I love seeing these machines work. Every time I pass one, I turn into a 3 year old and want to stop and watch.
Thanks for a great narrative and no obnoxious whacko music. Most educational. We use triaxel dump trucks as we can fill the whole box.
I learned how the worn out road asphalt is used. Great video!
Thanks for explaining the difference between milling and profiling
I am currently taking the course of Pavement Maintenance and Rehabilitation, we have practiced a lot with this content, thanks a lot appreciate it.
easily one of the worst examples of milling iv ever seen
Yeah I've operated a Wirtgen for a few years and this doesn't show you a darn thing
Excellent presentation. I was an inspector working with many building materials and structures. I learned more about my job over the years from the contractors who actually did the work then anyone else.
Very nice video! I’ve been interested in this process since I was very young, and now I’m finally learning how it actually works.
Very informative content here. I'm going to school for construction management and this is the industry that interests me the most. Thanks for the video.
I know high school drop outs on drugs that can run these machines u dont need school u need a job
@@robbyabrahams1299 He probably won’t be on the site very much.
Something to add from a safety standpoint... Never, ever stand behind the mill when the drum is down. Every once in a blue moon, the track leveling system drops the drum too fast and the machine will take off backwards FAST on the drum, usually throwing the operator off the machine. It then becomes a runaway machine. That's one of the reasons there are so many emergency stop switches on the machines.
These newer wirtgens are good for safe on traveling backward, they have multiple settings for drum speed plus load control. With the older mills iv been on a few for that backwards boogie, both roadtec. Never on a Wirtgen
THANKS MR. FLINTSTONE
Who the hell is “operating” the machine when that happens? Maybe a hydraulic issue if your mill drops. wtf. Lol
super video,génial le systéme des bennes pour vider.
Clean the spray tip on spray bar. Clean the tips on the lower conveyor the two clean the two tips on the upper conveyor, clean the two tips for the spray for the fan that should be on so there’s no dust. I ran a milling machine for 25 years.
I remember seeing, somewhere between 40 and 50 years ago, a roadworking machine that was an all-in-one road resurfacing machine. The road in front of the machine was all crappy and pitted, etc, and the road behind it was nice pristine steaming asphalt road surface. Never did find out why it didn't become widely used, or if it's even used at all.
not to many here in the states that i know of
I really like the sound of the engine when the operator switches on the part which activates the milling drum to process the milling of the asphalt. So quiet that I don't even sense the activation of the engine.
Very informative thanks guys
Interesting video. I liked the shot of the cutting head. Very similar to the cutter on underground continuous miner.
Appreciate you making this video. I’m working on airport taxiways and runways and needed to get an idea of what is actually going to be happening on this side of things. Glad I now have an idea of what I’ll be looking at!

Man, I would LOVE to do this out here in California. I already have my Class A. Had it for about 6 years. I want to reach out to my local Union for this.
good job.nice match.we mill in pa with older cmi.great machine.we have to mill out a section with 5 inches of concrete, 4 inches of ashfalt, and 2 inches of dirt and stone.total of 11 inches in one pass.did half last year and the rest this year.alot to take out
Worked on a job with the CMI, yep they can (all machines really) can make quite a deep cut, just go slower and need more trucks. Great video
Great commentary one of the reasons I subbed hope to see more from you.
Here in New England as there is a lot of milling and repaying why don’t they off set the lane they pave so the lane gaps aren’t on top,of each other ? Nice video and very informative. Thanks
thank you for making this video, I am a graduate civil Eng, this made a lot of sense.thank you again

Flagged here in tn. for Highways inc., Patty Construction, Weeks Paving, and Phaltless in Chatt. Need a GOOD set of flaggers to keep the traffic away. Lots of fun, can be very dirty especially if the miller runs out of water.
Thanks. I learned a lot.
Just retired from pavement recycling in the United States. We operate the machine and depth control with only the top operator. I count three men on the ground.
Very nice video!!!!
Pretty cool Ober. I bet Gunther could do that with just his Kubel, Lol!
One of these machines is operating right past my house as I watch this.
i use to roll with the mill….one company that i’d haul the milling for in FL was a jerk he wouldn’t taper it and you’d get that drop off or huge bump at the end ✌🏻
Truly beautiful
Very informative video, great job to you! My only concern is that too many of the workers weren't wearing any dust masks.
