Bridging past and present in Mauves-sur-Loire
Since 1882, the Mauves-sur-Loire bridge has carried the loads of countless vehicles from point A to point B, and its 570 meters of sturdy trellis beams are a testament to the industrial progress of its time - but every marvel of engineering is due for an upgrade once in a while.
The solution was Ductal®, Holcim’s ultra-high-performance concrete technology (UHPC). Ductal® is responsible for more than 300 bridge repair projects in Europe and North America in just the last five years.
“Through the last 25 years of research and development in our Holcim Innovation Center, Ductal® has developed more durable solutions to retain and reuse existing structures,” says Carlos Piles, Head of Ductal® EMEA & Asia. Rehabilitating the Mauves-sur-Loire bridge is a prime example.
The project aimed to upgrade this historic landmark with an increased bearing capacity and cantilevered footbridges. To meet this challenge, the Mauves-sur-Loire team replaced the existing 3,500-square-meter deck made of brick vaults with precast UHPC slabs averaging just 10cm in depth, reducing the bridge’s total dead load by 50%.
To summarize what Ductal® stands for: it’s our large global footprint, our R&D expertise, and our sustainability commitment.
