ABSTRACT
Future transportation infrastructure projects will include significant underground sections. These projects will result in huge quantities of excavated materials that could not be entirely deposited on landfill. The use of excavated materials during underground work will contribute to preserve natural resources and to reduce the impacts related to the transport of materials over long distances. Thus, alternative solutions can be found by producing for example new eco-designed building materials. The owner is responsible for the management of excavated materials. It is in charge of defining a specific policy and must specify the requirements for reuse and recycling. To help it, three general scenarios are described and a management method is proposed, from the project definition study stage to the construction phase. The role of each project stakeholder is detailed. Finally, some of the main aspects are illustrated by case studies.
