Straßenfertiger (10) oder auch Beschicker werden von Lastkraftwagen mit Straßenbaumaterial versorgt. Dieses geschieht während des Betriebs des Straßenfertigers (10), der dann den Lastkraftwagen vor sich herschiebt. Dabei liegen Schubrollen (18) des Straßenfertigers (10) an den Hinterreifen des Lastkraftwagens an. Beim sogenannten Andocken des Lastkraftwagens an die Schubrollen (18) des Straßenfertigers (10) kann es zum Abbremsen oder sogar Zurückschieben des Straßenfertigers (10) kommen, was Unebenheiten im frisch hergestellten Straßenbelag zur Folge hat.

Die Erfindung sieht es vor, die Schubrollen (18) mit Strukturdämpfern (27, 28) aus im Wesentlichen Elastomer zu dämpfen und teilweise zu absorbieren. Solche Strukturdämpfer (27, 28) eignen sich besonders zur Herbeiführung eines unter allen Umständen schonenden Andockvorgangs. Das gilt insbesondere, wenn jedes Dämpfungsmittel (22) aus zwei hintereinanderliegenden, unterschiedlichen Strukturdämpfern (27, 28) gebildet ist.
