SAFETY ROADWAY DELINEATOR EFFECTIVE DURING RAINY NIGHT-TIME DRIVING CONDITIONS AND METHOD OF MAKING THE SAME

摘要

A safety roadway delineator includes one or moreelongate recessed marker surfaces which are coated with areflective material, preferably a retroreflective materialsuch as reflective glass beads. The recessed marker surfacesare vertical or at least inclined to the horizontal to insurewater run-off and are formed either directly in cast-in-placeconcrete roadway members or in pre-cast polymer concretefacing panels which are attached to the cast-in-placeconcrete roadway members. The roadway delineator issubstantially continuously protected from normal wear andreliably exhibits reflectivity..both under dry and rainyweather conditions.
