Evaluation Of Epoxy Thermoplastic Pavement Marking Material, Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
The objective of this study was to evaluate the field performance of epoxy thermoplastic (ETP) as a pavement marking material and to compare it to a control marking material, which was alkyd traffic paint. A test installation of ETP along with the regular traffic paint was placed on KY 841 in Jefferson County and evaluated over an 18-month period. Data collection consisted of daytime observations and rating of the material's appearance and durability and nighttime observations and rating of its nighttime visibility. Reflectivity measurements were also collected using a portable retroreflectometer.
The appearance (color) of the ETP remained good over …

Evaluation Of Construction-Zone Pavement Marking Materials, Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
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.
