This paper presents an overview of recycling in road infrastructure based on the OFRIR project, OFRIR being the acronym of Observatoire Français du Recyclage dans les Infrastructures Routières. The OFRIR project has been based on a literature review of recycling in road framework in France since 1980, considering both environmental, geotechnical road building and service requirements. The review is presented in an internet site (http://ofrir.lcpc.fr, mail : [e-mail]) for road national actors aiming at proposing classified, summarized and validated information in order to help recycling decisions. Besides, part of the delivered information is attached to a geographical presentation in order to highlight local resources and practice. Besides, LCPC and French technical network of road public ministry, BRGM (French Geological and mining organism) and INERIS (French Institute for risk assessment) also significantly contributed to this project supported by METLTM/DRAST and DR (Ministry of Transport and Construction/Scientifical office and Road direction), by MEDD/DPPR (Ministry of environment and sustainable development/ Pollution and risk direction), by ADEME (Energy and Environment Agengy) and finally by SETRA (Road and highway technical studies office). The Internet site opened at the beginning of august 2003 and is currently being implemented with new data until 2006. Actually about fifteen products are presented, among which civil engineering by-products and other industrial by-products have been considered. A network of a hundred club members has also been developed. These members exchange data and documents that can be proposed on-line within the site. The club members are at present mainly French actors although some European actors have already decided to join the club members to contribute to this common knowledge. This paper gives a general presentation of the actual available data. Then, a discussion based on a global analysis of collected data is presented. In particular, product peculiarities depending on their origin, that is, either natural materials with low characteristics, road waste or industrial waste, are examined.
