Life Cycle Assessment Applied to Road Pavements: An Analysis of Method and Results Relevancy

Résumé

The use of Life Cycle Assessment (LCA) for evaluating environmental performances of products is becoming usual in Europe. In that context, many studies have been published aiming at comparing different technologies for construction and maintenance of pavements. The paper examines and compares studies performing LCA of pavements, with the aim of pulling out important parameters that can explain different results. The first step of this paper consists of selecting some of the available studies on different criteria. In a second part, the paper examines the main hypothesis of selected studies highlighting differences and similarities. In the last part, the paper compares results in link with chosen hypothesis. Apart from possible differences between environmental data sources, several tendencies can be highlighted on selected studies. The use of steel inside continually reinforced concrete pavements (CRCP) materials conducts to an important increase in both energy consumption and greenhouse gas emissions. Then, considering road shoulders would lead to a 30% increase of both indicators as well, and considering road dismantling would lead to a comparable increase. Finally, the influence of materials on traffic could lead to drastic differences. However, this assumption is still controversial and should be the subject of further researches.
