Standard Test Methods for
Permbability of Bituminous Mixtures’
This standard is issued under the fixed designation D 3637; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (0 indicates an editorial change since the last revision or reapproval.
