An installation of five longitudinal grooved stripes combined with a recessed corner-cube reflector has withstood a full winter of exposure to traffic and snowplowing on a four lane highway without significant loss or damage and has continued to provide wet-night visibility up to the present time. It is used as a supplement to conventional beaded paint strips which provide daytime and dry night visibility. Observations on the wet night visibility and durability of this system are continuing. A more extensive installation of these reflector-groove combinations has been made on 1-1/3 miles of asphaltic and portland cement concrete pavement for a full year's evaluation. The reflector-groove combination is the most promising of several types of grooved striping which have been studied in two field installations in an effort to develop a snowplowable system exhibiting greater wet-night visibility than conventional beaded traffic paints.
