Had originally thought of using calichi rock but after more research recycled asphalt looks to be best, least from a reading point of view, anyone used this stuff in real world conditions? Driveway will be 10'x100' then a 30'x30' parking area. I will spread it using my tractor and compact it best i can back dragging the FEL. Anyone know anything about this material?
They are a good product, but their not magic. They will never be 'pavement' and 4 or 6" of RAP/millings won't bridge swampy ground. They do hold up to erosion better than limerock, and they do form a more cohesive mass than 'gravel' or #57 stone. Expect to pay between $5-20/ton. Straight off the road runs between $200-400 per 20 ton load, delivered within reasonable distance, from an active milling job. Crushed, expect $20/ton plus trucking from the asphalt plant.
There are basically two types; straight of the road and/or the milling pile at the plant; and crushed. The crushed millings will have no large flacks, and is basically dust up to maybe 3/4". They pack very well, but they are much more expensive. Regular, uncrushed, millings work fine. You'll always have some loose pieces on the top, you'll get some RPMs and large flacks. They aren't a problem, but you need to expect them.
Edit: if you have a pretty firm subgrade, and we are talking about car and pick up traffic, I'd feel OK with 4" of RAP/millings. If you have heavier traffic, I'd bump that too 6". With an base material, it should be placed on compacted subgrade, free from plastic or organic materials. Once you place it, grade and compact.
Honestly, for my personal parking area, I had a well compacted, well draining area, dumped 4" of millings, spread with a box blade, and just let car traffic compact it. It looks and holds up fine.
Where people go wrong with millings is expecting them to either put 2" down on grass and 'boom' smooth asphalt. That's not reality,
