1、Designation: D2397/D2397M 13Standard Specification forCationic Emulsified Asphalt1This standard is issued under the fixed designation D2397/D2397M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A number

2、 in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers seven grades of cationic emul

3、-sified asphalt for use in pavement construction in the mannerdesignated.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other
