Thermoplastic is a hydrocarbon-based product that increases durability and longevity of road markings. It does this by physically bonding to the aggregates in the blacktop and by chemically bonding to the hydrocarbons in the asphalt emulsion. Typically, it is used for transverse markings that receive the most wear from motor vehicles, such as stop bars, crosswalks, and arrows. For most Municipal Capital Projects, thermoplastic is now being specified for longitudinal markings as it can last up to 7 years before requiring maintenance.
