Paper, 2002Description: 10 sSubject(s): Bibl.nr: VTI 2002.0071Location: Abstract: In order to ascertain the mechanism, by which the de-icing chemicals affect the natural environment, this research examines de-icing chemical scatter patterns and the quantity of road run-off through experiments and a field survey. From the results, it was found that about 10 per cent of the de-icing chemicals end up scattered on the side of the road and around 50 per cent run off into gutters etc. Additionally, it was found found that the quantity of de-icing chemicals scattered on the ground at the side of the road dropped off sharply with distance from the edge of the roadway area. The function can be approximated based on the exponent of the distance from the edge of the roadway area, and overall, it was found that over 50 per cent was scattered within 5 meters of the edge of the roadway area.| Current library | Call number | Status | Date due | Barcode | |
