System and Method for Recycling Asphalt through Radiant and Convection Heating and Simultaneous Gentle Tumbling

A system for recycling used asphalt material with radiant and convectional heat, the system comprising:

• a heating chamber, the heating chamber comprising an intake portion and an outlet portion, the heating chamber configured to retain convectional heat;
• an agitating conveyor, the agitating conveyor comprising a reception end and a discharge end, the agitating conveyor configured to enable carrying a used asphalt material from the intake portion to the outlet portion of the heating chamber, the agitating conveyor further comprising a plurality of depressions, the plurality of depressions configured to help agitate and tumble the used asphalt material while being carried to the outlet portion of the heating chamber;
• a conveyor heating member, the conveyor heating member disposed proximally to the agitating conveyor, the conveyor heating member configured to emit convectional heat of up to 750 degrees Fahrenheit,
• whereby the convectional heat from the conveyor heating member at least partially transfers to the used asphalt material;
• a radiant heating coil, the radiant heating coil configured to radiate a generally uniform convectional heat of up to 750 degrees Fahrenheit;
• at least one paddle, the at least one paddle configured to urge the used asphalt material towards the reception end of the agitating conveyor;
• at least one blower, the at least one blower configured to blow the generally uniform convectional heat radiated by the radiant heating coil towards the agitating conveyor and the at least one paddle, the at least one blower further configured to recover convectional heat from the heating chamber,
• whereby the convectional heat enables heating of the used asphalt material and the at least one paddle up to 750 degrees Fahrenheit,
• whereby the convectional heat further enables optimal thermal absorption and heat exchange with the used asphalt material,
• whereby the used asphalt material is maintained up to 750 degrees Fahrenheit while in the heating chamber,
• whereby the used asphalt material releases moisture in a controlled, uniform manner up to 750 degrees Fahrenheit;
• and
• a rejuvenating chamber, the rejuvenating chamber configured to enable reception of the used asphalt material from the discharge end of the agitating conveyor, the rejuvenating chamber further configured to enable reception of a rejuvenating composition, the rejuvenating chamber comprising a liner, the liner configured to be heated up to 750 degrees Fahrenheit,
• whereby the rejuvenating composition enhances the used asphalt material,
• whereby maintaining the used asphalt material up to 750 degrees Fahrenheit enhances absorption of the rejuvenating composition.

• providing a heating chamber for recycling a used asphalt material;
• radiating convectional heat through the heating chamber with a radiant heating coil;
• urging the used asphalt material into the heating chamber with at least one paddle;
• blowing the convectional heat radiated by the radiant heating coil towards the at least one paddle;
• heating the at least one paddle with the convectional heat radiating from the radiant heating coil;
• carrying the used asphalt material through the heating chamber with an agitating conveyor;
• blowing the convectional heat radiated by the radiant heating coil towards the agitating conveyor;
• providing a conveyor heating member for radiating convectional heat to the agitating conveyor;
• heating the agitating conveyor with the radiated convectional heat from the conveyor heating member;
• providing a rejuvenating chamber for rejuvenating the used asphalt material;
• heating the rejuvenating chamber;
• and
• mixing a rejuvenating composition with the used asphalt material.
