ABSTRACT
In this study, we performed an assessment of the environmental impact caused by the use of Spanish roads from 2004 to 2006. Subsequently, through the application of Life Cycle Assessment (LCA) methodology, this impact was compared with the construction stage of roads, considering the following impact categories: global warming, formation of tropospheric ozone precursors and acidification. The results show the progressive increase of the emissions of the pollutants that cause global warming. Moreover, the importance of the environmental impact associated to the construction stage is reflected. Key words: LCA, global warming, ozone precursors, acidification, road.
