Apparatus and method for applying temporary raised pavement markers (TRPM) to roadway surfaces comprises pri-mary 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 ac-cordance 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 por-tion 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 appli-cator 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.
