Abstract

An apparatus for oriented application of a raised pavement marker to a roadway surface includes a reservoir of liquid adhesive; means for discharging a portion of liquid adhesive to form a deposit on the roadway, means for dispensing a raised pavement marker onto the top of the adhesive deposit; and means for aligning the marker at a desired orientation. The apparatus may also include a magazine for storing and sequentially delivering a plurality of raised pavement markers to the means for dispensing. The magazine has inclined walls which accommodate markers with rounded tops and prevent twisting or jamming of the markers.
