The purpose of the evaluation was to determine the feasibility of using raised pavement markers placed in pavement grooves as a guidance aid for motorists during nighttime inclement weather conditions. Emphasis was on the visibility and durability characteristics of the markers as influenced by the method of placing them in pavement grooves. It was concluded that the method employed for placing the raised markers in the pavement is feasible for use as a means of protecting the marker from snowplow damage while providing guidance for motorists. However, it is recommended that this method of placing raised pavement markers in grooves not be used for centerline delineation until a method of installation is available which will decrease the cost of installing the markers.
