A sphalt recycling technology (hereinafter called “the Technology”) is a method to repair roads at lower cost and with lower environmental impact than conventional methods. The technology can reduce the use of new pavement materials by recycling reclaimed asphalt pavement (hereinafter called the "RAP") which is generated when roads are repaired, for producing recycled asphalt
