Abstract

The invention relates to a method and a plant for producing asphalt mixture and is di-rected in particular to the recycling of recovered asphalt. In order to achieve recycling of up to 100% recovered asphalt and to produce an asphalt mixture with the required qual¬ity, it is provided according to the invention that at least the drying and heating of the asphalt granulate and/or aggregates are carried out in a low oxygen atmosphere. The low oxygen atmosphere is achieved by supplying low oxygen gases with an oxygen content of maximum 10%, preferably with an oxygen content of maximum 5%. The con¬veyance of the heated and dried asphalt granulate and/or aggregates, the siloing and mixing with bitumen to form a new, incorporation-ready asphalt mixture also usefully take place in a low oxygen atmosphere.
