ASTEC Double RAP Dryer
ASTEC Double RAP Dryer

The Double RAP dryer separates the drying process from the mixing process, thereby providing a very reliable plant to be used for the purpose of recycling reclaimed asphalt pavement (RAP). The concept allows for RAP to be pre-conditioned through the external part of the Double RAP dryer, flashing off moisture in the drum, thus eliminating the problems associated with scavenger systems. With...
