It should be noted that in addition to environmental concerns, technical and economic aspects, statutory requirements also significantly affect the handling of tunnel excavation material. The project client as well as the construction industry must deal with all these challenges, in order to achieve a maximum utilisation level of tunnel excavation material in the future. A not insignificant portion of the annual demand for raw materials in Austria can already be met by the use of tunnel excavation.
The main developments in the EU DRAGON research project relate to the online analysis of physical and chemical parameters, developments in the areas of materials management and processing as well as the development of a tunnel excavation material database.
The DRAGON project is coordinated by the Mining University of Leoben; Industry partners are B+G AG – Betontechnologie und Materialbewirtschaftung, Herrenknecht AG, Indutech Instruments GmbH, Jacques Burdin Ingenieur Conseil, PE Northwest Europe Limited and PORR Bau GmbH, which should ensure a practical implementation.
