Standard Test Method for Bitumen Content

ABSTRACT
This test method covers the determination of bitumen content in materials containing at least 25 % bitumen. The sample shall be representative, and if it contains more than 2 % of water it shall be dehydrated. The procedures for the determination of bitumen content in materials are presented in details.
SCOPE
1.1 This test method covers the determination of bitumen content in materials containing at least 25 % bitumen. Bitumen content may usually be expeditiously and accurately determined by Procedure No. 1, Section 7. However, some bituminous materials containing finely divided mineral matter may clog the filter or the mineral residue may not be easily retained, in which cases Procedure No. 2, Section 8, shall be followed.
1.2 This 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 and regulatory limitations prior to use. For specific precautionary information, see Section 4.

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 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 Although this test method was withdrawn by the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 Procedure No. 1 has been replaced by Method D 2042,
