Abstract
An inexpensive reflective paving marker, which may be used to delineate traffic lanes in construction zones, and is especially useful at night and during wet conditions, has a light weight molded plastic support structure and a reflective element composed of a thin strip of reflective polycarbonate tape. The tape is placed on a surface that is inclined to reflect incident light, such as the light from automobile headlights. The surface on which the reflective tape is mounted has a slight recess to protect the tape from the abrasive effects of traffic, such as automobile tires, to retain the reflective properties of the structure. The support structure has recesses in the bottom which provide additional grip in an adhesive, such as an epoxy or a butyl sheet, which secures the structure in place. Nails or other fasteners may also be used to secure the marker; the support structure has preformed guide holes for fasteners. The structure may also be used as a temporary or a semi-permanent reflective marker on construction barriers, machinery or other equipment, as well as being used on a roadway surface.
