Abstract
The present disclosure describes a preformed or in some cases a hot applied thermoplastic marking composition comprising a planar top surface portion and a planar bottom surface portion that are coplanar to each other, wherein said bottom surface portion is directly applied to a substrate via application of heat or pressure or both heat and pressure and wherein said top surface portion comprises an intermix that exits throughout said thermoplastic composition and includes large grit size aggregate in the range of about 8 to about 20 mesh or grit size, thereby reducing or eliminating tire tracking while also improving long-term skid resistance.