15:22 I don't think I've seen that often. Usually they just leave a bump. In reality, it's miniscule if you are used to driving on dirt and gravel roads, but some traffic treats it like a cliff and goes 1/2MPH.
Great Video, thank you for making it, I've learned a lot !!!
That's the only job I hated driving dumps for many years, most of us did--damn milling. You couldn't crawl slow enough for those damn machines back in the day. Even in granny, you'd have to push in the clutch, let it out slow and the guy would make the slow down sign again. That's the only time I ever needed a clutch adjustment in my life was when there was a milling job lasted a month!
Whole fleet needed clutch adjustments!!
For you kids out there who have only drove the automatics, we most of us never used our clutch except to put her in gear....and the DAMN MILLINGS!! LOL!! Hell, I miss hauling asphalt so much I wouldn't bitch about a milling job never again!! Would of been nice to have an automatic, MILLINGS Made Easy.
1 Caterpillar Skidsteer that is yellow with black and orange stripes and has a brush on the front of it and the number on the Skidsteer is 2720 .
I love seeing road construction and hope yall get a lot of money from the infrastructure bill.
Kinda have mixed emotions on that, America can't afford all this crazy spending.......I mean someone has to pay the bill later.
@@Ober447 Not enough of us have that mentality. Thank you for saying it.
I noticed the road base layer (in its milled/planed state) below the running surface also had cracks running through the pavement. The new matt may start to show similar signs of failure in the not to distant future. You may need to plane/mill deeper, as there appears to be a problem at a deeper level.
This particular job was a mill and seal project and its aim is to simply replace the wearing course and buy the road another 8 -10 years before a more comprehensive Mill, Base and Seal. When we want to slow down reflective cracking we will use a Full or Partial depth recycling mix then base and seal.
@@Ober447 Good man; you've bought yourself some time. Best wishes from Scotland.
This was so helpful for me man thanks for the video bro
My question is. What do they do with the old asphalt? Does it get colored darker, reconditioned and put back on the road?
Goes through a shaker put into separate piles at the asphalt plant then added into fresh asphalt as a filler according to the type and size of stone
Great video on an otherwise obscure subject.
👍😉. Awesome.
Help.......I have a concrete driveway, previous owner put asphalt over the concrete.......can the asphalt be stripped back down to the concrete?
Yes, by means of a milling machine or an excavator with a smooth edge ditching bucket. However you will never get the asphalt stains completely erased
@@Ober447 thanks for the ideas!
How many times can you recycle that asphalt?
Unlimited. They blend it percentage wise with fresh sand and stone preheated then add the oil.
How thick of asphalt pavement can you remove from a single pass?
Typically 50mm or 2" for most paving jobs.
That dust can’t be good for those people who are working
it’s more of a hot rubber smell
They’re not very smart at all.
That's the easy way, guy don't have to keep start and stop...but when you had a bunch of Tri-axles, it was tough on the driver.
No obvious concerns about the amount of dust generated. Once this dust hits the lungs, it’s there for good!
What's with the lack of traffic control? That's a major hazard for these workers unchecked.
The TCPs don't stay with the grinder, they stay at set stations in intervals of one kilometer. So the grinder works within a 1 Km work zone and stays in that zone until the area is completed. At that point there is a brief pause while Flaggers move to another station and milling resumes. This is also a very low traffic road with less than 1000 cars per day and speed limits are reduced 20 km/h in work zones. If things become unsafe we implement a "follow me" vehicle and convoy traffic through the site.
Not enough room to use cones to separate from traffic. The gate on the side of machine dictates the depth of cut and cones just get in the way sometimes
How much does it cost do that for a small dirt driveway?
These companies specialize in highway work and employ equipment too large for smaller projects like driveways. I would suggest contacting one of you local paving companies and asking for an estimate, most do free estimates. Hire the company with the best reputation because using the lowest bid always means poorer quality asphalt being used.
Is that asphalt going to be recycled or just left there?
