The objectives of this study were to evaluate available foil-back and removable tapes as well as construction-zone raised pavement markers and to recommend materials that should be included on approved lists for use by the Kentucky Department of Highways. Tapes and markers were placed on transverse test sections and the reflectivity, durability, and appearance were observed.

Tapes to be included on the approved lists for foil-back and removable tapes were recommended. Tapes manufactured by 3M, Flex-O-Lite, Cataphote, and Swarolite were included on the list of acceptable foil-back tapes. Recommended removable tapes were the 3M and Cataphote removable tapes. Stimsonite 66 and Flex-O-Lite construction-zone markers were included on the approved list for construction-zone raised pavement markers.

More specific guidelines were developed to use in future evaluations of construction-zone preformed tape and markers.
