DESCRIPTION

BS EN 14770:2023

This standard BS EN 14770:2023 Bitumen and bituminous binders. Determination of complex shear modulus and phase angle. Dynamic Shear Rheometer (DSR) is classified in these ICS categories:

75.140 Waxes, bituminous materials and other petroleum products
91.100.50 Binders. Sealing materials

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
