In bridge abutments embankments or when embankments are constructed connecting to “rigid structures” such as viaducts, bridges or other concrete works, any drop in the level of the approach ramp would be particularly problematic, since it would result in a step that could make the infrastructure unusable.
A lightweight approach ramp embankment made with Laterlite Expanded Clay is ideal for resolving this problem or preventing it from occurring: thanks to the lightweight nature of the aggregate, its optimised granulometric size, and its other properties, which are determined and controlled at the manufacturing stage, it densifies much more easily than traditional aggregates, reduces in volume to a much lesser extent, and avoids settlement by reducing the imposed loading on the supporting ground.
