A screw conveyor in which mixing and flow-directing paddles are selectively adjustable for use on a wide variety of materials having dissimilar flow characteristics. The adjustable paddles are advantageously applied to a screw, or auger, conveyor of an asphalt paving machine to convey a sufficient amount of unsegregated paving material beneath a center drive case or other problem distribution area.

Screw conveyor

A paving material distribution system for uniformly distributing a layer of paving material includes a containment member that is slidably mounted on the rear frame of a paving machine. A first means for conveying paving material laterally with respect to the direction of travel of the paving machine is positioned at a preselected distance from the containment member. Power means are also included to controllably, simultaneously move the containment member and the first means in a substantially vertical direction.
