Patent abstract
A method of making hot mix asphalt using recycled asphalt in which tertiary air is mixed with products of combustion at an exit of a refractory-lined chamber to produce hot controlled temperature process air, the temperature of the tertiary air being increased while the temperature of the products of combustion is decreased to adjust a temperature of the hot controlled temperature process air. Particles of the recycled asphalt are heated by exposing the particles to the hot controlled temperature process air in the rotary counter-flow dryer and mixer and moisture is removed from the recycled asphalt with the hot controlled temperature process air.
