The intervention divided into 4 lots is included in the three-year framework agreement of ANAS Spa for the execution of scheduled maintenance works on the viaducts of the A2 “Autostrada del Mediteraneo”, including the viaducts “Rago Carr. North”, “Rago Carr. South”, “Stupino Carr. North”, “Stupino Carr South”, “Ruiz Carr. North”, “Ruiz Carr South”.
In particular, Lot 2 concerns scheduled maintenance works at Rago Carr. North and Rago Carr. South viaduct of the A2 motorway “Autostrada del Mediteraneo”. The Rago Viaduct, located in Morano Calabro (CS), is 400 meters long and 147 meters high from the valley floor.
The height of the viaduct deck plate in relation to the ground is particularly high and the viaduct piers are located on the bed of the Rago stream. Therefore, the maintenance works provide for deconstruction of the metal deck with cover plate instead of demolition and subsequent erection of the viaducts by top launching with the help of an avantbec.
