ASTM C1781/C1781M-15

Standard Test Method for Surface Infiltration Rate of Permeable Unit Pavement Systems

SIGNIFICANCE AND USE
5.1 This test method can be used for acceptance of surface infiltration of new permeable unit pavement systems.  
5.2 Tests performed at the same location across a span of years may be used to detect a reduction of infiltration rate of the permeable surface, thereby identifying the need for any remedial maintenance intended to increase the infiltration rates to predefined levels.  
5.3 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 surface infiltration rate of the entire permeable pavement, multiple locations must be tested and the results averaged.  
5.4 The minimum acceptable infiltration rate is typically established by the design engineer of record or the municipality and can be a function of the design precipitation event.
SCOPE
1.1 This test method covers the determination of the field surface infiltration rate of in place permeable unit pavement systems surfaced with solid interlocking concrete paving units, concrete grid paving units, or clay paving brick.
Note 1: For in-place pervious concrete, Test Method C1701 should be used. Test Method C1701 is functionally identical to this standard, but does not include the added provisions for positioning and securing the test ring to a discontinuous surface, which are detailed in this standard. Both tests methods give comparable results  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 The text of this test method references notes that provide explanatory material. These notes shall not be considered as requirements of the test method.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.1 An infiltration ring is temporarily sealed to the surface of a permeable unit pavement system. These pavements typically
consist of solid concrete paving units conforming to Specification C936C936/C936M, concrete grid paving units conforming to
