The influence of runway de-icing agents on the durability of asphalt concrete pavements for airfields
Results and experience from a Norwegian/Swedish joint project on the detrimental effect of runway de-icing agents on asphalt pavements are presented. Exposure of airfield pavements in a weather simulator forms a part of the project.
Laboratory studies of bituminous binders and asphalt concrete have been performed. A certain softening effect was observed in bitumen. The studies found that resistance to de-icing agents increases with increasing hardness of the conventional bitumen. The effect becomes more pronounced with time, temperature and concentration of the chemical. Among the de-icing agents tested, potassium formate and sodium formate had the greatest influence on the binder.
Other significant parameters concerning the de-icing agent are the pH value and the surface tension properties of the solution.
A method has been developed for surface tensile strength. The method has been used for evaluating the pavements in the weather simulator test.
