Terminology3.1 Definitions:3.1.1 The terms used in this test method are defined in Terminology C125.4. Summary of Test Method4.1 An infiltration ring is temporarily sealed

8、 to the surface of a pervious pavement. After prewetting the test location, a givenmass of water is introduced into the ring and the time for the water to infiltrate the pavement is recorded. The infiltration rate iscalculated in accordance with 9.1.5. Significance and Use5.1 Tests performed at the

9、same location across a span of years may be used to detect a reduction of infiltration rate of thepervious concrete, thereby identifying the need for remediation.5.2 The infiltration rate obtained by this method is valid only for the localized area of the pavement where the test is conducted.To dete

10、rmine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged.1 This test method is under the jurisdiction of ASTM Committee C09 on Concrete and Concrete Aggregates and is the direct responsibility of Subcommittee C09.49 onPervious Concrete.Cu

Visual inspection of concrete cores is the best approach for determining sealing of voids near the bottomof the

16、pervious concrete slab.6. Apparatus6.1 Infiltration RingA cylindrical ring, open at both ends (See Fig. 1). The ring shall be watertight, sufficiently rigid to retainits form when filled with water, and shall have a diameter of 300 6 10 mm 12.0 6 0.5 in. with a minimum height of 50 mm2.0 in. The bot

17、tom edge of the ring shall be even. The inner surface of the ring shall be marked or scored with two lines at adistance of 10 and 15 mm 0.40 and 0.60 in. from the bottom of the ring. Measure and record the inner diameter of the ring tothe nearest 1 mm 0.05 in.NOTE 1Ring materials that have been foun

Procedure8.1 Infiltration Ring InstallationClean the pavement surface by only brooming off trash, debris, and other non-seated material

22、.Apply plumbers putty around the bottom edge of the ring and place the ring onto the pervious concrete surface being tested. Pressthe putty into the surface and around the bottom edge of the ring to create a watertight seal. Place additional putty as neededNOTE 2In a hot environment where the surfac

23、e temperature is over 38 C 100 F plumbers putty may not adhere to the concrete surface easily.Therefore it is advisable to perform this test during cooler temperature.8.2 PrewettingPour water into the ring at a rate sufficient to maintain a head between the two marked lines. Use a total of 3.606 0.0

24、5 kg 8.0 6 0.1 lb of water. Begin timing as soon as the water impacts the pervious concrete surface. Stop timing when freewater is no longer present on the pervious surface. Record the amount of elapsed time to the nearest 0.1 s.8.3 TestThe test shall be started within 2 min after the completion of

25、the prewetting. If the elapsed time in the prewetting stageis less than 30 s, then use a total of 18.00 6 0.05 kg 40.00 6 0.1 lb of water. If the elapsed time in the prewetting stage is greaterthan or equal to 30 s, then use a total of 3.60 6 0.05 kg 8.0 6 0.1 lb of water. Record the weight of water

26、 to the nearest 10 g0.02 lb (M). Pour the water into the ring at a rate sufficient to maintain a head between the two marked lines and until themeasured amount of water has been used. Begin timing as soon as the water impacts the pervious concrete surface. Stop timingwhen free water is no longer pre

27、sent on the pervious surface. Record the testing duration (t) to the nearest 0.1 s.NOTE 3If a sloped pavement is being measured, maintain head between the two marked lines at the lowest point of the slope.FIG. 1 Dimensions of Infiltration RingC1701/C1701M 1728.4 If a test is repeated at the same loc

If more than one test is two tests are conducted at a location on a given day, the infiltration rate at thatlocation on that day shall be calculated as the average of the two tests. Do no
