Title:	Tunnel excavation material - high value raw material / Tunnelausbruchmaterial - hochwertiger Rohstoff
Abstract:	A project called “Recycling of Tunnel Excavation Material” has been running since November 2008, supported by the Austrian Research Promotion Agency (FFG) and eminent Austrian client organisations and companies engaged in tunnelling and hydropower station construction, to investigate the possible recycling of tunnel excavation material at eleven selected Austrian tunnel and hydropower projects. This is intended to demonstrate economical and environmentally positive recycling. Test strategies are also to be developed for the evaluation of the reusability of tunnel excavation material from the point of view of construction management and economics, both for the individual projects and also relevant to the main lithologies likely to be encountered in Austrian tunnels. Seit November 2008 wird in einem von der Forschungsförderungsgesellschaft (FFG) und namhaften Auftraggebern und Baufirmen des österreichischen Kraftwerks- und Tunnelbaus unterstützten Forschungsprojekt “Recycling von Tunnelausbruchmaterial” die mögliche Wiederverwertung von Ausbruchmaterial an elf ausgewählten österreichischen Tunnel- und Kraftwerksprojekten der Zukunft untersucht. Eine wirtschaftliche und umweltschonende Wiederverwertung soll nachgewiesen werden. Weiters werden für die einzelnen Projekte und die in Österreich bei Tunnelausbrüchen zu erwartenden Hauptlithologien Versuchsstrategien zur Beurteilung der Wiederverwendbarkeit von Tunnelausbruchmaterial aus baubetrieblicher und bauwirtschaftlicher Sicht ermittelt.
