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.

1-20. (canceled)
The temporary flexible pavement marker of claim 21, the first protective shield extending from the first side of the stand at an angle incident thereto, and the second protective shield extending from the second side of the stand at an angle incident thereto.
A temporary flexible pavement marker comprising:
- a base configured for mounting to a road surface;
- a stand flexibly extending substantially perpendicularly from the base, the stand comprising a reflective portion not covered by any protective layer removable therefrom;
- and
- a protective shield extending from the stand above the reflective portion such that when the marker is installed on the road surface, the protective shield substantially shields the reflective portion from being obscured by fluid material sprayed down onto the road surface but does not substantially obscure reflection of light from the reflective portion to vehicles traveling on the road surface after the fluid material has been sprayed down onto the road surface.
The temporary flexible pavement marker of claim 26, wherein the stand and base form either an “L” or an inverted “T”.
The temporary flexible pavement marker of claim 26 wherein the temporary flexible pavement marker comprises plastic.
The temporary flexible pavement marker of claim 28 wherein the plastic is selected from the group consisting of polyethylene, polypropylene, polyurethane, polyvinyl chloride, copolymers of polyethylene and polypropylene, and combinations thereof.
The temporary flexible pavement marker of claim 30 wherein the metal is selected from the group consisting of aluminum, spring steel, and combinations thereof.
