ASTM D4402-2015 "Standard Test Method For Viscosity Determination Of Asphalt At Elevated Temperatures Using A Rotational Viscometer"

This standard describes a method for determining the apparent viscosity of asphalt using a rotational viscometer at high temperatures, suitable for the range of 38 to 260 ° C. The testing process involves the use of temperature-controlled hot chambers to ensure temperature stability. This method allows for the assessment of the rheological performance of asphalt at treatment and application temperatures, and is particularly suitable for situations where the performance of asphalt in actual use needs to be predicted. However, as asphalt may exhibit non-newtonian fluid behavior, the results of this method need to be interpreted with caution to avoid misleading practical applications.
