SUPERSEDED (see Active link, below)
ASTM D6703
1. Scope
1.1 This test method describes a procedure for quantifying three Heithaus compatibility parameters that estimate the colloidal stability of asphalts and asphalt cross blends (1,2) , aged asphalts (3) , and pyrolyzed heavy oil residua and asphalt (4) using automated Heithaus titrimetry as a stability diagnostic tool.
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 of regulatory limitations prior to use.
