Repairing asphalt with Kasi infrared equipment will cut labor and material
costs in half, and enables road crews to perform ultra-clean patching with
no seams left behind for water and ice to get back under the repair. And
the repairs can be made year round.
Potholes, trench cuts and other asphalt repairs are the bane of public
works managers and road crews . . . ubiquitous, time-consuming, expensive
to repair, tie up traffic and are hazardous to passenger cars, trucks,
cyclists, skaters and pedestrians.
Now a new infrared asphalt repair technology enables city, county and state
road crews to save tons of time, material and labor costs in repairing
hazardous potholes, alligator cracking, failed utility cuts and other surface
defects that plague their asphalt streets and parking lots - year round.
The infrared technique also provides superior repairs to roads, parking lots
and driveways at savings of up to two-thirds the cost of conventional methods.
As opposed to conventional repair, which requires the removal of old asphalt
from a damaged site and its replacement with new asphalt, the new infrared
technology expedites repair by heating, fusing, and compacting recycled asphalt,
saving equipment, labor, and new material in the process.
"The infrared system has enhanced our operations by reducing repair time and
allowing us to repair larger surface areas," says Steve Ortega, Street
Operations Foreman Commerce City, CO (just north of Denver). "It also does a
better repair then just filling a pothole or alligator cracking with new
Ortega adds that using the city's new asphalt repairing technology, purchased
from Kasi Infrared Corp. (Newport, NH), his road crew can load up a couple of
tons of asphalt and be busy all day. He adds that, in addition to saving time,
the new infrared repair technology enables his crew to recycle a substantial
portion of the old asphalt, saving on materials costs as well.
"In the past we would take four or five tons out to the streets. But now, due
to recycling, we just take out about a ton and a half or two tons at the most.
That's because you're able to rejuvenate and reuse much of the asphalt being
Although not a large community, Ortega says Commerce City is conscientious about
keeping the 700 or so lane-miles of its roadways in good condition.
While public safety from road hazards is always a high priority, exposure to
liability claims may also be important to many local governments, particularly
those who are self insured.
The city of Moline, IL, relies on residents and drivers to provide updates on
potholes and other road hazards. During the wintertime the city offers a $50
reward to the person who reports the largest pothole.
"We take potholes and other types of failures very seriously," Ortega says.
"It doesn't take much to create a hazard. It could be cracks or potholes or
any type of imperfection. The infrared equipment has been a big help in
overcoming problems quickly. You simply drop the heater on it, heat it up
for awhile, rejuvenate much of the old, damaged asphalt, and then you
resurface and seal it. The road surface is pretty much back to new when
Ortega adds that once sunlight has had time to bleach the new asphalt repair,
it matches the original surface so much that you would be hard-pressed to
locate the restoration.
The infrared equipment that Commerce City purchased is a trailer-mounted Kasi
Proheat 2 Ton Minuteman model, a self-contained asphalt restoration system.
It is ideal for permanently repairing all general asphalt defects including
potholes, surface cracking, utility cuts, trenches, birdbaths and manholes.
The leading manufacturer of infrared asphalt restoration and repair equipment,
Kasi offers a range of trailer- walk behind and truck-mounted systems and
related equipment including transportable compactors and other reclaiming
and asphalt tools.
In operation, the infrared asphalt systems are much more efficient than
traditional cut-and-remove asphalt repair. Kasi's infrared pavement-heating
panel with its Stainless Steel & Inconel Converters generates the Infrared
radiation used to heat the asphalt pavement, softening it without damaging the
asphalt 2 to 2-1/2 inches deep. Normal time is less than 7 minutes. The system's
reclaimer keeps asphalt at plant mix temperature in any kind of weather, and can
also reclaim stockpiled asphalt.
Using an infrared asphalt reclaiming and repair system, the savings on labor and
repair time as well as materials are very substantial. Infrared restorations fuse
to the existing pavement, creating a continuous surface. This eliminates the need
for tack-coating the edges because the seams have been elminated, enhances
durability, and allows roads to be opened to traffic immediately. It also makes
the repair process less expensive, since existing asphalt is recycled, crew size
is typically limited to two; and only a single truck or trailer is used.
These benefits have made the use of infrared systems highly popular with independent
contractors who service state and local governments.
Paul Gustafson, owner of Woodbury, CN-based asphalt repair company, CT Infrared,
has tripled its business volume with half the labor in two years using a Kasi
"Going from traditional cut-and-remove asphalt repair to infrared repair has tripled
our business and profit, while cutting our costs in half," says Gustafson. "Instead
of cutting, removing, and throwing away a traditional asphalt patch, we can use mostly
recycled material. We can do a typical 5x7' repair in less than 20 minutes completed
with one piece of equipment, a truck, and two guys. Since cars can drive on it
immediately, there's almost no traffic disruption."
Gustafson adds that previously his crew was throwing away five tons of asphalt a day
from cutting and repairing. "Now we're able to reuse that asphalt, which for us is
a savings of about $650 per day," he says.
To do the same 5x7' cut-and-remove asphalt repair would typically take about five or
six laborers several hours of work using a pavement saw to cut a straight edge around
the damaged area, a jack hammer to break up the existing pavement, a bucket loader to
excavate material, two trucks - one to remove excavated material and one to bring
fresh asphalt - and a roller to compact the repair. It would also require enough new
asphalt to replace all the excavated material.
Infrared asphalt repair withstands weathering and traffic to last much longer than
conventional repair as well. "When a utility company did a compaction test on my
infrared repair, it had a 95% compaction rate which is phenomenal," says Gustafson.
Unlike conventional "saw, cut, and remove" or "crack filler" asphalt repair techniques,
infrared asphalt repair has no seams for water and ice to penetrate. Instead, its infrared
restorations fuse to the existing pavement, creating a continuous surface. This eliminates
the need for tack-coating the edges, enhances durability, and allows roads to be opened to
