Abstract [en]

Due to climate change, there is a growing demand for mechanically stabilising forestry roads in Sweden. One way to do this is by addition of cement to the bearing layer of the road. In this study, cement was replaced by a forestry industry fly ash. Mechanical testing showed that a good stabilising effect could be achieved and at a 30% ash addition, it could resist more than 12 freeze-thaw cycles. The environmental impact of the ash addition was assessed using a standard leaching test at a liquid to solid ration of ten. The results indicated that most constituents of the ash remained fairly stable, but that notably chloride, potassium, calcium and sodium was mobilised in the grams per kg of TS range, adding up to about 1 % of the total mass. This may cause an elevated salinity in the emediate vicinity of a road, e g in the ditches, under a short time period, but is not considered to be a major problem for recipients. The results also indicate that the total content is a poor estimate for the leachability of various elements.
