Impact of Airport De-Icing Chemicals and Freeze-Thaw on Rutting Resistance of Asphalt Mixture in Canada

Acetate-based ice control chemicals have been shown to have less environmental impact compared with traditional de-icing salts. However, their impact on the asphalt pavement’s performance has been underestimated and has drawn the attention of pavement engineers. This study was undertaken to evaluate the effect of de-icing chemicals (potassium acetate) and the freeze-thaw cycle on the rutting resistance of asphalt mixtures. Two types of airport …
