This study involved the field testing of four types of pavement tapes, all manufactured by the 3M Company. The tapes evaluated included Scotchlane, Stamark Removable, Stamark, and an experimental tape. The experimental tape had an extremely high initial reflectivity but poor durability, which would preclude use in its present form. The remaining tapes exhibited good durability when used as lanelines and edgelines. The Scotchlane tape exhibited the best long-term reflectivity. The Stamark tape does not provide sufficient reflectivity and could not be used in areas where delineation would be critical. The Stamark Removable tape was easily removed manually after one or more years of field testing.
