Abstract
A raised pavement marker includes a reflector assembly that is resiliently supported by a membrane, that in turn is supported by a frame. The reflector assembly includes a skirt that overlaps the membrane, thereby allowing large-area reflectors and low-angle ramp surfaces. A vent is formed between the skirt and the membrane, and this vent is resistant to clogging. Locating elements are placed on the frame of the pavement marker to assist in proper installation of the marker in a recess of a roadway, such that all portions of the frame are positioned below the surface of the roadway. Indentations allow the installer to gauge the level of adhesive in the recess.
