Designation:D407015Standard Specification forAdhesive Lubricant for Installation of PreformedElastomeric Bridge Compression Seals in ConcreteStructures1This standard is issued under the fixed designation D4070;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 an adhesive lubricant forfacilitating the insertion and positioning of preformed elasto-meric bridge compression seals in either concrete or steel-facedjoints,and which bonds the seal to the joint faces to waterproofthe joint.1.2 Since a precision estimate for this standard has not beendeveloped,this test method is to be used for research orinformational purposes only.Therefore,this test should not beused for acceptance or rejection of a material for purchasingpurposes.1.3 SI units are the standard.Units in parenthesis are forinformation only.2.Referenced Documents2.1 ASTM Standards:2D1084 Test Methods for Viscosity of Adhesives3.General Requirements3.1 The adhesive lubricant shall be a one-component,moisture-curing,polyurethane compound extended with aro-matic hydrocarbon solvent.The compound shall provide ad-equate lubrication for insertion of the seal into the joint and,inthe actual field application,shall bond the seal to the joint facethroughout repeated cycles of expansion and contraction,effectively sealing the joint against infiltration of moisture.4.Physical Requirements4.1 The material shall conform to the physical propertiesdescribed in Table 1.5.Sampling5.1 Samples of the adhesive lubricant shall be 1 L(1 qt)consisting of a composite taken from three or more separatecontainers chosen at random from the same batch.A batch orlot shall be considered as all finished material that wasmanufactured simultaneously or continuously as a unit prior topackaging.Each of the containers sampled shall be resealedand marked for identification.5.2 Samples shall be taken at the point of manufacture orwarehouse prior to delivery,or at the point of delivery fromeach lot.6.Test Conditions6.1 Tests shall be conducted at standard laboratory condi-tions of 23 6 2C(73.4 6 3.6F).All materials and equipmentshall be held at these conditions prior to test for a sufficienttime to assure equilibrium.7.Specimen Preparation7.1 Using a square-tipped spatula,thoroughly hand-mixapproximately 500 mL(1 pt)of lubricant adhesive in a roundcan for 1 min.8.Apparatus8.1 OvenThe oven shall be a circulating air oven capableof maintaining temperature of 105 6 2C(221 6 4F).8.2 Viscometer,RotationalThe essential instrumentationrequired providing the minimum rotational viscometer analyti-cal capabilities for this method include:8.2.1 A drive motor,to apply a unidirectional displacementto the specimen at a rate from 0.05 to 0.5 rad/s(0.5 to 50 r/min)constant to within 1%.8.2.2 A force sensor with a constant of 0.72 mNm tomeasure the torque developed by the specimen to the rotationaldisplacement of the spindle.8.2.3 A coupling shaft or other means to transmit therotational displacement from the motor to the specimen.8.2.4 A rotational element,spindle or tool of the t-bar typewith bar length between 15 and 48 mm(see Fig.1)to fix thespecimen between the drive shaft and a stationary position.1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.34 onPreformed Joint Fillers,Sealers and Sealing Systems.Current edition approved Jan.1,2015.Published February 2015.Originallyapproved in 1981.Last previous edition approved in 2008 as D4070 08.DOI:10.1520/D4070-15.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 8.2.5 A stand to support,level,and adjust the height of thedrive motor,shaft and spindle.8.2.6 A temperature sensor to provide an indication of thespecimen temperature in the range of 20 to 26C to within60.1C.8.2.7 A data collection device to provide a means ofacquiring,storing,and displaying measured or calculatedsignals,or both.The minimum output signals required forrotational viscosity are torque,rotational speed,temperatureand time.8.2.8 A specimen container to contain the test specimenduring testing.NOTE1Alow-form 600 ml Griffin beaker may be used as a container.8.2.9 Auxilary instrumentation considered necessary or use-ful in conducting this method includes:8.2.9.1 Data analysis capability to provide viscosity,stressor other useful parameters derived from the measured signals.8.2.9.2 A level to indicate the vertical plumb of the dr
