INES Undertakes the Project and Technical Assessment for the Repositioning of Road Viaduct´s Deck in Zaragoza

Posted on

The Z-32 roadway on the right connects northbound the AP-68 toll road with the A-68 highway, in the district of Monzalbarba (Zaragoza). This road has only one structure: a seven-span left-curved viaduct, with a very marked cant (lateral slope), that allows it to overcome both the AP-68 and Zaragoza’s suburban railroad.

Between July and September of 2016, the first part of the deck suffered a transverse displacement with respect to its neoprene bearings (which remained in place) of almost 20 cm in abutment 1, decreasing towards pillar 3. That displacement implied the necessity of an urgent repair, which basically consisted in lifting and stabilizing the deck, prior to moving it transversely and in rotation to its original position.
