Bitumen and bituminous binders - Determination of dynamic viscosity by vacuum capillary

This European Standard specifies a method for the determination of the dynamic viscosity of bituminous binders by means of a vacuum capillary viscometer at 60 °C in a range between 0,003 6 Pa⋅s and 580 000 Pa⋅s. Other temperatures are possible if calibration constants are known. Bituminous emulsions are not within the scope of this method. NOTE 1 Emulsions containing bituminous binders are not considered to be covered by this method. This method can be used for recovered and/or stabilized binders obtained from emulsions. NOTE 2 The viscosity behaviour of some polymer modified bitumens (PMB) is not demonstrated in a vacuum capillary viscometer. Other methods are more relevant.
