EXPERT ADVICE Good Training How learning infrared patching done right can bring profits By Jeff Winke I 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: www.callape.com • 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. [24] 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 of this asphalt pavement repair methodol- ogy. “When done right, infrared training 1.800.210.5923
