ASTM D4957-95

Withdrawn Rationale:

This test method describes procedures primarily designed to determine the apparent viscosities of residues obtained by distilling asphalt emulsions according to Test Methods D 244. It is also recommended for use on non-Newtonian asphalts at any temperature within the capability of the apparatus.

Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in March 2005 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 This test method describes procedures primarily designed to determine the apparent viscosities of residues obtained by distilling asphalt emulsions according to Test Methods D244. It is also recommended for use on non-Newtonian asphalts at any temperature within the capability of the apparatus. This test method is useful in characterizing rheological properties of non-Newtonian bitumens as a function of shear rate under the conditions of the test method. This test is run in straight open-end tube viscometers, normally at 140°F (60°C), but is suitable for use at other temperatures. It is applicable over the range from 50 to 500 000 P (5 to 50 000 Pa[dot]s).

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.
