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.

manufactures drums for existing equipment that can meet any specification
for installing dow bars.
Bridge Epoxy, Crack Seal, Slurry Seal and Micro

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
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
