Abstract
Apparatus for removing temporary raised pavement markers (TRPM) from roadway surfaces comprises a platform, and a plurality of cutter blades rotatably disposed beneath the platform for encountering and severing the upstanding vertical reflective portions of the temporary raised pavement markers (TRPM). The cutter blades are driven by a motor mounted upon an upper surface portion of the platform, and a blower is also mounted upon the upper surface portion of the platform. An upstream intake duct, fluidically connected to the intake side of the blower, passes through a rear end portion of the platform so as to be fluidically connected to the underside of the platform, and in this manner, the severed upper reflective portions of the temporary raised pavement markers (TRPM) may be removed from the roadway surface and conveyed to a suitable debris collection bag.
