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. 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 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. 1.4 The text of this standard references notes that provide explanatory material. These notes shall not be considered as requirements of the standard.
Permeable pavements are becoming more popular as an environmentally friendly method for providing a functional pavement that also serves as a means to limit and collect stormwater runoff. Unlike conventional pavements that must rely on separate drainage systems to collect and remove stormwater runoff, a permeable system will allow the stormwater to penetrate the surface and drain through a stone base layer for on-site infiltration and filtering. The surface water infiltration rate is a fundamental property of the permeable pavement and is used by the specifier and owner to verify the systems initial performance, to identify the need for remedial maintenance if the surface gets clogged, and to verify the systems performance after any remedial maintenance is performed.
