Designation: C1701/C1701M − 17Standard Test Method forInf i ltration Rate of In Place Pervious Concrete 1This standard is issued under the f i xed 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 f i eldwater inf i ltration rate of in place pervious concrete.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.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.

Summary of Test Method4.1 An inf i ltration 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 inf i ltrate the pavement is recorded. The inf i ltrationrate is calculated in accordance with 9.1.5. Signif i cance and Use5.1 Tests performed at the same location across a span ofyears may be used to detect a reduction of inf i ltration rate ofthe pervious concrete, thereby identifying the need for reme-diation.5.2 The inf i ltration rate obtained by this method is validonly for the localized area of the pavement where the test isconducted. To determine the inf i ltration rate of the entirepervious pavement multiple locations must be tested and theresults averaged.5.3 The f i eld inf i ltration 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 inf l uence onin-place inf i ltration 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 Inf i ltration Ring—A cylindrical ring, open at both ends(See Fig. 1). The ring shall be watertight, sufficiently rigid toretain its form when f i lled 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 with twolines at a distance of 10 and 15 mm [0.40 and 0.60 in.] from thebottom of the ring. Measure and record the inner diameter ofthe ring to the nearest 1 mm [0.05 in.].N OTE 1—Ring materials that have been found to be suitable includesteel, aluminum, rigid plastic, and PVC.1 This 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 1, 2017.
