Hi Bill
Be careful with full depth repairs as IR is only good for about 40-50mm depth. Your average depth of a full cut (top/base) is between 90 & 120mm so cracking may re-appear!
Inform the customer and/or suggest alternatives; a lap joint, a heat remove-reheat compact-replace original heated material into area to finish to give a long term joint repair.
Obviously the more north you are the more freeze/thaw cycles will impact the area. I can’t speak for southern states-they may succeed with a single heat on full depth cuts.
Regards
