A method for producing a pelletized pavement marking mixture includes selecting an appropriate thermoplastic binder that is a solid at ambient temperatures and mixing the appropriate thermoplastic binder in a mixing vessel with a plasticizer and a filler to form a substantially evenly blended homogeneous pavement marking mixture by blending the pavement marking mixture for a period sufficient to substantially evenly distribute the plasticizer and the filler with the thermoplastic resin; transferring the substantially evenly blended pavement marking mixture from the mixing vessel to a compression pelletizer; and pelletizing the substantially evenly blended pavement marking mixture by compression. A pavement marking mixture consists of pellets, each of which consists of a substantially evenly blend of a thermoplastic binder, a plasticizer, and a filler. The method for making a pelletized pavement marking mixture can be extended by adding a pigment and retroreflective particles to the pavement marking mixture.
