Abstract
A system for controlling the production of an asphalt mix. The preferred system comprises a recycled asphalt pavement source, a recycled asphalt pavement sensor, a liquid asphalt cement source, a liquid asphalt cement meter, and a controller. The recycled asphalt pavement sensor communicates the amount of recycled liquid asphalt cement and the amount of RAP moisture contained in the amount of recycled asphalt pavement to the controller, the liquid asphalt cement meter communicates the amount of liquid asphalt cement provided by the liquid asphalt cement source to the controller, and the controller controls the amount of recycled asphalt pavement provided by the recycled asphalt pavement source and the amount of the liquid asphalt cement provided by the liquid asphalt cement source. A method comprising controlling the amount of recycled asphalt pavement and the amount of liquid asphalt cement provided to the asphalt mix substantially continuously and substantially in real time.
