Abstract:The anti fuel oil corrosion performance of five types of stone mastic asphalt(SMA) mixtures was evaluated by laboratory tests. Effects of binder types, anti fuel oil corrosion additive contents, and oil corrosion time on the mechanical and pavement performance were investigated. The oil corrosion mechanism was discovered by the scanning electron microscopy(SEM) and Fourier infrared spectroscopy(FTIR). It is observed that the mixture with the unmodified binder has the maximum reduction in the performance after oil corrosion. The SBS modified binder protects the mixture from oil corrosion in a short time. However, it no longer has any effect after a long time. The mixture with the anti fuel oil corrosion additive can always keep adequate mechanical strength and pavement performance. The optimum content of the additive is 04% of the mixture mass. It has the surface with lamellar quasi flat structures after oil corrosion. Asphalt films are fully retained, indicating the good adhesion capacity and integrity of asphalt mixtures. Adding the additive to the binder can effectively avoid losses of strongly polar aromatic compounds generated from oil corrosion.
