Designation:D54514Standard Test Methods forPreformed Expansion Joint Fillers for ConcreteConstruction(Nonextruding and Resilient Types)1This standard is issued under the fixed designation D545;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 These test methods cover the physical properties asso-ciated with preformed expansion joint fillers.The test methodsinclude:PropertySectionExpansion in Boiling Water7.1Recovery and Compression7.2Extrusion7.3Boiling in Hydrochloric Acid7.4Asphalt Content7.5Water Absorption7.6Density7.7NOTE1Specific test methods are applicable only to certain types ofjoint fillers,as stated herein.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.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 consult andestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1037 Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel MaterialsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Significance and Use3.1 The compression resistance perpendicular to the faces,the resistance to the extrusion during compression,and theability to recover after release of the load are indicative of ajoint fillers ability to fill continuously a concrete expansionjoint and thereby prevent damage that might otherwise occurduring thermal expansion.The asphalt content is a measure ofthe fiber-type joint fillers durability and life expectancy.In thecase of cork-type fillers,the resistance to water absorption andresistance to boiling hydrochloric acid are relative measures ofdurability and life expectancy.4.Apparatus4.1 Balance,for weighing joint fillers capable of weighingtest specimens within 0.01 g.4.2 Mechanical Convection Oven,capable of maintaining220 6 5.0F(104 6 3C).4.3 Desiccator,of sufficient size to accommodate the testspecimens.4.4 Vernier Caliper,for measuring length and width ofspecimens with accuracy within 60.01 in.(0.25 mm).4.5 Dial Micrometer,or other measuring device,graduatedto read in 0.001-in.(0.02-mm)units.4.6 Extrusion MoldThree-sided steel mold to confinelateral movement of specimens under compression to one sideonly.Interior dimensions shall be 4 by 4 in.(102 by 102 mm)with permissible variations in length and width of 60.015 in.(0.38 mm).Mold sides shall be of such height as to extend atleast 0.5 in.(13 mm)above the test specimens.A typical moldcan be made from a steel base12by 4 by 4 6 0.015 in.(13 by102 by 102 6 0.3 mm)and three bolted steel side plates14in.(6.35 mm)thick,extending approximately 112in.(38 mm)above the base plate,thus forming a three-sided open-top box.4.7 TemplateOne steel template 4 by 4 in.(102 by 102mm),machined from12-in.(6.4-mm)steel plate to fit theextrusion mold.The template shall fit the mold within 0.005in.(0.13 mm)in length and width.1These methods are under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and are the direct responsibility of Subcommittee D04.34 onPreformed Joint Fillers,Sealers and Sealing Systems.Current edition approved June 1,2014.Published August 2014.Originallyapproved in 1939.Last previous edition approved in 2008 as D545 08.DOI:10.1520/D0545-14.2For 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 4.8 Metal Plate,412by 412in.6 0.1 in.(114 by 114 6 2.5mm)with parallel faces machined from12-in.(6.4-mm)steelplate.4.9 Compression Tester,either hydraulic-or screw-typeequipment with sufficient opening between upper-and lower-bearing surfaces to permit the use of verifying apparatus.Theload applied to the test specimen shall be indicated with anaccuracy of 61.0%.The upper-bearing device shall be aspherically seated,hardened metal block firmly attached at thecenter of the upper head of the machine.The center of thesphere shall lie at the center of the surface of the block incontact with the specimen.The block shall be closely held in itsspherical seat,but free to tilt in any direction.Load shall bea
