Hi, I mostly have done patios but am trying to figure out the best way to do a driveway with pavers. I need to rip out hte existing aspalt which has been down for 30+ years. I was originally going to lay 8" of RCA and wait a month and then lay the pavers. A friend of mine said it would be best to put down a 4" base of sand mized with cement and dry lay the pavers over that. The cement will add much more to the price which is not a concern but he said that the pavers won't move and it is a better job. Any advice is appreciated. Also what is the siggested ratio of sand to cement. Thanks in advance.
