摘要： A safety roadway delineator includes one or more elongate recessed marker surfaces which are coated with a reflective material, preferably a retroreflective material such as reflective glass beads. The recessed marker surfaces are vertical or at least inclined to the horizontal to insure water run-off and are formed either directly in cast-in-place concrete roadway members or in pre-cast polymer concrete facing panels which are attached to the cast-in-place concrete roadway members. The roadway delineator is substantially continuously protected from normal wear and reliably exhibits reflectivity both under dry and rainy weather conditions.
