15、. United States15.2 The infiltration rate obtained by this method is valid only for the localized area of the pavement where the test is conducted.To determine the infiltration rate of the entire pervious pavement multiple locations must be tested and the results averaged.5.3 The field infiltration

16、rate is typically established by the design engineer of record and is a function of the design precipitationevent.5.4 This test method does not measure the influence on in-place infiltration rate due to sealing of voids near the bottom of thepervious concrete slab. Visual inspection of concrete core

17、s is the best approach for determining sealing of voids near the bottomof 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 to retainits form when filled with water, and shall have a diamet

18、er of 300 6 10 mm 12.0 6 0.5 in. with a minimum height of 50 mm2.0 in. The bottom 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 o

19、f the ring tothe nearest 1 mm 0.05 in.NOTE 2Ring materials that have been found to be suitable include steel, aluminum, rigid plastic, and PVC.6.2 BalanceA balance or scale accurate to 10 g 0.020.05 kg 0.1 lb.6.3 ContainerAcylindrical container typically made of plastic having a volume of at least 2

20、0 L 5 gal, and from which watermay be easily poured at a controlled rate into the infiltration ring.6.4 Stop WatchAccurate to 0.1 s.6.5 Plumbers Putty (Non-Hardening)Meeting Specification C920 or Federal Specification A-A-3110.6.6 WaterPotable water.7. Test Locations7.1 Perform tests at multiple loc

21、ations at a site as requested by the purchaser of testing services. Unless otherwise specified, usethe following to determine the number of tests to perform:7.1.1 Three test locations for areas up to 2,500 m2 25,000 ft2.7.1.2 Add one test location for each additional 1,000 m2 10,000 ft2 or fraction

22、thereof.7.2 Provide at least 1 m 3 ft clear distance between test locations, unless at least 24 h have elapsed between tests.7.3 Do not test if there is standing water on top of the pervious concrete. Do not test within 24 h of the last precipitation.8. Procedure8.1 Infiltration Ring InstallationCle

23、an the pavement surface by only brooming off trash, debris, and other non-seated material.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 wat

24、ertight seal. Place additional putty as neededNOTE 3In a hot environment where the surface 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

25、rate sufficient to maintain a head between the two marked lines. Use a total of 3.606 0.05 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

26、the nearest 0.1 s.8.3 TestThe test shall be started within 2 min after the completion of the prewetting. If the elapsed time in the prewetting stageis less than 30 s, then use a total of 18.00 6 0.050.25 kg 40.0040.0 6 0.10.5 lb of water. If the elapsed time in the prewettingstage is greater than or

27、 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 tothe nearest 10 g 0.02 lb (M). 0.05 kg 0.1 lb.

Stop timing when free water is no longer present on the pervious surface. Record the testingduration (t)(t) to the nearest 0.1 s.NOTE 4If a sloped pave

29、ment is being measured, maintain head between the two marked lines at the lowest point of the slope.8.4 If a test is repeated at the same location, the repeat test does not require pre-wetting if conducted within 5 min aftercompletion of the first test. If two tests are conducted at a location on a

30、given day, the infiltration rate at that location on that dayshall be calculated as the average of the two tests. No more than two tests shall be conducted at the same location on the sameday.9.

Precision and Bias11.1 Repeatability testing was performed by a single laboratory by making 2 replicate measurements at three locations on anewly placed pervious concrete pavement. The replicate measurements were repeated daily from day 1 to day 10. T

35、hesingle-operator coefficient of variation of the infiltration rate at one test location was found to be 4.7 %.11.2 The multi-operator variability data has not been developed. The reproducibility of this test method is being determined andwill be available on or before October 1, 2014.11.3 This test

36、 method has no bias because the infiltration rate of in-place pervious concrete is defined only in terms of this testmethod.12.
