FUEL RESISTANCE OF ASPHALT PAVEMENTS

All materials are exposed to external factors which shorten their functional lifetime. The main factors that affect the lifetime of asphalt pavements are traffic loading, oxidative and UV ageing, ingress of moisture, evaporation of volatile components, exudation, and the exposure to solvents. Although bitumens and asphalt materials are highly resistant to a wide variety of chemicals, due to their hydrocarbon nature they are soluble in fuels and oils. As a result of this, asphalt mixtures tend not to be used in areas where the potential for large scale exposure to fuels and oils exists. Coal tar products have a low solubility in hydrocarbon solvents and consequently have traditionally been used for such applications. However, the use of coal tar products is rapidly diminishing because of health risks associated with the high concentrations of polycylic aromatic compounds (PACs) and lack of availability. Alternative products are therefore needed. Research has shown that the resistance of asphalt mixtures to fuels can be improved by modification of the bitumen binder. The improved fuel resistance in an asphalt mixture is reflected in, among other things, a higher resistance to abrasion after being exposed to fuels. For the covering abstract see ITRD E107185.
