Not sure what it’s called but essentially it can take up an asphalt road in no time.
Saw one in action on the way to the office today. It just eats it up, spits it out into a dump truck. They had 10-15 dump trucks line up just waiting to haul the waste out.
I bet they have new asphalt down by Friday.
Technology truly is amazing (in some cases).
Just think how long they used to take.
And now (well in Florida anyways) it’s lickety split.

They take that aggregate, mix it with several other products and reapply it about as quickly as they chew it up. The asphalt paving business has a lot of sustainability in it these days.

Yes. We deal with the “asphalt grindings” every year. However only a certain amount can be recycled. Some can not due to contamination by stone and dirt. Some can not because of the original chemical makeup of the asphalt being ground up.
I have 319 loads coming in on Monday. It makes great fill and if it is properly compacted it makes perfect road base.

I thought about using old asphalt aggregate when I did the gravel driveway. But you need a guy to compress it with one of those roller machines.

How is the recycled concrete holding up that we put in? It is doing great. I am still thinking one more load maybe next year to take it to the edge of the road and top off the rest. |

Those milling machines cut through concrete also. That produces a fine product that is very good for driveways or parking lots.

Round these Country towns when they repave the roads all the driveways on that road get a millings driveway.
Guess it must be cheaper than hauling it off.I think it's about $ 450 a load delivered or free if your Right There..

They use milling along side the roads when repairing truck damage from parking. Thought it self compacted. Milling and resurfacing give the road 10 years of life. |

Every comment here is mostly correct. I paved roads for years. In the many counties of Florida the rules vary.
Typically the milling machine shaves off 1" or so, depending on the existing condition of the roadway, or highway, sometimes less, sometimes more. The millings can be used for many things, as noted, but typically go back to the asphalt plant to be used to make "new" asphalt. Then, after milling, new asphalt goes down.
Granite rock, the rock in asphalt, can be re-used until the end of time. The primary reason for roadway sags in travel lanes, are because the base, typically limerock, sags, or the subgrade, sags. After millions of daily trips from cars and big trucks.

We've used a few loads of the reject on one of our roads that is particularly prone to rutting. Been 5 years now......grass is growing through it and you have to look hard in places to tell it is there......but it's holding up.
Interesting thing......we can not use it for low water crossings, something the crushed concrete is excellent for. Can't use it because with the constant flow of water across it the asphalt content caused it to fall outside of Best Management Practices as it leaches hydrocarbons too fast. At least that's how I understand it.
DOT was out looking at SR 100 on our north end a couple of weeks ago, supposedly prepping to let a contract to resurface. You can bet a dime to a dollar that we'll be out there offering to take their "rejects"......!!!

Dade doesn't do anything with the dirt roads so we have to take care of them ourself. Every couple years I get a load from a friend that owns a paving company. Fill in the holes and run a bobcat over it to pack it in. Once a hole starts and it rains they develop pretty quick. All the delivery trucks don't help. They seem to aim for the holes.
