Designation:D3633/D3633M12Standard Test Method forElectrical Resistivity of Membrane-Pavement Systems1This standard is issued under the fixed designation D3633/D3633M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year 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 This test method covers the measurement of the electri-cal resistivity of water-barrier membrane-pavement systemswhen applied to concrete bridge decks.1.2 Measurements shall be performed on the bituminouspavement surface covering the water-barrier membrane.1.3 This test method utilizes a measure of electrical resis-tance between the saturated top surface of the water-barriermembrane and the reinforcing steel embedded in the concretebridge deck.1.4 The values measured represent the electrical resistanceobtained with the equipment and procedures stated herein anddo not necessarily agree or correlate with those using otherequipment or procedures.1.5 UnitsThe values stated in 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.1.6 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:2C670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsD3743 Terminology Relating to Bridge Deck and Substruc-ture Protection(Withdrawn 2004)3D4071 Practice for Use of Portland Cement Concrete BridgeDeck Water Barrier Membrane SystemsE105 Practice for Probability Sampling of Materials3.Terminology3.1 For definitions of terms used in this specification,referto Terminology D3743.4.Significance and Use4.1 This test method for measuring the electrical resistivityof water-barrier membrane-pavement systems may be inter-preted to indicate the effectiveness of such systems.4.2 This test method is predicated on the fact that anelectrical connection between the surface of the pavement andthe reinforcing steel in the concrete pavement cannot be madethrough an impermeable water-barrier membrane.4.3 This test method may be used for acceptance when theaccepting agency specifies the minimum resistance valuedesired.5.Apparatus5.1 Ohmmeter,dc,20 000/V rating connected to adouble-pole,double-throw switch box or ac ohmmeter(switchbox not required).NOTE1When this test method is used for acceptance,the acceptingagency should specify the type of ohmmeter to be used.5.2 Insulated Wire,No.18,Belden test probewire or equiva-lent.Two spools,minimum 38 m 125 ft.5.3 Copper Plate,305 by 305 by 3.0 mm 12 by 12 by18in.,with the means for connecting the ohmmeter lead and awooden handle approximately 1 m 39 in.in length.5.4 Polyurethane Sponge,305 by 305 by 13 mm 12 by 12by12in.,to be attached to the copper plate with rubber bandsor other suitable means.When assembled this apparatus iscalled the probe.5.5 Pressure Spray Can,12-L 3-gal capacity,with a hoseand spray nozzle.1This test method 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 June 1,2012.Published July 2012.Originallyapproved in 1977.Last previous edition approved in 2006 as D3633 98(2006).DOI:10.1520/D3633-12.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Reagent6.1 A wetting agent which,when added to the water,willbreak the surface tension and promote the penetration of thewater through the bituminous pavement.NOTE2An example of a wetting agent is a super-saturated solution ofcupric sulfate crystals in warm water to which is added 19 mL/gal ofdioctyl sodium sulfo-succinate(Tradename“Aerosol”OT Clear,10%).When ambient test site temperature is below 50F 10C,add 15%byvolume of either isopropyl or denatured alcohol to prevent clouding of thewetting agent.Clouding of the wetting agent may inhibit penetration.7.Sampling7.1 Determine locations on the bridge deck to be tested byusing either a grid pattern similar to that illustrated in Fig.1 orby a random location system,based upon Practice E105 or asimil
