Road at the fair proves its construction design lasts

At Elmia Wood 2017, Nordenväg built a new type of forest road. That short strip is still in place, and the company returned to SkogsElmia 2019 to prove that its road design is longlasting.

“There’s a lot of interest,” says Michael Thorn, who designed the road.

The road is a lightweight causeway for difficult ground conditions. At the fairgrounds, the road was laid on what is almost a wetland with four to five metres down to rock. The alternative is to dig down to firm ground and fill in with another material, which is expensive and time consuming.

In this case, a geogrid was laid directly onto the vegetation and then topped with a 25-centimetre layer of cut-up rubber tyres. Then came a non-woven fabric and then finally 10 centimetres of gravel. Nordenväg supplies the geogrid, rubber and non-woven fabric. Constructing a forest road in this way is much faster than using conventional methods. The road can also be removed after use, while the example at SkogsElmia proves that it is also durable over time.

Starting in spring 2019, all the forest roads in Sweden’s southernmost 10 provinces are being inventoried. That’s a total of 100,000 kilometres of private road, and previous inventories have shown that there are many poor-quality forest roads that must be improved.
