(Test Method)Standard Provisional Test Method for Measurement of Permeability of Bituminous Paving Mixtures Using a Flexible Wall Permeameter (Withdrawn 2003)
Standard Provisional Test Method for Measurement of Permeability of Bituminous Paving Mixtures Using a Flexible Wall Permeameter (Withdrawn 2003)
SCOPE
1.1 This provisional test method covers procedures for determining the relative permeability (also referred to as coefficient of permeability) of water saturated laboratory compacted specimens or field cores of compacted bituminous paving mixtures using a flexible wall permeameter.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 Provisional standards achieve limited consensus through approval of the sponsoring subcommittee.
1.4 This standard is being developed as a provisional standard because the subcommittee feels that the issuance and subsequent usage of this standard method will be critical in the refinement of the standard in the future.
1.5 This provisional 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 requirements prior to use.
