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 removal of a protective layer from the markers after a spraying operation.
Claims14
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 having a first side, the first side of the stand comprising a first reflective portion not covered by any protective layer removable therefrom and a first non-reflective portion extending from the base to the first reflective portion;
- a first protective shield extending a protective shield width from the first side of the stand above the first reflective portion to substantially shield the first reflective portion from being obscured by fluid road treatment material when the fluid road treatment material is sprayed down from above the protective shield toward the road surface or base;
- a first protective rib extending a protective rib width from the first side of the stand below the first reflective portion, the first protective rib width being shorter than the first protective shield width, the first protective rib width extending to substantially shield the first reflective portion from being obscured by backsplash of the sprayed fluid road treatment material from the road surface or base;
- the protective shield width being from ½ inch to 1 inch for a 4-inch long by 2-inch height temporary pavement marker;
- and
- the reflective portion being substantially protected from both the fluid road treatment material when sprayed down from above the first protective shield toward the road surface or base and also from backsplash of the sprayed fluid road treatment material without substantially interfering with visibility of the first reflective portion.

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 non-reflective portion;
- and
- a protective shield extending a protective shield width from the stand above the reflective portion, the protective shield angled downwards towards the ground to substantially shield the reflective portion from fluid road treatment material when the fluid road treatment material is sprayed down from above the protective shield toward the road surface or base while still providing visibility to oncoming traffic when the pavement marker is positioned on said road surface.

- wherein the base is about one inch wide and about four inches long, the stand is about four inches long, the first protective shield width is about one-half inch;
- and
- the reflective portion being substantially protected from both the fluid road treatment material when sprayed down from above the first protective shield toward the road surface or base and also from backsplash of the sprayed fluid road treatment material without substantially interfering with visibility of the first reflective portion.
