Stage One: No Damage, Clean & Seal
The very best way to protect an asphalt parking lot from oil damage is to sealcoat the entire area within 12 months of paving.
Stage Two: Minimal Damage Showing Exposed Surface, Repair Needed
When the oil spot on the pavement has started to create minimal surface damage to the top layer of the asphalt surface, the pavement now is in stage two of deterioration.
Stage Three: Severe Damage, Saw Cut Damage & Replace Asphalt
At this point, there is extensive damage and deterioration to the pavement. The oil stained area is now exhibiting softening of the pavement section. Your customer really only has two options to consider.
