Abstract
An apparatus for controlling the angular velocity and slope angle of a hot mix asphalt drum as a function of the temperature gradient across the drum outlet. Uneven gas outlet temperature indicates that the veil of RAP (Recycled Asphalt Pavement) in the drum is insufficient. The veil is increased by increasing drum speed. The complete recycled asphalt pavement hot mix asphalt plant uses uneven gas outlet temperatures to change drum operating parameters.
