Pavement Maintenance


Aftermarket Drum Manufacturing

Bump Grinding and IRI Improvement - Keystone manufactures drums for existing equipment and complete skid steer attachments for shaving bumps and other rough areas on pavement to increase IRI numbers. Keystone's Flatliner skid steer attachment is perfect for correcting new pavements and is an ideal maintenance tool for aging pavements.

Longitudinal Joint Repair - Keystone's "V-Head" drum system provides a cost effective way of repairing joints on both concrete and asphalt roads before overlays.

Load Transfer/Dow Bar Retrofit - Keystone manufactures drums for existing equipment that can meet any specification for installing dow bars.

Bridge Epoxy, Crack Seal, Slurry Seal and Micro Surfacing Removal - Keystone developed Flat Tooth Technology for when any spacing, including micro milling, is too large. The Flat Tooth System cuts 100% of the pavement's surface and is ideal for removing bridge epoxy, crack seal, slurry seal and micro surfacing.

Micro Milling and Fine Milling - Keystone can design and manufacture to meet any micro milling or fine milling specification. Keystone offers a large variety of block systems including the Wedge Lock System which is the only Quick-Change system to give contractors the ability to standard mill and micro mill with the same drum.

Block and Tooling Systems

Wedge Lock Quick-Change System

  • Interchangeable blocks for different cutting applications transform a standard milling drum into a micro-mill drum, simply change the holders to achieve a 7.5mm/.3” and even a 5mm/.2” surface pattern
  • Replaceable blocks are positioned on the wear side of the flighting which protects the flighting against wear
  • No threaded parts are welded to the drum providing a longer lasting drum
  • Continuous wrap design provides superior strength
  • Wedge Lock Systems with over 18,000 hours are still in use today

Flat Tooth System
 

 

  • Can serve as a substitute for a diamond ground surface
  • Leaves a flat and smooth surface pattern without ridges or grooves
  • The bit’s design eliminates surface damage seen with conical milling bits
  • Completely machined bit and block insures uniform
  • surface pattern
  • The compound taper locking system pulls the bit in and down for precise alignment
