So I had a local contractor drop off a 5 gallon pail of their asphalt millings and get me a quote on spreading and compacting it over my driveway. The millings all came from driveways he has ripped up over the course of this summer.
Every post online seems to mention that you should look for asphalt millings that look "good" but nobody gets into detail on how to really identify good? should it compact in my hand a certain way? should I be able to pour a bit and roll it with my car to see somewhat what it might be like or is it really just NO comparison to once a roller has gone over it?
People say it sets up like a traditional drive after time and compaction but this looks nothing like I would expect a traditional asphalt driveway to look like?
The color seems a dark brown but there are a lot of fines in it.

I found a few pictures online. This is close to what I think was sampled:

which has a sandy loam earthy brown kind of look to it

But this is I guess what I expected or think of what the coloring and consistency (less fines) should look like?

either black, or varying shades of gray instead of much browns and tan.

Am I crazy and just expecting it to look more like finished product I see or should there really be a lot of fines?

Should I try pouring it in a patch and hitting it with a post hole digger flat end/rolling it with my car/ hitting it with a torch/ adding a touch of diesel/etc. to see how well it packs down or will that show me nothing?


Those of you with rap driveways, what did the actual product look like close up before it got delivered? how did the base you used compress and Did it set up for you hard enough over time to roll casters over, use a jack with, snowblow with low set skids? How does it compare to asphalt top mix for you? I have read hours and hours looking at tons of threads so I know it doesn't always set up exactly the same and I don't think a jackstand will sit on top nice and clean without a dent but I am more looking for the relationship between the end result and the materials used.

Milling/RAP straight from a milling project or stock pile will often have "chips" as big as maybe 2"x4" by depth of lift (1-1.5"); fines, dusts, even some limerock from over milling. The stuff from your first picture looks like it was crushed on a secondary crusher. That would be significantly more money. Both pictures look pretty good, but if these milling came off of driveways then you can expect more trash, dirt, base etc in the material. Driveways are typically much thinner then a road (driveway=0.75-1.5"; road=1.5"-4+"), and when you mill a drive you will get into the base material, and that ends up in the millings. It should still pack well, maybe post a picture of what you've got.

I agree with Paul Harvey comments on your material
A RAP driveway will be a step between gravel and asphalt drive.
The RAP will never bind together as much as the asphalt , it will be closer in performance to a gravel drive

Construction company who brought me the bucket does his own work and has his own material stockpiles. This is all 1 inch minus stuff and I think was secondary processed. I'm getting a regrade and about 40 tons put down with a roller for about $1200 or so if I go with them.

I'll get a picture of what I have too and was planning on putting that up already.

Biggest driver for me for this is getting something a little more solid than the crusher run I have down now. it packs hard but I have a lot of loose 1in stones that launch in the snowblower if I don't set the skids to 2 inches... which means wintertime ice skating rink for my driveway. I want something to pack as hard or harder than that and not have to worry about breaking car windows.

Unless you prime and sand the new RAP, you will still have some loose material. It does pack down well, but it will loosen up on the very top from turning your front tires ect. Prime and sand would probably add an additional $0.50-1.00/square yard if your guy has a tack wagon.

Also, you say you have crusher run now, if your adding less than 6" of RAP on top, you/he will need to scarify the existing rock before placing the RAP to prevent "scabbing".

We sell both crushed asphalt and asphalt millings. The crushed is cleaner and has no large chunks, runs $14/ton + delivery. The Asphalt millings have some dirt and some larger chunks but still work really well. They run $10/ton plus delivery. Both work well on driveways.

OK,
Here are some pictures of the actual material.
More in the album. Driveway Photos by tastyratz | Photobucket

in my hand, and this has some moisture content darkening it:


poured out on top of my garage concrete apron:


Here I poured some out onto my crusher run driveway and rolled over it a couple times with my car. Then I hit it with my blowtorch and did some hand tamping to see how much bitumen remained and how hard it got.


Looks like it got pretty black pretty quick?

What do you guys think?

IMG_0420.jpgIMG_0419.jpgIMO, asphalt "MILLINGS" should have no dirt. If this guy says he is getting it off driveway jobs I would be a skeptic- he is using a reclamer, not a milling machine. A milling machine is about a 700,000 piece of equipment that does just that- it grinds an inch or two off the surface-although they can do much more. end result is you get fines, certainly under an inch- occasionally machije will ripmup a bigger chunk. Good stuff will look moist-in particular when it is exposed to sunlight. I have a fair amount of experience with the stuff- did about 37 trailer dump loads at our fairgrounds. Also my own driveway about two years ago-has held up very well. Used a small Vib roller (rear rubber tire drive) which is key. Also you want toput it down on a hot day or for sure with good sun.

I'm no expert with this stuff, but it looks too sandy and dry.

To give you something to compare-
I just got a 20 ton load of regrind from MAJOR local asphalt company .
Total delivered price was $449.00 or $14.50 ton + delivery. It's very good quality.
I got a load 8 years ago that was NOT reground and it had chunks in it up to 2" X 6" X 6". I even found one of the carbide teeth!
