Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises primary and auxiliary conveyors wherein an upstream end portion of the primary conveyor is able to extend, for example, over the rear bed portion of a roadwork truck so as to permit an operator, stationed upon the bed portion of the truck, to deposit pavement markers upon the primary conveyor. In accordance with a first embodiment of the invention, a slide mechanism is disposed adjacent to a downstream end portion of the primary conveyor and adjacent to an upstream end portion of the auxiliary conveyor for transferring pavement markers from the primary conveyor to the auxiliary conveyor when the absence of a pavement marker upon the auxiliary conveyor is detected. When pavement markers are present upon both conveyors, the pavement markers are conducted to applicator mechanisms for application to the roadway surface. A second embodiment of the invention comprises the use of a pair of wheel applicators for applying the temporary raised pavement markers (TRPMS) to the roadway surfaces.
