Thermoplastic is a considered a longlife material that is heated to a molten state (400 to 440 degrees) and then applied to the pavement by either an extrusion or spray method.  It was initially designed for installation on asphalt surfaces so that it could “melt into” the asphalt, which is also hot applied, hence creating a good solid bond when cooled.  It can be installed on concrete surfaces with the use of a primer sealer but it is not recommended for this use.  Thermoplastic markings are applied in various thicknesses; extrude 90 mil and 120 mil and spray 40 to 90 mil. Thermoplastic markings can be applied by truck-mounted applicators or by handliners.  The hand liners are used for symbol, legend and stopbar installation.  Most linear applications are done by truck (longline) installation.

Thermoplastic has a glass bead intermix which allows the product to maintain reflectivity as the line wears over time.  This is in addition to the drop on glass beads that are applied at installation for initial reflectivity.
