- Limited natural resources and landfill space and increasing amounts of ash produced from incineration of bio fuel and solid wastes have created a demand for useful applications of ash of which road construction is one. Here the environmental impact of a fly ash layer in a reconstructed road was evaluated by studying the soil solution chemistry in the ash layer, at two depths in the soil below and at two depths in the ditch using a centrifugation drainage technique. The road was situated about 20 km west of Sollefteå, (63˚ 16� 33�N, 17˚12�52�E) in the middle of Sweden. Two years after the application of the ash the concentrations of zinc were increasing in the ash layer solutions while concentrations of cadmium were stabilising. Below the ash layer in the road an initial increase of the pH was observed and the concentrations of potassium, sulphate and cadmium showed an increase while copper and mercury showed decreasing concentrations in the road and the ditch soil solutions. The concentrations in the ditch soil solutions were generally much lower compared to the road. Concentrations of calcium in the ash layer solutions indicated that hardening had taken place.
