• If the driveway has areas where the pavement is rutted or severely broken, where the pavement sort of looks like the hide of an alligator – we call this “alligatoring” or alligator cracks– this is when you need to start thinking about new asphalt. When a pavement gets to that point you really can’t crack fill it any more.
  • To crack fill over a patch of alligator cracks would basically turn the area into a continuous sheet of crack filling rubber. If you would do that, in warmer weather, vehicle tires can adhere to this large area of crack filler and literally pull the pavement out of the driveway.
  • Also, a driveway that has been sealed/oversealed over the years can cause this alligatoring effect. The key is to look very closely at the pavement. Alligatoring from oversealing has more of a look of cracked glazing on pottery and doesn’t actually crack the pavement underneath, while alligatoring of the pavement will show actual cracks down into the pavement where an object like a butter knife could be inserted. Merely sealing really can’t cure either condition.
