Recycled Asphalt/ New pad for parking

Remdog, I used recycled asphalt on my parking are. If you are talking about the old asphalt they grind up out of the road we call them millings here in Florida. A lot of roads that used to be dirt roads are now covered in millings in our county. They hold up fine if prepped right. My whole driveway was done in them in 2004. I just had to freshen them up a few months ago. Your rv pad will be used rarely compared to the driveway. Just make sure your base is hard, Then spend the money to rent a drum vibratory compactor. Or hire someone that has one,to compact the millings.
