AS/NZS 2341.4:2015 PDF Download

AS/NZS 2341.4:2015 is a standard that outlines the methods for testing bitumen and related roadmaking products to determine their dynamic viscosity using a rotational viscometer. The standard specifies the procedures for measuring the viscosity of various bituminous materials, such as bitumen, cutback bitumen, bituminous emulsions, and polymer modified binders (PMBs).

The testing method described in this standard involves using a rotational viscometer with standard concentric cylinder measuring geometry. The viscosity measurements are conducted at a specific shear rate to ensure consistency and accuracy across different samples. By determining the dynamic viscosity of these materials, it becomes easier to assess their flow characteristics and suitability for roadmaking applications.

AS/NZS 2341.4:2015 is essential in the road construction industry as it provides a standardized approach for measuring the viscosity of bituminous materials. This enables manufacturers, contractors, and regulatory bodies to ensure the quality and performance of these products.
