• This study the functional performance of super porous asphalt mixtures with two types of aramid fibers against adverse events during their service life. This research was organized in 4 phases: first, particle loss after extreme weather conditions was evaluated. Second, the permeability and clogging resistance was assessed. Third, its resistance to fuel spillage was studied. Fourth, a multi-criteria analysis was performed to determine the best performing mixture considering all the studied variables. Regarding the results, mixture with aramid and polyolefin was the best performing blend according to the multi-criteria analysis. The fiber content allowed for acceptable performance in terms of particle loss despite having a higher void content than the reference mixtures. In addition, a higher permeability and clogging resistance was found, so the use of such fibers did not negatively affect the internal structure of the mixture. Finally, it had a higher resistance to fuel spillage due to the use of polymer-modified bitumen. [Display omitted] •High porous asphalt mixtures were evaluated for adverse conditions during their service life.•High porous mixtures with fibres double the drainage capacity of conventional porous mixtures.•The fuel spill resistance of asphalt mixes depends on the type of binder used, not on the fibres or aggregates.•Extreme weather adversely affects the particle loss resistance of porous mixtures.•The use of PMB binder in high porous mixtures is essential.
