Abstract
A temporary flexible pavement marker comprising a base, a stand and a protective shield wherein at least part of the stand is reflective and the protective shield is configured to prevent materials sprayed down upon the temporary flexible pavement marker from obscuring the reflective part of the stand may be employed in the construction or repair of roads. Since the protective shield prevents asphalt from obscuring the reflective part of the stand during spraying operations there is no need for a technician to remove a protective layer from the markers after a spraying operation.
