Here is a step-by-step guide to the repair process for long-lasting results based on leading industry advice :
STEP ONE : Clean the repair area — The area to be treated is swept or blown clear from debris and thoroughly dried out to ensure that nothing blocks the infrared repair unit from reaching the asphalt surface .
STEP THREE : Position it over the damaged area — The infrared heater is placed above the damaged asphalt area and make sure to position the wind skirts to keep the machine stable .
STEP FIVE : Scarify and rake treated area — Rake to remove loose and failed aggregate . Scarify the surface .
STEP TWO : Unload the unit from the transport truck and prepare it for use — Make sure to inspect it for any damage or obstructions and then position the wheel casters for use .
STEP FOUR : Heat the damaged paved area for about 5-10 minutes — This heating time may vary depending on the existing aggregate , the season , and the depth of the damage . More extensive asphalt pavement damage takes longer to treat .
STEP SIX : Add rejuvenator — A rejuvenator should be added to the remaining aggregate , replenishing oils lost through age and oxidization .
