Important results from the project
Yes, the objectives set at the start were met. The project aimed to improve the load-bearing capacity and durability of Swedish forest roads by testing innovative solutions. The selected technologies (such as geocells, stone mattresses, enzyme stabilisation, different crowns and improved compaction) led to improved performance and durability of forest roads, enhancing transport efficiency and road lifetime. This fulfils the project´s core objective of more sustainable and efficient forest roads.
Expected long term effects
The project is expected to have a long-term impact by improving the performance and sustainability of forest roads. Techniques such as geocells, enzyme stabilisation, stone mattresses and increased compaction will create roads that can withstand heavier loads, have better drainage and require less maintenance. This reduces costs and downtime, boosting the efficiency of the forest industry. The project also contributes to increased accessibility and safety, while reducing environmental impacts.
Approach and implementation
The project involved five forestry companies, each building a pilot road to evaluate a chosen technology. The solutions included geocells, stabilisers, increased compaction, stone mattresses, and crown slope variations. These solutions were tested under actual conditions, with measurements taken before and after traffic and weather exposure. Results were analysed using lightweight deflectometer tests, profile measurements, and visual inspection. The project also included a cost-benefit analysis.
