What is claimed is: 1. A dryer for an asphalt plant comprising: a generally cylindrical drum rotatable about its cylindrical axis having first and second ends and an interior surface; a burner having a burner head disposed at least partially within the drum for generating a flame extending outwardly from the burner from a proximal end to a distal end in a direction from the second end of the drum towards the first end of the drum and defining a combustion volume located between the first and second ends of the drum; a feeder connected to a stationary portion of the dryer for providing a recycled asphalt pavement; and, an adjustable and laterally traversable inlet for introducing the recycled asphalt pavement from the feeder into the drum at a plurality of variable positions, the adjustable and laterally traversable inlet being adjustable laterally between a first position located between the distal end of the flame and the first end of the drum and a second position located between the proximal end of the flame and the second end of the drum. 2. The dryer of claim 1, wherein the adjustable and laterally traversable inlet for introducing the recycled asphalt pavement from the feeder into the drum further includes a third position located between the proximal and distal ends of the flame and between the first and second positions of the adjustable and laterally traversable inlet. 3. The dryer of claim 1, wherein the feeder comprises a screw conveyor. 4. The dryer of claim 1, wherein the adjustable and laterally traversable inlet comprises a slidable door. 5. The dryer of claim 1, wherein the adjustable and laterally traversable inlet is adjustable over a distance of at least nine feet. 6. The dryer of claim 1, further comprising a control mechanism connected to the adjustable and laterally traversable inlet, the control mechanism controlling the position of the adjustable and laterally traversable inlet. 7. The dryer of claim 6, wherein the control mechanism is automated. 8. The dryer of claim 1, wherein the adjustable and laterally traversable inlet comprises a two-way chute. 9. The dryer of claim 1, wherein the adjustable and laterally traversable inlet comprises a three-way chute. 10. The dryer of claim 9, wherein the three-way chute comprises a pair of movable gates. 11. A dryer for an asphalt plant comprising: a generally cylindrical drum rotatable about its cylindrical axis having first and second ends and an interior surface; a movable burner having a burner head disposed at least partially within the drum for generating a flame extending outwardly from the burner from a proximal end to a distal end in a direction from the second end of the drum towards the first end of the drum and defining a combustion volume located between the first and second ends of the drum, the movable burner being movable laterally between a first position and a second position; and, a recycled asphalt pavement inlet connected to a stationary portion of the dryer for introducing a recycled asphalt pavement into the drum, wherein the recycled asphalt pavement inlet introduces the recycled asphalt pavement between the distal end of the flame and the first end of the drum when the movable burner is in the first position, and the recycled asphalt pavement inlet introduces the recycled asphalt pavement between the proximal end of the flame and the second end of the drum when the movable burner is in the second position. 12. The dryer of claim 11 wherein the movable burner includes rollers.
