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

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 …
