Abstract: Systems and methods are provided for use with a thermoplastic road marking system (e.g., paint truck). The systems and methods control an insertion or replenishment rate of unmelted thermoplastic paint feed stock into a thermoplastic melter based, at least in part, on the rate that thermoplastic melt is being applied to a marking surface. By substantially matching the replenishment rate into the thermoplastic melter with the application rate, thermal variance within the thermoplastic melter is reduced, which improves the consistency of marking lines applied to surfaces.
