Designation:D608806(Reapproved 2022)Standard Practice forInstallation of Geocomposite Pavement Drains1This standard is issued under the fixed designation D6088;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 practice covers recommendations and identifiespertinent areas of consideration for the installation of buriedgeocomposite drains used for highway edgedrains,under-drains,or other pavement drainage applications meeting therequirements of Specification D7001.These recommendationsare intended as guidelines for developing a satisfactory con-struction and installation method to minimize installation-caused deformation or damage and to provide long-termperformance of these products.It is also intended as a guidelinefor ensuring a stable underground environment for thesematerials under a wide range of service conditions.Because ofthe numerous and diverse product designs available and theinherent variability of natural ground conditions,achievingsatisfactory performance of any one product may requirereview by the engineer and modification to provisions con-tained herein to meet specific project requirements.1.2 The scope of this practice necessarily excludes productperformance criteria such as compressibility in any plane,flowcapacity,inlet capacity,or geotextile selection and use.It is,therefore,incumbent upon the product manufacturer,specifier,and project engineer to verify that the product specified for anintended application,when installed according to proceduresoutlined in this practice,will provide satisfactory long-termperformance according to criteria established by the owner forthat application.A commentary of product performance andinstallation factors important in achieving a satisfactory instal-lation is included in Appendix X1.1.3 The values stated in SI units are to be regarded as thestandard.The inch-pound units given in parentheses are forinformation only.1.4 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D8 Terminology Relating to Materials for Roads and Pave-mentsD420 Guide for Site Characterization for Engineering De-sign and Construction PurposesD653 Terminology Relating to Soil,Rock,and ContainedFluidsD698 Test Methods for Laboratory Compaction Character-istics of Soil Using Standard Effort(12,400 ft-lbf/ft3(600kN-m/m3)D2321 Practice for Underground Installation of Thermoplas-tic Pipe for Sewers and Other Gravity-Flow ApplicationsD2487 Practice for Classification of Soils for EngineeringPurposes(Unified Soil Classification System)D3839 Guide for Underground Installation of“Fiberglass”(Glass-Fiber Reinforced Thermosetting-Resin)PipeD4318 Test Methods for Liquid Limit,Plastic Limit,andPlasticity Index of SoilsD4439 Terminology for GeosyntheticsD7001 Specification for Geocomposites for Pavement EdgeDrains and Other High-Flow ApplicationsF412 Terminology Relating to Plastic Piping Systems3.Terminology3.1 Definitions:3.1.1 Definitions used in this practice are in accordance withTerminologies F412,D8,and D653 unless otherwise indicated.3.2 Definitions:3.2.1 aggregatea granular material of mineral composi-tion such as sand,gravel,shell,slag or crushed stone(seeTerminology D8).1This practice is under the jurisdiction of ASTM Committee D35 on Geosyn-thetics and is the direct responsibility of Subcommittee D35.03 on Permeability andFiltration.Current edition approved May 1,2022.Published May 2022.Originallyapproved in 1997.Last previous edition approved in 2016 as D6088 06(2016).DOI:10.1520/D6088-06R22.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.13.
