DRUM DRYER FOR REPROCESSING RECYCLED ASPHALT PAVEMENT

摘要

An apparatus for the treatment of 100% reclaimedasphaltic pavement (RAP) is shown and described. The RAP isfirst heated in a counter flow drum which is supplied with hotcombustion gases generated by a remote low NOx burner. Thetemperature of the drum input gases is preferably around 1100degrees F and the output temperature of the gases may be 100degrees F or less greater than the input temperature of the RAP.The RAP may be heated with a microwave oven to raise the RAP toa final temperature, although this step is not absolutelynecessary in the counter flow design of this invention.
