In the mountainous area of Setesdal in Norway, Veidekke used the short summer season to complete the asphalt core dam at Lisle Urevatn, one month ahead of schedule.

The Urar asphalt core dam is 40 metres tall. The length of the crest is 150 metres. The width of the asphalt core is 50 cm and the two transition zones are 1,5 metres wide each. A total of 1700 m3 asphalt was placed.

As the construction work progressed, the Urar dam was gradually filled with water, until the volume reached approximately 160 million m3. For placing the asphalt- and filter core, custom-made machinery was used, developed by Veidekke.

A few techical data:

Rock volume: 165 000 m3. Core thickness: 0,5 metres. Bitumen content: 6,6 %. Aggregates: Crushed rock. Filter substance: Crushed rock: 0-60 mm.
