AS 2341.4:1994 PDF Download

AS 2341.4:1994 is a standard that specifies the methods for testing bitumen and related roadmaking products to determine their dynamic viscosity using a rotational viscometer. The standard outlines procedures for measuring the viscosity of bituminous materials at a defined shear rate. This is achieved by using a constant rate of rotation viscometer with a standard concentric cylinder measuring geometry.

The standard provides guidelines on the equipment, sample preparation, and testing procedure to accurately determine the dynamic viscosity of bitumen. It ensures that consistent testing methods are followed, enabling reliable and comparable results. By determining the dynamic viscosity, which measures the resistance to flow of the bituminous material under specified conditions, this standard aids in assessing its suitability for roadmaking purposes.
