I am replacing 50-years old asphalt driveway with pavers. Talked to several contractors in my area. Some are insisting on excavating down
8 to 10 inches and then backfilling with crashed stone or "QP" and compressing it with a roller. Some are saying that excavating down 4 inches and compressing it with a "jumping jack" is enough since driveway has been in place for so many years and that excavating and backfilling will only make it worst by disturbing existing very solid base. While I don't want to pay more money than I have to, I want to make sure that I am not going to end up with uneven settling pavers all over the driveway. Please help, any advice is appreciated.- posted
