Evaluation Of Snowplowable Marker Installations, Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
The first large-scale contracts for the installation of snowplowable markers were awarded in 1984 and 1985. Stimsonite 96 and recessed markers were installed. The objective of this study was to evaluate the performance of the installations. Durability and reflectivity results show that both the recessed markers and Stimsonite 96 markers have performed effectively as snowplowable markers. The recessed markers should continue to be used only on four-lane highways constructed to high geometric standards with the Stimsonite 96 markers installed on the majority of highways.

Evaluation Of Durable Crosswalk And Stopbar Marking Materials, Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
The objective of this study was to find the most cost-effective durable marking material to provide long-lasting stop bars and crossbars. Three materials were tested: 1) 3M Stamark tape, 2) Prismo preformed tape, and 3) extruded thermoplastic (hydrocarbon and alkyd). The various test installations were in place for between 6 and 30 months.
The alkyd-resin thermoplastic material was found to be the most cost-effective I material. The preformed tapes cost two to three times as much as the thermoplastic material while not providing as durable a material when used in this application.The alkyd-resin material maintained its appearance better than the …
Evaluation Of Durable Lane Delineation Materials, Kenneth R. Agent, Jerry G. Pigman
Evaluation Of Durable Lane Delineation Materials, Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
The objective of the study was to evaluate the cost-effectiveness of available marking materials by means of field tests and to make recommendations concerning the optimum lane delineation materials based on these tests. Materials tested include 100-percent solid epoxy paint, polyester paint, extruded thermoplastic, 3M Stamark tape, 3M Bisymmetric tape, EPOFLEX, solvent epoxy paint, chlorinated rubber traffic paint, and alkyd traffic paint. The test installations have been in place up to four years. The evaluation concerned the durability, reflectivity, and appearance of the materials. Based on current data, expanded use is warranted for 1) polyester paint on lower-volume asphaltic concrete …
