FROM ONE ROAD TO ANOTHER

FROM ONE ROAD TO ANOTHER

One of the major advantages of Leca Lightweight Aggregate is that it is possible to reuse the material in different ways. The natural material - clay - is resistant to frost and chemicals and sustainable over time. Leca LWA can actually be excavated from the ground where it was once placed and reused in new geotechnical applications.

Digging up old Leca LWA in the ground and re-using it.

An example of this can be found outside Gothenburg in Sweden. In connection with Skanska's construction of a new residential area in 2008, a new road was also needed. For the new road they dug up old Leca Lightweight Expanded Clay Aggregate from a place outside of the city and used it for the road construction.

Another example of this can be found in a city outside Gothenburg called Kungälv. When rebuilding an interchange in the summer of 2017, about 500m3 of Leca was dug up, which was then recycled when building the new road.

In the picture you can see what the Leca looked like when they dug it up. As you can see, the material had remained intact and there was no problem in reusing it.
