Fuel release on pavement during road transportation can cause injuries, deaths, contaminations, great property damages, and a related decreased level of road safety. By referring to hot mix asphalt pavements (HMAs), the choice of appropriate asphalt binders and a specific mix design could give some benefits in disaster mitigation. In the light of above cited problems a device, supported by a suitable experimental procedure, for testing the chemical resistance of different bituminous mixtures to fuels was designed (DIMET road laboratory). A new model for the analysis of the consequences of releases has been proposed; according to a consequent factorial plan of the experiments, porous mixes and dense graded mixes performance in case of fuel spillage have been then compared. The main findings concern the assessment of the best predictors of HMA resistance to fuel actions, in order to estimate how much a transported fluid can be dangerous. © 2007 Taylor & Francis Group, London.
