Abstract (en)
[origin: WO2011047705A1] The invention relates to a method and a system for producing asphalt mixture and is aimed in particular at the reuse of reclaimed asphalt. In order to achieve the reuse of up to 100% of reclaimed asphalt and to produce an asphalt mixture having the required quality, at least the drying and heating of the asphalt granulate and/or aggregates are performed in a low-oxygen atmosphere. The low-oxygen atmosphere is achieved by means of supplying low-oxygen gases having an oxygen content of at most 10%, preferably having an oxygen content up to a maximum of 5%. Advantageously, the conveying of the heated and dried asphalt granulate and/or aggregates, the ensiling, and the mixing with bitumen to form a new asphalt mixture ready for installation also occur in a low-oxygen atmosphere.
