New roads in Norway

From this spring until October 2019, NCC will be laying no less than 300 000 tonnes of asphalt on a new section of motorway along the south-eastern coast of Norway.

To achieve a faster, more costefficient work process for the expansion of the strategic road network, the Norwegian road authority created a separate organisation in 2015 known as Nye Veier (New Roads), with an investment budget of NOK 130 billion (EUR 13.5 billion).

The first project that Nye Veier has procured is a 23 kilometre section of motorway with access roads on the E18 between Arendal and Tvedestrand. The new section, which will be opening to traffic in October 2019, is an important element of a long-term project to build a four-lane motorway all the way from Oslo to Stavanger, a section covering around 555 km.

The main contractor for the project – which has a budget of just over NOK 3 billion (EUR 315 million) – is the contracting and industrial company the AF Group. For the surfacing work, the AF Group has in turn engaged NCC Industry.

“It’s our job to lay 300 000 tonnes of asphalt by next autumn,” says NCC’s District Manager Sigve Andersen. “This means that the project is probably the biggest Nordic asphalting assignment ever.”

In other words, there are a number of challenges facing Sigve Andersen and his colleagues, not least in producing such high volumes of asphalt during a relatively short period.

“In view of the tough winter, we’ve started a little bit later than planned. But then at the end of April the weather allows us to work flat out and reach the goal of laying up to 150 000 tonnes between now and end of December, and the remaining volume during 2019.”

15 000 tonnes of bitumen The asphalt will have a thickness of 200 mm, with a surface course of 45 mm. The base course (AG 22) will be needing around 175 000 tonnes of asphalt, while the binder course (AB 11) needs around 70 000 tonnes. The surface course (SKA 16) is produced using Nypol 82, a polymer-modified binder (PMB). The total volume of bitumen is 15 000 tonnes, of which 3 000 tonnes are polymer modified.Another challenge is the logistics. It takes very precise planning to coordinate all the deliveries of aggregate and bitumen so that the right volume of asphalt is delivered to the workplace at the right time. Furthermore, some of the aggregate is arriving by boat, which is more difficult to plan than road transport operations.

“To facilitate the work, we’ve set up a mobile asphalt plant at the construction site,” continues Sigve Andersen. “It has the capacity to manufacture all the asphalt that’s needed, although if problems do arise we also have a stationary asphalt plant in Arendal.”

A third challenge is the environmental aspect. Nya Veier has specified strict requirements not only for environmental consideration, but also for health and safety.

“We’re taking quite a broad range of measures,” explains Sigve Andersen. “Our mobile asphalt plant is powered by gas and we’ll be using 40 000 tonnes of recycled asphalt, mainly in the base course, and also collecting aggregate locally for the binder course and the base course. We’ll also achieve a positive effect in terms of both energy consumption and climate impact by using low-temperature asphalt.”

“Nynas is supplying all the bitumen. One big advantage is that they’ve just started operations at their new PMB plant at the depot in Drammen. This means that we’ll have shorter, safer and eco-friendlier deliveries, as in the past we collected all the PMB from Gothenburg.”

In view of the intensive schedule, NCC will have to lay around 2 000 tonnes of asphalt each day.

“We’ll be using two pavers with full mechanical control to make sure that the asphalt is laid to a high level of precision and also applying a 9.5 metre width for the wearing course,” concludes Sigve Andersen.


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.


All the key players are working together to achieve the best possible result.
