Crush and Run vs Recycled Asphalt?

[RockCreek]

I currently have a 900' driveway that will need to be finished once our house is complete. I recently saw an ad for recycled asphalt and want to know if anyone had any luck or experience with this. It is cheaper than crush and run. I've heard that once it is compacted, that it smoothes out like a paved road. Just wanted to hear your guys opinion. I rather do it right the first time and not waste my time and money. Thanks for looking.....

It does work well, but you still need the a solid C/R base that is packed well.

I have put asphalt millings on my driveway which is about 450' long and extremely steep. I started with regular gravel and found I was chasing it down the driveway everytime it rained. The cost of the millings is almost the same as gravel, but you want to make sure to get some fresh millings if there's a road project going on close by, you can usually get a good deal. Once this is packed in and on a solid base, it will set up just like asphalt, not quite as smooth, but a 1/4 the cost of asphalt. I even sealed my driveway and saved over $8000 to what it would cost to put regular blacktop on and it's 4-6" thick all the way through so I have no problem running fully loaded dump trucks on it and don't have to worry about it breaking up. The main thing is, make sure you have a solid, stable base!

Recycled alphalt drives are real popular in these parts of SC mainly because of the lower price. However, I am not a fan of it and I think it's overrated. Yes, it will flatten down but it will not ever lay out flat and smooth like macadam or black top roadways. The edges will continue to break off a bit at a time making it risky to mow along.

If you can't afford all concrete, then spend a little extra to do a blacktop driveway with first pass materials.

Recycled asphalt--great stuff, will not erode as crushed rock will do and over a short enough time it will actually re-bond to a 'macadam' like texture.
Mine was done about 15 years ago and has stood up really well.
Trick is to have a 3-4 inch layer of it and let traffic/time do its thing.

Perfection would be to run a vibrator roller to compact it.

My drive was to hilly, so the applicator drove back and forth with a loaded dump truck that had bald tires for compaction. Did the trick!

Do it again in a flash.

have the recycled asphalt put down, then have it rolled, then have some lean mix applied, sand it and you will have a decent top course to your stabilized subgrade.

Yep! Had some on my steep drive a few years ago after having seen it on another driveway. Worked quite well! The guy that did mine went over it with a vibratory roller, and I already had a good, solid base. It has held up well for 10+ years, with only minor touch-up. I'd recommend it. Next best thing to real paving, IMO.

If using recycled asphalt, order double grind or regrind. Straight off the milling machine, it gets kinda chunky. Have it tail gated at a spread rate of 4-6". Then add a hot coat of emulsifier, roll and enjoy. Just thoroughly wetting the material with water prior to rolling will give decent results too. The key is compaction and a smooth steel roller. They're cheap enough to rent and you'll be much happier with the end result.

I don't even recall what state I was driving through at the time, but I recently saw a machine that was not only grinding the roadway but literally recycling the material and re-laying it as it moved along. I thought it was not only pretty cool but figured it had to be saving time and resources. If more of those machines appear it may become more difficult to get their cast off grindings since there won't be any. I have no idea how well they work, suspect they'd work well, but you may want to get them while you can if you want them.

Would hate to see that happen.

Last spring the county had a contractor with a preheat truck . flatbed with big heaters pointed at the pavement under the flatbed. The second truck also had heaters and some kind of vibrating forks. Something like railroad ballast shakers. Follwing were regular rollers. I think the second truck also added some kind of binder. So they recyled the pacement in place. Then they paved a top layer over it.

Thanks to all for the great info. One other thing that I forgot to ask from the experienced individuals, was there any bleeding from the recycled asphalt? My concerns are kids and pets tracking in tar. Thank again to all.

if you put mat under it and keep it 4-6" thick you will be glad you put it down, even though it will cost more as us will put more tons down. As a must you should use a roller to compact it when you put it down.

if yuo add lean mix or bituminous asphalt emulsion to it as a binding material.. yes.. you might get a few sticky spots.. just sand them and it should tighten up in a few days.

No bleeding as the 'recycled' is actually kinda dry or evaporated as compared to fresh hot asphalt.

The more compaction. the better!

Geo textile underlay would be great if laying on a not so ideal base as it will prevent migration of undesirables to the surface.

Note that old carpeting (like remouved from, maybe a hotel lobby) would make a good substitute fo geotextile as all modern carpeting is made from synthetic materials.
I have seen many guys use this approach on mucky road beds as a method of stabilization.

Back in 1988 when I bought the property where I now live there was no road going back the roughly 1/4 mile to the place we were going to build our house. About 1/8 of a mile of that was across the edge of what had been a plowed field for the last, oh, hundred years or so. Needless to say, I had a soft base and it just happened to have rained constantly for about a month just before I needed to put in a road.

I went around to several carpet shops and asked for the old carpet they removed from houses. They were more than happy to oblige me. Heck, they even delivered! LOL Everyone laughed and laughed at my multi-colored strip of a driveway that had everything from long orange shag to what looked to be astro-turf. I should have taken pictures. The first trucks showing up with #2 rocks laughed and laughed and warned that I'd have to pay the towing charges if they got stuck. I had each tri-axle back spread their load as they arrived. None got stuck and it worked perfectly.

I couldn't afford the fabric made for doing what I needed, so I improvised and got by with no expense. Over the years I'm sure the carpet rotted away. Still, it worked as long as I needed it. We went for 20 years using the driveway with just adding a topping each year or so until I concreted the entire drive a couple of years ago. The idea of using carpet sounds crazy, but I assure you that it worked...and was free!

I agree. Our driveway by the house is a mud pit, but putting down crushed asphalt did the trick.

I've never heard of "crush and run"...I have used 'crusher run' many many times...it will pack down to a concrete like bed...it will also hold up on hills that other grades of gravel will migrate on...

also "crusher run" and portland cement is all that is required to make high quality concrete...as it is composed of both fine and course aggregate...

Not exactly

It may "work" in some areas.

My guess is regional slang.

down here it's lime rock.. in some areas it's lime stone.

lots of different names for aggregates too.. hard rock, 57 stone.. etc. etc..


stone dust, and 'fines' I've heard some people say, whereas down here we also just say 'crushed rock'... etc.
