Beschreibung
Zusammenfassung:	A recycled asphalt product (RAP) drying apparatus comprising a three-zone counterflow RAP dryer and a duct system to recycle essentially all of the hot gases back through the system. The three-zone RAP dryer has a combustion zone at one end, a drying zone at the other end, and a buffer zone between the combustion and drying zones. A RAP inlet to introduce RAP into the dryer is included at one end of the drying zone, and a RAP outlet to remove RAP from the dryer is included at the other end of the drying zone. A duct pathway routes hot air from the drying zone back to the buffer zone so that hot air may be recycled through the apparatus.
