ÖNORM EN 13702-2

This European Standard specifies a method for determining the dynamic viscosity of a modified bituminous binder over a range of temperatures by means of a coaxial viscometer. Although the method has been developed for modified binders, it is also suitable for other binders. NOTE Unlike penetration grade bitumen, polymer modified bitumens (PMBs) do not show a straight line on the Heukelom- Diagram. This implies that in order to obtain information about the temperature susceptibility of PMBs, viscosity should be measured at different temperatures. WARNING ¿ The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
