Abstract
This work takes places in the context of the creation of a new research team at LCPC, performing studies in the field of sustainable development applied to roads. The present on-going projects - a recycling road works using hot-mix reclaimed asphalt pavement and a data base on material recycling in roads - are leading to the collection of significant environmental data. These projects also include the application of LCA methodology to roads, and display a territorial approach. Finally the research work is focused on a modular analysis of road infrastructures, which should be extended in the future to both economical and social spheres.
