Improved Cutter Drum Design

Roadtec introduces improvements to its line of cold planer cutter drums.

  • The drum end ring configuration has been redesigned for better match-cutting and increased tool life; the lacing pattern was adjusted to provide a better texture on the milled surface as well as a more balanced impact when the cutting tools strike the surface; this design has been modified with the goal to provide 3,000 hours of service of the tool base and cutter drum's components manufactured at Roadtec
  • The improved pattern the new drum design is capable of producing will enhance bonding of the new asphalt layer to the existing base and can also aid in the longevity and higher smoothness of the pavement because over time and with traffic, a rough milled surface will show through the asphalt on a typical thin lift paving job
