Recycled asphalt..When can I seal it. Sooner the better.

There are also cold mix methods that are used on gravel or dirt roads.

Think about the chip coat's put on new existing asphalt roads. A tack coat is sprayed on the existing road, then clean chipped gravel is spread over it and it's packed in with a roller.

It is all about the type and quality of the bitumen products and how they are applied. What's available in bulk to commercial business may be quite different to what an individual can access in 5 gal. Buckets. Many of the products require heat to be fluid.

This is what I would do as well. Have someone chip seal it for you. I have seen it done on long driveways here and it seems to wear very well. The asphalt millings is the base and the chip seal is the wearing top coat.

FWIW... learned the DIY seal coat I mentioned earlier is water based, not oil base which concerns me a bit with respect to binding with the substrate.

Dragoneggs the sealer is probably an oil/water emulsion. This is typical from all homeowner and lower end commercial products. You need specialized equipment for the polymer sealers

I will run a test sealer on it this week. If I cannot stop it tracking into my house I will take it out and put my stone back in. I put stone in a couple of years ago to stop the gravel coming into my house. Now I have the same issue again. Driveway is hard except like a dust on top. I can scratch it with my foot. I will only seal a small area to see if this will work as I can put my stone back in quickly. I can put this behind my warehouse to make a pad for my attachments and trailers. I am willing to spend a little bit on it but then get back to what I know. Maybe in time the top with harden up but I just am not seeing it happening. So far I hate it.

I have spread TONS of millings. Almost all of it for contractor parking areas or an access road to a contractor yard and I usually put it down at least 6" to a foot thick so it will bind. Since it is just used asphalt that has been ground up it doesn't have all of the binding ability of fresh asphalt. I never recommend using on a residential driveway because like you're seeing, it always has the loose stones that don't pack in on top, it is very hard to patch a low spot or a pothole after a couple of years and get it to hold, and if it's not put down thick enough it just won't bind.

Don't get me wrong, I completely see the attraction to using it, it can be had reasonably cheap and it kinda looks like a paved driveway. I'm pretty sure if you try to seal it you ( or your wife) won't be happy because you'll be tracking little stones with sealer on them in the house now. The best option may be to professionally chip seal it, they spray the sealer and roll in some stone on the top....

I would expect that you are probably right. I will take it out first though.

Most around here use it for long stretches of driveway but don't use it close to house,

For instance I use it for two long access roads out to the barn right to the door but the driveway to my home the millings stop at the beginning of my main parking area and garage entrance That area is concrete

I don't have any problems patching pot holes when they do occur but that is a rare occasion for me.
