ABSTRACT:
Apparatus and method of forming a durable and immediately reflective line rking on roadways are described. The method includes melting a thermoplastic resinous material, projecting a continuous stream of the melted material onto the roadway in a line and simultaneously (a) projecting a first continuous stream of glass beads into the stream of thermoplastic material as the stream is being applied to the roadway; and (b) dropping a second stream of glass beads onto the top of the thermoplastic/glass bead line immediately after the line is applied to a roadway. The equipment includes a multisection melting tank for the thermoplastic material having a temperature gradient across the different sections, a heated holding tank separably connected to the melting tank, a spray unit for spraying the thermoplastic material, and means for simultaneously projecting glass beads into the liquid marking material as it is being applied and for dropping glass beads onto the applied line after it is applied.
