How learning infrared patching done right
can bring profits
By Jeff Winke

nfrared patching is a method of blend-
ing new asphalt with existing to create
a joint-free integral patch. The
truck-mounted machine is capable of
heating the existing pavement material to
a depth of approximately two inches with-
out oxidation or burning. There is no
flame in direct contact with the existing
pavement surface. The truck unit is also
equipped with multiple heated chambers
capable of storing and transporting up to
four tons of asphalt materials, while main-
taining a consistent materials tempera-
ture.
There are numerous advantages of infra-
red patching:

• Time - Depending on air temperature,
the entire process will take from 10 to 20
minutes. The traditional method, involv-
ing sawing-cutting, excavating, and repav-
ing, typically requires much more time.
• Convenience - There is the ability to
complete the repairs during off-hours
even when asphalt plants are not operat-
ing.
• Quality - There are no new cold joints
created, which means finished quality is
better since there are no open seams be-
tween the old pavement and the infrared
patch.
• Cost - Infrared patching is a cost-effec-
tive alternative to traditional patching.

Infrared pavement repair method has
numerous uses. The method is used to re-
pair holes and surface deteriorated areas;
to eliminate depressions, water holes, and
tripping hazards; to achieve smooth black
top at transition joints; and for repairing
newer pavement without any sawing or
cutting. Infrared patching is also used
to adjust pavement height to manholes,
lower high areas, and repair deteriorated
paving seams.
Receiving proper training for infrared
patching methods is critical for the success
