Asphalt milling for Driveway

bondo · Aug 16, 2007

WOW, I just used my old BMC tractor with box on back to spread it out. Took bucket by bucket load with front end loader and did some basic leveling with then, then finished it off with the box. And as I said, then just drove over it many many many times. We tried to do this mid summer when temps were in the 90's and high humidity. So far it's seen two winters with plowing and still holding up really good. Even around the barns with the horses with shoes on don't dig it up when we move them between fields. I wish we did have a roller, as I think it would work better, not to mention faster!

Pardon my ignorance - how much volume of millings do you get with a ton? Or maybe I should ask how much compressed volume of millings do you get with a ton?

I would guess 120 lbs/ft^3, in place and well-compacted, which would be about 17 cubic feet per ton. Your vendor should be able to give you a better estimate.

Thank you. So two three-inch lifts would cover 34 square feet? And 100' of 10' wide driveway would be about 30 tons? Seems pretty cheap.. Unless my math is wrong, I'd pay additional for the good compaction.

Last May 2006, I put down millings on about 10,000 sqft on my drive/parking lot at 4-6" thick. Or approx. 100 yds., stock piled last 20 for future projects.

I was fortunate to check around with paving companies in the Rochester area and found Rushton Paving in Victor was doing a big parking lot in Rochester only 3 mi. from my house. The Manager was delighted to find a spot that close to the project to haul the millings, instead of back to their yard ,35 miles one way.

I got 120 yds delivered to my place ( 6 x 20 yd loads,tri axle dumps) , dumped in strategic spots for spreading. Took 1 1/2 days to spread and pack with the CK20.

Only bad thing was there are a lot of chunks 3 to 6" , I'm still raking out , from spots in the parking lot where the old pavement was only an inch thick and just pulled up instead of getting milled into 1" or less. Still has packed down very well. I plan to york rake and relevel a couple more times then rent a vib roller to final pack. Around here (NY ) some have used diesel or old oil as a binder, however these days you don't want to get caught by the DEC doing that, it will be a very expensive driveway!!! The alternative I will use is portland cement put down with a spreader, lightly raked then watered down lightly. Gives a very nice final surface, although some use crusher run with dust for top layer and work cement into that.

OH , I forgot to mention the cost for this project , $10-12 for diesel fuel , and $zero for millings, just got to be in right place at right time i guess.

Joe, you don't want to put diesel fuel or old oil on the asphalt anyway as it doesn't do any good things. It just dissolves/dilutes the bitumen based binder and you end up with dry aggregate.

You may be able to rent a small self propelled vibratory sheepfoot roller that would pack and break down the larger pieces of asphalt.

While I agree with what you're saying here, I 've seen some guys spray millings with diesel then light to melt the tar before rolling. At least that's their theory.

Just to clarify, I didn't say I was doing that and don't recommend it , see my quote : "Around here (NY ) some have used diesel or old oil as a binder, however these days you don't want to get caught by the DEC doing that, it will be a very expensive driveway!!! "

A few years ago, i worked for a road construction contractor in the workshop, during the winter overhauls.
The machinists have a sprayer (a handheld sprayer like farmers use for chemicals) full of Diesel to clean the pavers after the job is done.
The rollers were sprayed with water to prevent asphalt sticking to it. They were soaked and kept continuously wet.

The rollers are static Hamm tricycles, dry weight about 8 ton but when the wheels are loaded with water, they can get as heavy as 10.3 ton.
They had one roller with steel drum at front and two loader tires at the back, for compacting crushed rock roads. Also 1 rubber tire roller, which wasnt used a lot. They did most of the jobs with a universal machine, a vibratory Hamm articulating tandem roller with 2 wide drums, of which they had 5 or 6.
They told me that the rubber rollers could compact the asphalt more equally, because the rubber also pressed the lower spots, e.g they distribute the force over the full width, not just the high spots where just some pebbles carry the load..
Anyway, the vibratory rollers could vibrate the stones to spread the gravel in the mix, which is about the same effect as the rubber tire roller.

they said this rubber tire roller would be replaced by another vibratory roller when it was time to trade it for a new one, because a vibratory roller can do what a rubber tire roller can, but the vibratory was a lot more convenient.
