Patent ID: 8882899

Claim:
Method for producing asphalt mixture, comprising: heating and drying recovered asphalt as asphalt granulate and/or new material in the form of aggregates in drum devices together or separately; and subsequently mixing the heated and dried asphalt and/or aggregates in a mixing device with bitumen to form an incorporation-ready asphalt mixture, wherein the mixing of the heated and dried asphalt granulate and/or the aggregates is carried out in a low oxygen atmosphere, in which the oxygen content is maximum 10%, wherein the asphalt granulate and/or the aggregates is/are dried and heated in the drum devices utilizing low oxygen gases having a temperature in the range of from 500 to 1000° C. and subsequently conveyed to the mixing device and the conveyance and mixing are carried out in a low oxygen atmosphere, whereby cold, low oxygen gases having a temperature in the range of from approximately 20 to approximately 150° C. or cooled, low oxygen gases having a temperature in the range of from approximately 150 to approximately 300° C. are fed to a conveying device and the mixing device, and siloing of the heated and dried asphalt granulate and/or aggregates before the mixing with the bitumen and/or siloing of the incorporation-ready asphalt mixture in a low oxygen atmosphere is/are carried out.
