1、Designation: D2028/D2028M 10Standard Specification forCutback Asphalt (Rapid-Curing Type)1This standard is issued under the fixed designation D2028/D2028M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision.

2、A number 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 Department of Defense.1. Scope1.1 This specification covers cutback petroleum asphalts
