Designation:C1701/C1701M17aStandard Test Method forInfiltration Rate of In Place Pervious Concrete1This standard is issued under the fixed designation C1701/C1701M;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.Scope*1.1 This test method covers the determination of the fieldwater infiltration rate of in place pervious concrete.NOTE1For permeable unit pavement systems,Test Method C1781/C1781M should be used.Test Method C1781/C1781M is functionallyidentical to this test method but includes added provisions for positioningand securing the test ring to a discontinuous surface.Both tests methodsgive comparable results1.2 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.1.4 The text of this standard references notes that provideexplanatory material.These notes shall not be considered asrequirements of the standard.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:2C125 Terminology Relating to Concrete and Concrete Ag-gregatesC920 Specification for Elastomeric Joint SealantsC1781/C1781M Test Method for Surface Infiltration Rate ofPermeable Unit Pavement Systems2.2 Other StandardsFederal Specification A-A-3110(TT-P-1536A)PlumbingFixture Setting Compound33.Terminology3.1 Definitions:3.1.1 The terms used in this test method are defined inTerminology C125.4.Summary of Test Method4.1 An infiltration ring is temporarily sealed to the surfaceof a pervious pavement.After prewetting the test location,agiven mass of water is introduced into the ring and the time forthe water to infiltrate the pavement is recorded.The infiltrationrate is calculated in accordance with 9.1.5.Significance and Use5.1 Tests performed at the same location across a span ofyears may be used to detect a reduction of infiltration rate ofthe pervious concrete,thereby identifying the need for reme-diation.5.2 The infiltration rate obtained by this method is validonly for the localized area of the pavement where the test isconducted.To determine the infiltration rate of the entirepervious pavement multiple locations must be tested and theresults averaged.5.3 The field infiltration rate is typically established by thedesign engineer of record and is a function of the designprecipitation event.5.4 This test method does not measure the influence onin-place infiltration rate due to sealing of voids near the bottomof the pervious concrete slab.Visual inspection of concretecores is the best approach for determining sealing of voids nearthe bottom of the pervious concrete slab.6.Apparatus6.1 Infiltration RingA cylindrical ring,open at both ends(See Fig.1).The ring shall be watertight,sufficiently rigid to1This test method is under the jurisdiction of ASTM Committee C09 onConcrete and Concrete Aggregates and is the direct responsibility of SubcommitteeC09.49 on Pervious Concrete.Current edition approved March 15,2017.Published May 2017.Originallyapproved in 2009.Last previous edition approved in 2017 as C1701/C1701M 17.DOI:10.1520/C1701_C1701M-17A.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.3http:/*A Summary of Changes section appears at the end of this standardCopyright 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 retain its form when filled with water,and shall have a diameterof 300 6 10 mm 12.0 6 0.5 in.with a minimum height of 50mm 2.0 in.The bottom edge of the ring shall be even.Theinner surface of the ring shall be marked or scored
