A pelletized road marking composition includes a binder mixture, a filler mixture and bentonite clay. The binder mixture includes at least one alkyd ester, at least one wax, at least one ethylene copolymer, and at least one plasticizer. The filler mixture includes at least one coloring additive, reflective elements, and at least one inert inorganic filler. The components of the road marking composition are mixed and melted and processed into pellets. The bentonite clay added to the composition prevents the pellets from clumping when stored at elevated temperatures.
