They are due to resurface the State Route by my house this summer. I hope to be able to get with the company doing the grinding and get a good price on five or six loads of that stuff and save them the cost of running it another 20 miles to the big reclamation pile. Great driveway topper.
Just make sure you get millings and not scalps
To add to confusion, both millings and scalps are often called "profiles"
Millings are the from the top inch of the road. This is mostly asphalt and will be ground like gravel. This is when the road is ground and not ripped up causing lines in the pavement. This type will be sticky with no more than 30% rock and big chunks of sticky asphalt. It can also be about the size of sand grains but made from asphelt and no rock.
Profiles are when you rip up the whole road. This usually come in big chunks that you need break up. It also contains the road base and is mostly rock.
When I put down millings I also sieve the pile. I have a sieve I use for the fire pile to separate ash from charcoal. Its just a frame set at 45deg with some weld mesh over it. On that is some chicken wire to make the holes smaller. I run a few buckets over this. This separates the really fine sand grain sized millings. I keep this separate in piles till then end of the job.
Once the rest is down I sooth out with the smudge bar and box blade. Then The fine stuff goes over the top which gives a really sticky smooth finish. Next comes wetting it down and rolling (lots of water and vibration). Last pick a hot day and dust with diesel. If it looks wet it is too much. This allows you to roller again and push down the rocks leaving the fine stuff sooth on top.
When your done it looks like any other road.
PS I put down a min of 200mm and roller down to about 150mm.
