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).”


Safety comes first

Nynas is actively working with customers and contractors to reach the goal of zero injuries at work.

Talking point: The European road network

Three industry experts on the future of Europe's road infrastructure.


Cold mixing on the go

A successful collaboration between Nynas and volumetric concrete mixer manufacturer Armcon has resulted in a mobile patching machine that can produce cold mix asphalt for repairs and maintenance.


Revealing structure

Employing an advanced analysis method, Nynas researchers are starting to unmask the chemical structure of bitumen. Xiaohu Lu explains how TOF-SIMS is used to analyse the surface structure of bitumen.


Investment gaps of more than 20 percent.

The G20’s Global Infrastructure Hub notes in a report that Europe needs to increase road investments by almost USD 1 trillion during 2016–2040.
