Rotational mixing and induction heating system and method for recycling asphalt using the same

A method of manufacturing an asphaltic concrete, comprising:

• providing an asphalt, wherein the asphalt is asphaltic concrete or asphalt cement;
• providing an asphalt processing system, comprising:
• a heating drum, wherein the heating drum further comprises:
• a tubular or conal wall, encompassing an interior and having a first end and a second end;
• wherein the tubular or conal wall is composed of a magnetic material which heats upon exposure to magnetic forces;
• an input opening disposed adjacent to the first end of the tubular or conal wall;
• an output opening disposed adjacent to the second end of the tubular or conal wall;
• a heating system, comprising:
• at least a first heating source, wherein the at least first heating source is disposed on an outside of the tubular or conal wall and disposed to direct heat to the tubular or conal wall;
• and
• a drive system in communication with the heating drum which rotates rotate the heating drum;
• rotating the heating drum about a central axis;
• activating the heating system to apply heat to the tubular or conal wall of the heating drum;
• placing an asphaltic concrete mix into the heating drum, wherein the tubular or conal wall of the heating drum is heated to between 300° F. and 750° F.;
• moving the asphaltic concrete mix along the heating drum, wherein the asphaltic concrete mix is mixed while moving;
• heating the asphaltic concrete mix to between 300° F. and 350° F. to form a heated mix;
• and
• expelling the heated mix from the asphalt processing system.
