Standard Test Method for
Bitumen and Aggregate Content of Bitumen-Aggregate
Mixtures From Roofing Samples1

This standard is issued under the fixed designation D 4074; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of the bitumen content of adhered aggregate surfacing on a roof, and the
approximate mass per unit area of the flood coat and adhered
aggregate.

1.2 The values stated in inch-pound units are to be regarded
as the standard.

1.3 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.

2. Referenced Documents

2.1 ASTM Standards:
D 71 Test Method for Relative Density of Solid Pitch and
Asphalt (Displacement Method)2
D 2829 Practice for Sampling and Analysis of Built-Up
Roofs2

3. Summary of Test Method

3.1 The proportions of bitumen and aggregate in a mixture
are determined from their relative densities and the relative
density of their mixture.

4. Significance and Use

4.1 This test method offers a convenient alternative to
solvent extraction for the approximate determination of topcoating bitumen and adhered aggregate in roofing samples,
particularly when the bitumen is coal tar pitch.

5. Apparatus

5.1 Beaker, 500-mL capacity, without a pour spout.3
