Heat applied thermoplastic resists degradation from oil and grease and cracking from freezing and thawing; bonds aggressively to pavement surface.
Heat-applied to dry, clean pavement, creates a chemical bond to the pavement surface. Relatively fast application and drying allows traffic to return quickly. Can be re-applied directly on worn markings. Re-application over newer thermoplastic (2 years or less) usually requires the old markings to be roughened with a grinder to create a bonding surface before reapplication.
3 to 5 years depending on traffic; excellent for winter conditions.
Higher cost per application, but more infrequent applications needed.
High traffic areas, highways, state projects.
