Reparation of a bridge in Alcira with UHPC beams

Background:

In 2019, a concrete bridge in Alcira (Valencia) suffered the impact of a truck, which destroyed its two first “double-T” beams. The contractor requested to RDC the design of the new two beams with UHPC, so if in the future there is a new impact of a truck against them they do not suffer a fragmentation that may hurt the driver. The new “double-T” UHPC beams were prestressed and produced at PREFFOR factory with the dimensions of the undamaged ordinary concrete beams.

Why to use UHPC?

The high fiber content of UHPC implies a high impact strength, so that under an accident the fragmentation of the beam is significantly lower than with ordinary concrete.

Advantages:

  • High impact strength.
  • Improved corrosion strength

Achievements:

  • First reparation of a bridge using UHPC beams in Spain.

The UHPC

UHPC (Ultra-High Performance Concrete) is an extremely compact and ductile cementitious composite. Its properties make it perfect for applications where durability or maintenance play a significant role, where a lightweight structure is particularly relevant, or where the slenderness or thickness of piece is is important.
