In the media: Increased strength for gravel road with ash

Published: 6 May 2021

Can biogas ash be used, without the addition of other binders, to improve the bearing capacity of a forest road? This was a question that was asked in 2009 when a forest road was upgraded with bio-fly ash from a nearby paper mill.

The project, which is part of the Ash program, was a collaborative project between the Swedish Forest Agency, the Swedish Geotechnical Institute and Luleå University of Technology.
