The features and interdependences between environment and economics, connected to the construction of asphalt road pavements, can be evaluated by a wide diversity of decision support tools. The characteristics of these tools and the complementary informative system provide complex assessments. Their final purpose is to ensure an optimum sustainable constructive solution. The present paper aims, along a comparative analysis, to evaluate the environmental and economic impact resulted from the construction of road pavements with asphalt mixtures that integrate different percentages of RAP. The objective was to highlight the characteristics, benefits and limitations of these procedures and conclude on their usage and viability. The evaluation was performed according to LCA and LCC methodology and facilitated by asPECT computer software. Performing this study was intended to facilitate the researchers and practitioners analytical choice and to offer a personal overview on the topic.
