Designation:D3745/D3745M95(Reapproved 2015)1Standard Practice forInstallation of Prefabricated Asphalt Reservoir,Pond,Canal,and Ditch Liner(Exposed Type)1This standard is issued under the fixed designation D3745/D3745M;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.1NOTEUnits information was editorially corrected in January 2015.1.Scope1.1 This practice covers the description of suitable materialsand procedures for installing prefabricated asphalt reservoir,pond,canal,and ditch liner(exposed type).1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the 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 establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D5 Test Method for Penetration of Bituminous MaterialsD6 Test Method for Loss on Heating of Oil and AsphalticCompoundsD36 Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD113 Test Method for Ductility of Bituminous MaterialsD312 Specification for Asphalt Used in RoofingD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD2643 Specification for Prefabricated Bituminous Geomem-brane Used as Canal and Ditch Liner(Exposed Type)D2822 Specification for Asphalt Roof Cement,Asbestos-Containing3.Terminology3.1 There are no terms in this practice that require new orother dictionary definitions.4.Significance and Use4.1 The practices described are only for water bearingreservoirs,ponds,canals,and ditches.5.Materials5.1 The materials needed for the installation consist of thelining sheets,a joint sealant(either a hot-mopped asphalt or acold-applied asphalt mastic type),and batten or cover strips forthe joints between sheets;all of which are manufactured forcompatibility to prevent exudation.5.2 The lining sheets should conform to SpecificationD2643.5.3 The hot-mopped asphalt joint sealant should conform toone of the following specifications:5.3.1 Specification D312,Types II,III,or IV.5.3.1.1 The choice of which type of roofing asphalt to usefor a particular application will be influenced by climaticconditions and must be determined by the installer.5.3.2 An asphalt manufactured to the requirements in Table1.5.3.3 Test MethodsThe properties specified in Table 1may be determined as follows:5.3.3.1 Flash PointTest Method D92.5.3.3.2 Softening PointTest Method D36.5.3.3.3 PenetrationTest Method D5.5.3.3.4 DuctilityTest Method D113.5.3.3.5 Weight LossTest Method D6.5.3.3.6 Asphalt Soluble in Trichloroethylene Test MethodD2042.5.4 The cold-applied joint sealant should meet the require-ments of Specification D2822 and should have the approval ofthe manufacturer of the lining material.1This practice is under the jurisdiction of ASTM Committee D35 on Geosyn-thetics and is the direct responsibility of Subcommittee D35.10 on Geomembranes.Current edition approved Jan.1,2015.Published February 2015.Originallyapproved in 1978.Last previous edition approved in 2006 as D3745 95(2006).DOI:10.1520/D3745_D3745M-95R15E01.2For 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 5.5 The batten or cover strips should meet the requirementsof Specification D2643,except with a minimum thickness of 8mm 516in.and a width of 203 mm 8 in.,unless othermaterials or thicknesses are recommended by the lining manu-facturer or agreed upon between the purchaser and seller.6.Preparation of Subgrade6.1 Prepare the subgrade,whether soil,brick,concrete,orother substrate,by whatever means are necessary to removeany irregularities that might puncture or deform the lining.6.2 The subgrade should be designed to support the load ofthe particular installation under consideration.Compaction ofthe soil to give a minimum 95%modified proctor density isrecommended.7.Cleaning the Liner Sheets7.1 Remove parting material from the lining prior to instal-lation.The cleaning equipment required will be determined bythe type of parting material used to separate the sheets duringshipment.Removal of some parting material may simply mean
