Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer

Significance and Use

This test method is used to measure the apparent viscosity of asphalts at handling, mixing, or application temperatures.

Some asphalts may exhibit non-Newtonian behavior under the conditions of this test method, or at temperatures within the range of this test method. Since non-Newtonian viscosity values are not absolute properties, but reflect the behavior of the fluid within the particular measurement system, it should be recognized that measurements made by this test method may not always predict field performance under the conditions of use.

Comparisons between non-Newtonian viscosity values should be made only for measurements made with similar conditions of temperature, shear rate, and shear history.


1.1 This test method outlines a procedure for measuring the apparent viscosity of asphalt from 38 to 260°C (100 to 500°F) using a rotational viscometer and a temperature-controlled thermal chamber for maintaining the test temperature.

1.2 The values stated in SI units are to be regarded as the standard. The values given in centimetre gram second (cgs) units and inch-pound units are for information only.

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. See for specific precautionary information.
