Recipe against moisture, draughts and cold

Although 85 % of all bitumen is used in road applications, there are other applications where bitumen’s properties bring value.

In these industrial applications it is used to insulate against moisture, heat, sound and vibrations among other things. Some of the applications use oxidised bitumen, which has high heat resistance.

These are properties required by Hunton Fiber for their bitumen-impregnated wood fibre panels. The company, based north of Oslo, is one of the Nordic region’s leading producers of wall panels and other wood fibre-based products for the construction industry.

The addition of Nybit I 142 in Hunton’s panels keeps the wall sealed so that moisture and draughts do not penetrate the insulation and cool down the wall. The impregnation process also makes the panels resistant to mould, rot and pests.

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.

Projects

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.

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.
