Abstract [en]

Increased temperatures and rainfalls will give more settlements and less bearing capacity in gravel roads, which will have implications for the forestry. Pulp mill fly ash without additives was used for stabilizing the road base of a low-volume gravel road. A two-year monitoring of the road was conducted, including measurements of achieved ash content, density, water infiltration capacity, and load bearing capacity. The results showed that the ash-stabilized sections performed better than conventionally upgraded sections and also achieved increased bearing capacity over time. Hydration of the fly ash increased the stiffness and decreased the permeability of the road base. The differences were more pronounced during spring thaw. Best performance was achieved in the section with thicker ash stabilized layer.

Abstract [sv]

Två provsträckor, uppgraderade med olika mängd aska, utvärderades med avseende på ask-grusblandningens homogenitet och skillnader mellan de båda sträckorna. Askgrusblandningens homogenitet varierade i vägen även om den förväntade askhalten uppnåddes i medeltal. Packningsgraden blev lägre än förväntat vilket visar på vikten av omsorgsfull vattning och packning. Provsträckan med störst askhalt hade högst styvhet.
