Abstract (en)
A method of heating asphalt-containing materials in a device with the aid of combustion gases or heated air respectively, whereby the asphalt-contaioing materials are indirectly heated with the aid of combuston gases, the combustion gases being passed in the same direction through the device as the asphalt-containing materials, whilst the asphalt-containing materials are simultaneously brought into direct contact with combustion gases which have cooled in the meantime as a result of the indirect heating to below about 450 DEG C and which are passed also in the same direction as the asphalt-containing materials through the device.
