    Softening the old road surface with radiant heat produced by ceramic emitters.
  2. 2.
    Loosening a thin layer of old material with air-bag mounted scarifiers.
  3. 3.
    Mixing new and old material with liquid asphalt in a pug mill.
  4. 4.
    Laying and compacting the new road surface with a vibratory screed.
  5. 5.
    Completing the softening, loosening, mixing, laying and compacting operations in one continuous operation.
