DIN EN 13702:2010-11

The document EN 13702:2010 has been prepared by Technical Committee CEN/TC 336 "Bituminous binders", the secretariat of which is held by AFNOR (France). The responsible German Committee is Joint Committee NA 062-03-32 GA "Bitumen; Prüfverfahren und Anforderungen für die Bindemittel" ("Bitumen; test methods and specifications of binders") of the Materials Testing Standards Committee (NMP) and of the Building and Civil Engineering Standards Committee (NABau). The following changes have been made with respect to DIN EN 13702-1:2004-03: a) number has been changed to EN 13702; b) notes 1 and 2 in clause 6 have been added to the normative text; c) standard has been editorially revised. 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 cone and plate viscometer. Although the method has been developed for modified binders, it is also suitable for other bituminous binders. The sample is placed on a plate, a cone is pressed onto the sample and the system is brought to the test temperature. A stress is applied to the sample by rotation. The torque is measured from the applied shear rate and the dynamic viscosity is calculated.
