How does lightweight fill really perform under high-speed rail conditions?

At up to 400 km/h, assumptions are no longer enough. Data matters.

In the next session of BUILD Dialogues, we take a deep dive into the CEDEX Track Box, a unique full-scale (1:1) testing facility in Madrid, where Leca® Lightweight Expanded Clay has been put to the test under real railway conditions.

🎯 What you’ll discover:
✅ Performance and durability of Leca® LWA in railway embankments
✅ Results from static and dynamic testing, simulating train passage at different speeds
✅ Insights from fatigue tests equivalent to 1 million train cycles
✅ A direct comparison with conventional embankment solutions

This session is built around the PEDLER research project, designed to better understand how lightweight solutions behave in high-demand infrastructure applications.

If you’re involved in rail infrastructure, geotechnics or embankment design, this is a conversation you don’t want to miss.
