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

Importancia y uso:

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.

5.5 This test method can also be used to demonstrate the infiltration rate of a particular permeable unit pavement system if the drainage joints are filled with the aggregate that is specified for use in that system.
