ASTM D4-86(2018)

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: D4 − 86 (Reapproved 2018)
Standard Test Method for
Bitumen Content
This standard is issued under the fixed designation D4; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscript
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.
Although this test method was withdrawn by the Society in June 1966 at the request of Committee D04, the Committee on
Standards has approved its reinstatement under the jurisdiction of Committee D08 on the basis that Procedure No. 2 still applies to
their interest. Procedure No. 1 has been replaced by Method D 2042, Test for Solubility of Asphalt Materials in Trichloroethylene.
