Evaluation of Long-Life Pavement Markings
This report describes installation and performance of several large installations of durable pavement markings. Thermoplastic, two-component epoxy, and one brand of preformed-tape marking materials provided 4 or more years of service in longitudinal applications. Heavy snowplow damage reduced the ultimate service life of 125-mil extruded thermoplastic markings in some cases. Some premature failure resulted on the first New York State installation of two-component epoxy, and on one brand of preformed tape installed on tine-textured concrete pavement. Most installations of two-component epoxy provided good reflectivity throughout their lives. Preformed tape and thermoplastic provided good initial reflectivity, but night visibility dropped as surface beads were lost. It appears that insufficient matrix beads were included to provide good reflectivity throughout the service life of these preformed-tape and thermoplastic markings.
