HTC
Self-contained patching system
 The
HTC Patcher 48 turns a truck into a
self-contained production patching system. The patcher mounts directly to
any truck, using either existing plow-hitch points and hydraulic control

Cleat America
Asphalt mini-plant/recycler
Cleat America’s Astencook Super-043 portable asphalt
mini-plant/recycler uses a patented process, Dynamic Batch Recycling, to
recycle asphalt spoil fast. According to the company, over 95% of the
asphalt content is retained and the air void percentage is restored to plant
specification, which is essential for compaction, strength, and long life.
The process can be manipulated to produce finer or coarser mixes. Recycling
takes approximately 20 minutes per batch. The unit is compact,
fuel-efficient, and operates without visible emissions or appreciable noise.

Duraco Industries
Injection patching machine
 Duraco Industries’ DuraPatcher model 125DJT repairs
streets and highways using injection. The injection type repair is made by

Perma-Patch
Cold patch repair material
 Perma-Patch’s blend of pressure-sensitive plastics,
chemicals, modified asphalt, and aggregate can be used to patch potholes in
temperatures ranging from -10 to over 100 degrees F, rain or shine. No
special equipment is needed to apply the material and traffic is not
shutdown for extended periods of time. Crews spread the material directly
from the 60-pound bag and rake it out to a depth slightly above the
surrounding pavement. Water and debris need not be removed prior to
application. After installation, the repair is compacted with a vehicle
tire, hand tamper, portable plate compactor, or Jumping Jack. According to
the company, the patch will not shrink, thereby forming a water tight seal
with the existing pavement and preventing further damage.

Crafco
Spray injection patcher
 Crafco says its Magnum Spray Injection Patcher
repairs a wide variety of pavement conditions including potholes,
deteriorated shoulders, utility cuts, fissures, and alligator cracks. The
patcher’s integrated operation cleans the area to be repaired, applies a
tack coat, coats the aggregate with asphalt emulsion, and then applies the
mixture, all in one continuous operation. Using high-velocity air, the
coated aggregate material is compacted during application, leaving virtually
no voids in the final repair and making a long-lasting patch, according to
the company.
The Magnum features a maintenance-free emulsion feed
line and a machined aluminum application nozzle that contains an internal
pressurized spray ring that the company says assures 100% aggregate coating.
The unit can place over 7 tons per hour.

Unique Paving Materials
Concrete patching material
 A new concrete patching material from Unique Paving
Materials is specially designed for patching, repair, and restoration of
worn or damaged concrete structures and surfaces. CPM is a high-strength,
rapid-developing, commercial-grade concrete patch that offers resistance to
chlorides and acids. The company says the material can withstand high
freeze-thaw conditions, allows minimal chloride penetration, and has high
compressive and shear/bond strength without the need for an additional
bonding agent. A 2-inch layer of material begins to set up within 20 minutes
of use, and the area can be reopened to traffic in as little as 45 minutes
to an hour. For repairs deeper than 6 inches, a second layer can be applied
after 30 minutes. The repaired surface is ready for paint after 24 hours.

Schwarze Industries
Velocity-filled asphalt patcher
 Schwarze Industries’ says their Roadpatcher provides
the end user with a lower cost of operation, a decrease in liability
exposure, and a 92.8% compaction rate with the operator never having to
leave the cab. Aggregate material is controlled through a positive-flow

cleans the pothole, applies a tack asphalt emulsion, fills and compacts the
hole with patching material, and then tops the repair with a dry coat so
that the road can be opened to traffic immediately. All these actions are
controlled from the safety of the cab. A line of trailer-mounted
self-contained patchers are also available.

Bergkamp
Flameless pothole patcher
 Bergkamp’s FP5 Flameless Pothole Patcher’s insulated
5.1-square-yard electric heated hopper keeps asphalt at a constant
temperature and pliable for an extended period of time. The material chute,
spoils bins, and tools are easily accessible from the back or from curbside
so the operator doesn’t have to step into traffic. A hydraulic lift platform
lowers the pavement breaker and plate compactor from its transport position
on the patching machine to reduce the possibility of back injury. The system
can be plugged into an external power source to keep material warm overnight
or over a weekend, reducing material waste and allowing the unit to be
filled at the end of the day. Directional arrow lights at the back of the
truck safely signal approaching traffic of the road work.
The FP5 is available in both truck-mounted and
trailer-mounted versions. The truck-mounted version is a one-piece unit that
mounts easily on a short-wheel-base 35,000 GVW single-axle truck for good
maneuverability. A large working deck at the front of the unit provides
access to the deck-mounted storage tanks and hopper. The trailer-mounted
version has the same features but is run by an onboard generator and can be
pulled by an air-brake equipped truck.
