I have a paved driveway that seems to need repair or replacing. There are some cracks throughout, but near the bottom there are spider cracks. I noticed the other day after some rain that it felt loose and gave a little when walking over this part. None of the pieces are loose to the point that they can be removed, but water was coming out of them when stepped on. The rest of the driveway seems structurally sound, with minimal cracking. Can this be patched?
