By rehabilitation is understood the demolition and replacement of the existing bridge deck, repair or replacement of the edge beam in central reservation of the deck side La Louviere which a prestressing cable
was poorly injected, repair batteries, trimmers , beams and struts.
The total tensile force is co posed of three members: the contribution of UHPFRC ([F.sub.t]), classical reinforcement and prestressing cables
. The contribution of UHPFRC is calculated according to the mentioned model of behaviour (10).
For the rehabilitation of bridge, the primary beams have been retrofitted with a new deck of 250 mm thickness ([f.sub.cm] = 35 MPa), which was linked to the existing slab by steel connectors and a system of two external prestressing cables
8/06" strands for each beam.
