New pavement in 30 hours for smooth landings

With just one runway, the Sønderborg Airport needed to close down entirely in order to get new pavement. A 70-person Lemminkäinen team ensured that all work was delivered within 30 hours.

Since 2008, Lemminkäinen has been the contractor for maintenance at the small Sønderborg Airport situated in southern Denmark. During their latest annual assessment, it was decided to give the runway a new top layer. But since the local airport has only one runway, the entire airport needed to close down while the work was done.

30 hours non-stop

The 70-person crew worked continuously for 30 consecutive hours to complete the repaving of the runway. At 10:00 am sharp on Saturday, work began by repaving the 1,800 metres long by 30 metres wide runway –70,000 square metres in total – in one coordinated process to obtain the highest possible quality results. We called in extra teams from other regions, since we had to work non-stop to finish on time. And still we made sure we delivered the excellent quality our company is known for.

The work is done in a series of perfectly coordinated movements. The paver is continuously loaded by the feeder, which contains up to 17 tonnes of asphalt at a time. The feeder itself drives slowly up to a long line of trucks, waiting to unload; once a truck is empty it discreetly drives away, back to the plant for a new charge of asphalt.

In Sønderborg, the time challenge was solved perfectly. The schedule was respected and the local community plus the many companies in the region can now benefit from new, safe, high-quality airport pavement that ensures smooth air connections with the rest of Denmark.
