PREMARK® preformed thermoplastic in-lane rumble bars provide a visual, audible and vibratory indicator to help alert drivers of special road conditions or situations that might not be apparent as well as help reduce driver risk and unsafe driving practices such as street racing.
The top layer is a preformed thermoplastic 250 mil PreMark rumble bar that is flexible and conforms to the surface which eliminates breakage associated with rigid plastic and ceramic bars. PreMark rumble bars are applied using the Flint 2000EX or Magnum Heat Torch.
