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).”

Projects

Sokndal, Norway

The recently opened Motorcenter Norway offers everything from go-carting to drag racing. Nynas was involved in the project by supplying Nypol HF 105, a polymer-modified bitumen ideal for pavements that are subjected to high stresses.

Gothenburg, Sweden

The Älvsborg Bridge spans the estuary of the Göta Älv river at the entrance to Gothenburg and the biggest port in Scandinavia. The bridge, officially opened in 1966, has a total length of 930 m and a suspended span of 418 m. To guarantee the bridge's functionality and extend its useful life, extensive maintenance work has been under way since 2019, the third and final stage being completed this summer.

Road infrastructure in North-Western Europe

Even though many successful road projects have been completed in Western Europe in recent years, the durability and availability of the road infrastructure needs to be improved.

Paving the way for asphalt 4.0

Digitalisation is making inroads in the asphalt industry. The latest Eurasphalt & Eurobitume (E&E) Congress was held virtually in June. It was a success, but the next E&E event will allow industry stakeholders to meet face-to-face.
