“ An infrared patch ,” Blake said , “ if performed correctly , produces superior results because it creates a seamless , thermally bonded edge around the repair area . This thermally bonded edge will reduce the chances of water penetration into the repair area which is usually the main reason a repair area would fail later down the road . Most traditional methods rely on a cold to hot bond around the edges of the repair , so the adhesion between the new asphalt in the repair area and the surrounding pavement is inferior to that of the thermally bonded edge you get with infrared repair .”

Infrared repairs can help give a paved surface longer life … but how long ? “ This will vary but a general rule of thumb is 5-7 years ,” Blake said . “ If there is any type of base failure then this timeframe would be lower . The timeframe is also dependent on the age and condition of the surrounding asphalt as well . If the parking lot is in rough shape to start and the customer asks you to just perform a few emergency patches until they are able to afford a full depth reconstruction , then an infrared repair would buy them more than enough time for that scenario .”
Infrared repair is certainly not a fix all for everything . Contractors need to use their general knowledge and expertise to determine if an infrared repair is applicable to a certain job . Contractors should be up front with a customer and provide a realistic life span for a repair .
