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.
Claims20
A temporary flexible pavement marker comprising:
- a base configured for mounting to a road surface;
- a stand flexibly extending 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 that is configured for removal therefrom to lift road treatment material away from the first reflective portion when using the temporary flexible pavement marker during repair or construction of a road, and a first non-reflective portion extending from the base to the first reflective portion;
- a first protective shield extending a protective shield width of about ½ inch to about 1 inch 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 temporary flexible pavement marker is positioned for use on a roadway surface and fluid road treatment material is sprayed down from above the temporary flexible pavement marker toward the road surface or base;
- and
- the first protective shield being configured to substantially shield the first reflective portion from the fluid road treatment material sprayed down from above the temporary flexible pavement marker toward the road surface or base 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 from the base;
- a reflective portion not covered by any protective layer configured for removal therefrom so as to lift road treatment material away from the first reflective portion when using the temporary flexible pavement marker during repair or construction of a road;
- a protective shield extending a protective shield width from the stand;
- a protective rib extending a protective rib width from the stand;
- the protective shield, protective rib, and reflective portion being proportioned so that the reflective portion is substantially protected 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 and substantially protected from backsplash of the sprayed fluid road treatment material from the road surface or base without substantially interfering with visibility of the reflective portion.
A method of providing temporary pavement markers to a road surface during repair or construction of a road and applying a road surface spray, the method comprising:
- placing a temporary flexible pavement marker upon a road surface, the flexible pavement marker including:
- a base configured for mounting to said road surface;
- a stand flexibly extending from the base, the stand comprising a reflective portion not covered by any protective layer removable therefrom so as to lift road treatment material away from the reflective portion when using the temporary flexible pavement marker during repair or construction of a road;
- and
- a protective shield extending a protective shield width from the stand above the reflective portion;
- and
- spraying fluid road treatment material at a height above the temporary pavement marker;
- and
- protecting the reflective portion of the temporary flexible pavement marker during the spraying of fluid road treatment material using the protective shield so as to maintain the reflective portion in a reflective state responsive to automobile headlights to safely delineate a traffic lane at night or other dark or limited-visibility driving conditions.
