Zusammenfassung:	Production of polymer-modified bitumen from distillate bitumen (mixture) and a blown bitumen, and 1-15 wt.% used elastomer mixture from a Flexo-printing plate production, comprises preparing the used elastomers for addition to bitumen and purifying so that: (a) the used elastomers in the form of foils or plates containing styrene-isoprene-styrene and/or styrene-butadiene-styrene triblock copolymers, and (meth)acrylate monomers are fixed on a polyester carrier, crushed in a mill (1) under water to a particle sizes of
