Preformed Reflective Line Marking for Roadways and Associated Methods Thereof

A method for installing a preformed thermoplastic roadway line marking, the method comprising the steps of:

• providing and attaching a preformed thermoplastic substrate layer to a roadway by heating the preformed thermoplastic substrate layer to a liquid state such that the preformed thermoplastic substrate layer has a morphed shape;
• providing and contacting a preformed thermoplastic upper layer with the preformed thermoplastic substrate layer, the preformed thermoplastic upper layer including a surface area having a plurality of spaced slits, wherein the slits penetrate through an entire cross-sectional thickness of the preformed thermoplastic upper layer;
• applying a downward external force on the preformed thermoplastic upper layer such that the slits are in fluid communication with the liquid state of the preformed thermoplastic substrate layer;
• and
• fixedly locking the preformed thermoplastic upper layer to the preformed thermoplastic substrate layer and maintaining the preformed thermoplastic upper layer at a substantially stable position relative to the preformed thermoplastic substrate layer by at least partially displacing upwardly the morphed shape of the preformed thermoplastic substrate layer through the slits and thereby disposing the morphed shape of the preformed thermoplastic substrate layer on the preformed thermoplastic upper layer.
