Maintenance of infrastructure, including bridges, is a pressing global challenge that drains trillions of investment worldwide. Integral abutment bridges (IABs) are jointless structures without bearings or expansion joints, which require minimum maintenance, hence offering significant cost savings to bridge owners. Thus, providing sustainable and resilient designs, which will enable the use of IABs into longer and more demanding bridges is essential, in view of the expansion of our highways and railways.”

integral bridge and frequent design challenges

The main challenge in IAB design is the interaction of the bridge with the backfill soil. In response to this challenge, we deliver solutions for sustainable IAB designs integrating:

  • use of recycled materials to alleviate the interaction between the bridge and the backfill
  • advanced numerical modelling and understanding of complex bridge backfill interactions under multiple hazards
  • in depth understanding of the risks and the use of mitigation measures to reduce the losses to catastrophes, such as floods and earthquakes
