This is a final report for a study to review and evaluate the performance of pavement marking in Colorado. The report covers the performance of materials installed transverse to the road and panel review of several long-line striping projects with higher-type pavement marking. The transverse test deck included numerous brands of both permanent and removable grades of preformed plastic, extruded thermoplastic, epoxy paint, standard alkyd traffic paint, and fast dry alkyd traffic paint. These materials were applied on both asphalt and concrete. Conclusions in the report are: (1) 100% solids epoxy paint is a durable marking material which outlasts numerous applications of standard alkyd traffic paint both on asphalt and concrete. (2) Catalyzed polyester paint seems to be unsuitable for the severe environment of Colorado Mountain interstate highways. (3) Extruded thermoplastic is a durable marking material, maintaining its retroreflectivity throughout its life when applied to asphalt. On the test deck on asphalt, the extruded thermoplastic's performance was equivalent to that of the better preformed plastics. When applied to concrete, however, extruded thermoplastic breaks up and debonds quickly. Epoxy paint is now used statewide on rural interstate lane lines. Thermoplastic is not recommended on concrete pavement.
