Temporary reusable retroreflective raised pavement marker
Abstract:
The present invention incorporates to a new temporary, reusable, retroreflective, raised pavement marker design. The pavement marker utilizes a water soluble, adhesive embedded in a fibrous base material for application to the pavement. This temporary adhesion method allows the pavement marker to be reused after removal from the pavement. The semispherical shape of the marker provides increased lateral stability. The recesses on the top surface of the marker protect the retroreflective microspheres from loss of retrorefectivity from vehicular abrasion. The round shape also allows the marker to be used to form arrows and other pavement markings.
