ASTM D4 – Standard Test Method for Bitumen Content
Description:
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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
