.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its 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 precautionstatements are given in Section 7.2.Referenced Documents2.1 ASTM Standards:2C670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsD4 Test Method for Bitumen ContentD2318 Test Method for Quinoline-Insoluble(QI)Content ofTar and PitchD2764 Test Method for Dimethylformamide-Insoluble(DMF-I)Content of Tar and PitchD3666 Specification for Minimum Requirements for Agen-cies Testing and Inspecting Road and Paving Materials2.2 AASHTO Standard:3T44 Solubility of Bituminous Materials in Organic Solvents3.Summary of Method3.1 The sample is dissolved in trichloroethylene and filteredthrough a glass fiber pad.The insoluble material is washed,dried,and weighed.4.Significance and Use4.1 This test method is a measure of the solubility of asphaltin trichloroethylene.The portion that is soluble in trichloroeth-ylene represents the active cementing constituents.NOTE2The quality of the results produced by this standard aredependent on the competence of the personnel performing the procedureand the capability,calibration,and maintenance of the equipment used.Agencies that meet the criteria of Specification D3666 are generallyconsidered capable of competent and objective testing/sampling/inspection/etc.Users of this standard are cautioned that compliance withSpecification D3666 alone does not completely assure reliable results.Reliable results depend on many factors;following the suggestions ofSpecification D3666 or some similar acceptable guideline provides ameans of evaluating and controlling some of these factors.5.Apparatus and Materials5.1 The assembly of a typical filtering apparatus is illus-trated in Fig.1.Details of the component parts are as follows:5.1.1 Bitumen Crucible or Gooch Crucible,glazed insideand outside with the exception of outside bottom surface.Theapproximate dimensions shall be a diameter of 44 mm at thetop,tapering to 36 mm at the bottom,and a depth of 20-30 mm.5.1.2 Glass Microfiber Filter Pad,3234 mm diameter,fineporosity,fast flow rate,1.5 m particle retention.5.1.3 Filter Flask,heavy-wall,with side tube,250-,500-,or1000-mL capacity.5.1.4 Filter Tube,40-to 42-mm inside diameter.5.1.5 Rubber Tubing or Adapter,for holding the crucible onthe filter tube.1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.47 onMiscellaneous Asphalt Tests.Current edition approved June 1,2015.Published July 2015.Originally approvedin 1966.Last previous edition approved in 2009 as D2042 09.DOI:10.1520/D2042-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American Association of State Highway and TransportationOfficials(AASHTO),444 N.Capitol St.,NW,Suite 249,Washington,DC 20001,http:/www.transportation.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 NOTE3Other suitable assemblies permitting vacuum filtration with acrucible may be used.5.1.6 Erlenmeyer Flask,125 mL.5.1.7 Oven,capable of maintaining a temperature of 110 65C.6.Reagent6.1 Trichloroethylene,technical grade.7.Safety Precautions7.1 Trichloroethylene is toxic,and good ventilation shouldbe provided.8.Preparation o
