ABSTRACT Of THE DISCLOSURE Polymer-modified bituminous compositions containing 0.5 to 20% by weight of polymer components, where 20 to 100% by weight of the polymer added is polyalkyl(meth)acrylate, which in synthesized from 50 to 99.8% by weight from C6 to C28 alkyl(meth)acrylates, 0.2 to 20% by weight from polymerizable carboxylic acids and/or sulfonic acids and 0 to 49.8% by weight from one or more other polymerizable, in particular nitrogen-containing compounds. Through the addition of reactive metal compounds, bituminous mixtures with improved elastic recovery, for example ranging from > 50% to about 90%, with low temperature flexibility and high thermal stability are obtained.
