Designation:D629713Standard Specification forAsphaltic Plug Joints for Bridges1This standard is issued under the fixed designation D6297;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.1.Scope1.1 This specification covers the material,testing and appli-cation requirements for a field molded asphaltic plug joint(APJ)used in expansion joint sealing on asphalt concreteoverlay and portland cement concrete decks.The scope of thisspecification is limited to field molded APJ.This moldedelement can consist of multilayer,or single layer,or both,application systems depending upon individual manufacturingrequirements.The details of this specification are limited to thematerials used in the application of APJ.It is recommendedthat a practical means of testing the watertightness aspects ofthe individual systems,either in the field or at the testinglaboratory,be developed.When used on highway bridges,limits on maximum joint movements shall be specificallyidentified for each type of APJ.APJs should not be used formovement applications exceeding 6 25 mm from the installa-tion width.1.2 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are provided forinformation only.1.3 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.2.Referenced Documents2.1 ASTM Standards:2A36/A36M Specification for Carbon Structural SteelD5 Test Method for Penetration of Bituminous MaterialsD36 Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D113 Test Method for Ductility of Bituminous MaterialsD217 Test Methods for Cone Penetration of LubricatingGreaseD5167 Practice for Melting of Hot-Applied Joint and CrackSealant and Filler for EvaluationD5249 Specification for Backer Material for Use with Cold-and Hot-Applied Joint Sealants in Portland-Cement Con-crete and Asphalt JointsD5329 Test Methods for Sealants and Fillers,Hot-Applied,for Joints and Cracks in Asphaltic and Portland CementConcrete Pavements3.Terminology3.1 Acronyms:3.1.1 APJAsphaltic Plug Joint.3.1.2 ABAsphaltic Binder.4.Material4.1 The AB shall be a thermoplastic polymeric-modifiedasphalt conforming to the physical properties in Table 1.4.2 Type of aggregate shall be one of the following:granite,basalt,gabbro,porphyry or gritstones.The specified aggregateshall be crushed,washed,and dried.Specific size and grada-tions of aggregate shall be agreed upon by the purchaser andAPJ manufacturer.The aggregate shall be preweighed andpackaged to avoid confusion on the jobsite.It shall be notedthat specific sizes of aggregate may be proprietary to certainmanufacturers.4.3 The closed cell foam expansion joint filler shall benongassing and capable of withstanding the elevated installa-tion temperature(199C)of the AB and meet SpecificationD5249.4.4 The steel bridging plate shall conform to SpecificationA36/A36M for mild steel.5.Physical Properties5.1 The thermoplastic polymeric modified asphalt samplesshall be melted for sample preparation in accordance toPractice D5167.5.2 The thermoplastic polymeric modified asphalt shallconform to the physical properties prescribed in Table 1.1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.32 onBridges and Structures.Current edition approved July 1,2013 Published August 2013.Originallyapproved in 1998.Last previous edition approved in 2007 as D6297 01(2007).DOI:10.1520/D6297-13.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Dimensions and Tolerances6.1 The size,shape,and dimensional tolerance shall beagreed upon by the purchaser and the producer or supplier.These tolerances shall be in compliance with the field construc-tion specifications.The standard minimum blockout dimen-sions are 50 500 mm;however,it should be noted that valuesfluctuate depending on existing field conditions.7.Procedure7.1 The AB shall be heated to a temperature as specified bythe manufacturer.The melter must be supplied with a continu-ous agitation system and calibrated thermometers.7.2 The specified aggregate shall be heated to the manufac-turers prescribed temperature in a manufacturers recom-mended mixer.The temperature of the specified aggregate shallbe controlled by a di
