What is BS EN 14770 – DSR test for bitumen about?
Bitumen is an essential component of any pavement and is used widely throughout the world. BS EN 14770 is a European standard on bitumen and bituminous binders. The main aim of the BS EN 14770 series is to provide best industry practices to determine the quality and performance of construction materials to meet your specific engineering needs. BS EN 14770 specifies the number of methods using a dynamic shear rheometer (DSR) capable of measuring the rheological properties of bituminous binders. From the test, the norm of the complex shear modulus, IG*I, and its phase angle, δ, at a given temperature and frequency can be calculated, as well as the components G', G'', J', and J'' of the complex shear modulus and of the complex compliance. This method is applicable to un-aged, aged, and recovered bituminous binders, cut-backs, and bituminous binders stabilised from emulsions.
