Robot helps us to rehabilitate an Over Pass in Resita

Abstract

The over pass to be rehabilitated is situated in the northern part of the city Resita and passes the switch yard for railways and the Barzava river.
The substructure of the over pass, consisting of two spans situated on the left bank of the Barzava river, is under passed by a junction arm for the access on the over pass.
In the winter of 2007 an over gauged transport has heavily hit the three monolith reinforced concrete girders of the superstructure.
In spite of the significant damages, the superstructure has kept its bearing capacity needed for a light traffic with a maximum load of 3,5 t.
The paper presents the damages of the superstructure and also the rehabilitation solutions, which involve the adjustment of the geometry of the under passing junction arm as well.
