    Patent number: 4957434
    Abstract: A method of heating reclaimed asphalt paving is shown and described. An air sorter removes fine materials from the reclaimed asphalt paving, and an air circulating dryer which utilizes high velocity air impingement, removes the moisture from the material. A conventional combustion heating tunnel is used to raise the temperature of the material to a first desired temperature and a microwave heating tunnel is used to raise the temperature to a final desired temperature.
