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.
