Fuel resistance of HMAs: theory and experiments

Fuel spillage on pavement during road transportation can cause deaths, great property damages, and a related decrease level of road safety. Therefore, as far as Hot Mix Asphalts (HMAs) are concerned, the choice of asphalt binders and a specific mix design are of paramount importance in disaster mitigation. In the light of above-mentioned facts, a new model for the analysis of the consequences of fuel spillage has been proposed and validated. The main objectives of the model were the expression of the loss mass (percentage) after soaking in the fuel and after brushing. The purposes of the research were to understand system response to changes in properties, to get a sense for which parameters of bituminous mix control its behavior, and finally to help design the experiments and choose mix type. Laboratory evaluation studies indicate that the formalized models seem to be effective in helping to predict the chemical resistance of HMAs.
