What keeps our motorways in place?

In Altona, the A7-motorway is built on abutments. A planned expansion of the motorway requires new abutments. It is a complicated task to construct the foundation piles for the abutments and new noise barriers.

NKT Photonics was on the spot when German company, Stump, executed the load tests of the foundation piles on behalf of the road construction company, DEGES.

With our Distributed Strain Monitoring system – based on optical fibers – it became possible to get full load profile along the 30-meter long piles. Traditional sensors only offer discrete measurements.
