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.

Sätaröd-Vä, Sweden

European route 22 (E22) is no less than 5,320 km long, from Holyhead in the UK via the Netherlands, Germany, Sweden and Latvia to Ishim in Russia. The part of the E22 that runs through Sweden plays a major role for the country’s southern region, not least because of the link to the Copenhagen area. The problem is that the road is very busy and accident-prone, and is also close to residential areas that are affected by noise.

Projects

The Rotebro Link, Sweden

County road 267 in northern Stockholm is an important, busy link between the E4 and the E18. To improve the traffic flow on this section, the contractor Svevia has been hired by the Swedish Transport Administration to widen a 6 km section from one to two lanes in each direction.

Projects

Punt Val Mulinaun, Switzerland

High-quality waterproofing of a bridge is generally carried out using mastic asphalt. This is all the more true if there are increased stresses due to climatic conditions or traffic loads. One example is the Punt-Val-Mulinaun arch bridge on the Oberalpstrasse H19 in Graubünden, Switzerland.

Projects

Asphalt in High Cross Slope, Germany

In summer 2017, Nynas delivered a carefully chosen PMB grade, Nypol 25, for asphalt layers of a test track.
