Crush and Run vs Recycled Asphalt?

[6sunset6]

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.

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.

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.
