Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer
Also Known As:
The ASTM D4402/D4402M-15 standard is titled "Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer". This test method is used to measure the apparent viscosity of asphalts at handling, mixing, or application temperatures.
The standard acknowledges that some asphalts may exhibit non-Newtonian behavior under the test conditions, or at temperatures within the range of the test method. It is important to note that non-Newtonian viscosity values are not absolute properties, but rather reflect the behavior of the fluid within the specific measurement system. Therefore, it may not always predict field performance under actual usage conditions.
Comparisons between non-Newtonian viscosity values should only be made when the measurements are conducted under similar conditions of temperature, shear rate, and shear history.
The test method outlines a procedure for measuring the apparent viscosity of asphalt in the temperature range of 38 to 260°C [100 to 500°F] using a rotational viscometer. A temperature-controlled thermal chamber is used to maintain the test temperature during the measurement process.
