Designation:D510112(Reapproved 2017)Standard Test Method forMeasuring the Filtration Compatibility of Soil-GeotextileSystems1This standard is issued under the fixed designation D5101;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 test method covers performance tests applicable fordetermining the compatibility of geotextiles with various typesof water-saturated soils under unidirectional flow conditions.1.2 Two evaluation methods may be used to investigatesoil-geotextile filtration behavior,depending on the soil type:1.2.1 For soils with a plasticity index lower than 5,thesystems compatibility shall be evaluated per this standard.1.2.2 For soils with a plasticity index of 5 or more,it isrecommended to use Test Method D5567(HCR,HydraulicConductivity Ratio)instead of this test method.1.2.3 If the plasticity index of the soil is close to 5,theinvolved parties shall agree on the selection of the appropriatemethod prior to conducting the test.This task may requirecomparison of the permeability of the soil-geotextile system tothe detection limits of the HCR and Gradient Ratio Test(GRT)test apparatus being used.1.3 The values stated in SI units are to be regarded asstandard.The values in parentheses are for information 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD422 Test Method for Particle-Size Analysis of Soils(With-drawn 2016)3D653 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)D737 Test Method for Air Permeability of Textile FabricsD854 Test Methods for Specific Gravity of Soil Solids byWater PycnometerD1587 Practice for Thin-Walled Tube Sampling of Fine-Grained Soils for Geotechnical PurposesD2216 Test Methods for Laboratory Determination of Water(Moisture)Content of Soil and Rock by MassD2487 Practice for Classification of Soils for EngineeringPurposes(Unified Soil Classification System)D2488 Practice for Description and Identification of Soils(Visual-Manual Procedure)D4220 Practices for Preserving and Transporting SoilSamplesD4318 Test Methods for Liquid Limit,Plastic Limit,andPlasticity Index of SoilsD4354 Practice for Sampling of Geosynthetics and RolledErosion Control Products(RECPs)for TestingD4439 Terminology for GeosyntheticsD4491 Test Methods for Water Permeability of Geotextilesby PermittivityD4647 Test Method for Identification and Classification ofDispersive Clay Soils by the Pinhole TestD4751 Test Methods for Determining Apparent OpeningSize of a GeotextileD5084 Test Methods for Measurement of Hydraulic Con-ductivity of Saturated Porous Materials Using a FlexibleWall PermeameterD5101 Test Method for Measuring the Filtration Compat-ibility of Soil-Geotextile SystemsD5567 Test Method for Hydraulic Conductivity Ratio(HCR)Testing of Soil/Geotextile Systems3.Terminology3.1 Definitions:3.1.1 clogging,nin geotextiles,the tendency for a givengeotextile to lose permeability due to soil particles that haveeither become embedded in the fabric openings or have built up1This test method is under the jurisdiction of ASTM Committee D35 onGeosynthetics and is the direct responsibility of Subcommittee D35.03 on Perme-ability and Filtration.Current edition approved Feb.15,2017.Published February 2017.Originallyapproved in 1990.Last previous edition approved in 2012 as D5101 12.DOI:10.1520/D5101-12R17.2For 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 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.1 on the geotextile surface to form a layer with lower permeabil-ity than that of the bulk soil specimen.3.1.2 piping,nthe tendency of the geotextile to let aquantity of soil pass through its plane that may potentially leadto stability concerns in the soil or internal clogging of thegeotextile.3.
