Significance and Use | ||||||
5.1 This test method is used to measure the apparent viscosity of asphalts at handling, mixing, or application temperatures. 5.2 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. 5.3 Comparisons between non-Newtonian viscosity values should be made only for measurements made with similar conditions of temperature, shear rate, and shear history. |

1. Scope | ||||||
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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with 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 of regulatory limitations prior to use.
