Title:
Abstract:	Die Brücke Grande-Duchesse Charlotte liegt auf dem Kirchberg-Plateau in der Stadt Luxemburg und überspannt das Alzette-Tal im Zuge des so genannten Boulevard John F. Kennedy, welcher die Nationalstraße N 51 führt. Infolge einer geplanten Nutzungsänderung der Brücke wird die Anpassung ihres Verkehrsquerschnitts erforderlich, welcher durch die Überführung einer zweigleisigen Tramtrasse geprägt wird. Im Rahmen dieser projektierten Maßnahme werden umfassende Verstärkungs- und Sanierungsmaßnahmen ausgeführt, um die Dauerhaftigkeit und Tragsicherheit des Bauwerks nach heutigen Standards zu gewährleisten. Die zentrale Maßnahme besteht dabei in der großflächigen Verstärkung der orthotropen Fahrbahnplatte mittels SPS-Overlay. Design and tender of the strengthening of the Grande-Duchesse Charlotte Bridge in Luxembourg - Modification of the traffic composition by appropriate material usage and design. The brigde Grande-Duchesse Charlotte is situated between the city of Luxembourg and the quarter of Kirchberg. The steel bridge carries the Boulevard John F. Kennedy, part of the N 51 over the valley of the Alzette. In view of two tramlines the modification of the traffic composition on the bridge deck is necessary.
