Abstract
An apparatus and method for manufacture of asphaltic pavement from recycled asphalt pavement (RAP) and virgin rock and asphaltic materials is shown and described. This method utilizes efficient and controlled heat from a recirculating air impingement air dryer for heating of the RAP to a first temperature prior to the RAP being mixed with high temperature rock which is supplied from a rotating drum heater. The mixture of rock and RAP may comprise as much as 80% RAP because the RAP is preheated piror to the RAP rock mixing step.
