Scope*1.1 This test method covers the determination of the field water infiltration rate of in place pervious concre
3、te.NOTE 1For permeable unit pavement systems, Test Method C1781/C1781M should be used. Test Method C1781/C1781M is functionally identicalto this test method but includes added provisions for positioning and securing the test ring to a discontinuous surface. Both tests methods give comparableresults1

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
