Norway's new super bridge

The Hålogaland bridge is located 300 km north of the Arctic Circle, and crosses a fjord by the city of Narvik in northern Norway.

 With a free span of 1 145 m the bridge will be one of the longest suspension bridges in Europe when it opens for traffic in the summer of 2018.

With a total length of 1 533 m and an 18 m wide road, this superbridge will need a considerable amount of special asphalt. The paving of the bridge, which starts this spring, will be performed in two separate contracts. One for the two viaducts with a total length of 400 m, which have a concrete surface, and another contract for the road on the suspension span, which is made of steel.

“Here we required two very different recipes and performance methods,” says Erik Sundet from the consultancy company Cowi. “For the concrete surface we need two layers of PMB A34 (80 mm), while the steel surface requires the use of a water-resistant membrane (80 mm).”

In good shape

Most local authorities in the UK think of cold mix asphalt as a new and relatively untested road construction material. But it has been used successfully in the UK for more than 10 years, including a section of trunk road in Scotland built with a cold mix asphalt base course in 2008.

Safety

Knowledge key to safe deliveries

Bitumen is delivered hot and therefore precise procedures are needed in order to minimise safety risks such as burn injuries. Safety is something on which the transport company Kördel maintains a constant focus.