We will screen it down to 1 1/4" (0-31.5mm) and haul it back out and use it for the shoulders. Anything else leftover will get trucked to the nearest maintenance depot. We do at times recycle milled asphalt back in new hot-mix but only at about 15-20% content. We have gotten away from recycled mixes in favor of warm mixes in recent years.
Ober447 That’s good. Thanks for the reply
@@Ober447
I need milling machine,
Usually the asphalt once it gets chewed up and spit into the dump truck goes to the asphalt plant to be recycled into the new mix
I've been doing this kind of work in particular for the last thirteen years I drive a quad axle dump truck and I love it, especially when it comes time to pull the hot mix from the plant and repave the road with it
Wow
What's the pay rate for the loafers standing around with their hands in their pockets? Where do I apply?
What would you have them do? all road jobs, local, state or federal REQUIRE a minimum number of employee as specified in the contract. It will depend on what the job entails. so the so-called "loafers" most likely have a critical part in the ENTIRE job, just not at the moment of video. 15 or more hour days are not unheard of and again what the contract specifies some jobs go 24/7.
What is the forecast for paving the entire highway?
Another 5 days for base, seal and shouldering to completion.
@@Ober447 , thank you. Communist congratulations!
@@academyofartscienceandphil2106 Communism sucks and only losers that cannot do anything for themselves promote it.
Here I am sitting in my cubicle wishing I was operating a big ass construction machine!
Anyone know what those two large diameter hose lines are on either side if the conveyor? The black ribbed hoses.
Vacuums perhaps.
What is there immediately below the milled asphalt layer? Its that a pavement of reinforced cement concrete or cement treated base or something else?
Its base asphalt with light colored aggregate making it look like conctete
In Australia we sideload semi trailers to make use of the room up front in the bin
Tighten them holders up
Pls what is the name of this mechine
Wirtgen WR200
How many teeth on the cutting head?
Eu não falo inglês tem como fazer uma tradução pra português
Been on lots of these jobs, by the way the tailings are ECO-inert, so no special handling as it rains. most plants reuse a % into the mix as it saves money, the oil aka asphalt didn't go anywhere its in the tailings.
I gave up on this because there was absolutely nothing happening initially...
Noice
Don’t put the asphalt through a screen, it removes the fines….put it through a small crusher, set to between 1/2 inch and and 1 inch.
You will get 100% re-usable material ….goes down better and compacts way better ….
All round nice video
I can smell this video

HEY IS WHAT HEY IS A
It's kind of funny how the narrator pronounces asphalt as "ash-phalt" rather then as "ass-phalt." Otherwise, a very interesting video. 😉
Try 14 hr days milling 3 miles to dead end were from New Albany Indiana😂💪🏽
hats of boys that job told me to go back to trade school never ever again il do paving
ya asphalt. there’s another one my resume could land
Just like that
Ober447 - very important question/request for you, I am finishing up a construction safety video, part of which ties in with silicosis - for those who breathe in way too much dust from the ground, breaking rocks, concrete, or this crushed concrete - the very common dust crystalline silica - though I've noticed people really have to breathe in a ton of the dust over a period of years - or extreme exposures like the breathing in the dust from the twin tower collapse to get an issue from only single exposures. But anyways - I was needing to find some footage of someone milling asphalt to illustrate the crystalline silica that is kicked up in that task also - would I have permission to incorporate just a small bit of the clip showing the miller kicking the dust up? I can include just parts where you aren't talking. Just let me know if that would be okay. I do intend to sell this/strategically give it away for free to those who need it. In exchange for this - I can give the final product to you at a highly discounted rate if you are looking for a modern construction safety video (mostly specific to concrete construction) including modern medical treatments. In any case just let me know if that would be okay.
Thanks you for your time
I would need to get permission from all the individual people that are shown in this video and unfortunately that's not possible as many have moved on to other jobs.
@@Ober447 Ah I see - a creative solution I have is what if I blurred out the people shown in the video - I'd likely be just showing 10 seconds of your entire clip
Zero traffic control?
Full depth recycling Works in a 2km work Zone. Traffic control or set up at each end of the 2km Zone with a follow me truck leading traffic through the site. If you watch closely you'll see it pass, I believe it's a red Chevy half ton
Change some teeth too pattern looks bad hopefully they have the grade up a few clicks so when they take that shoulder pass at full depth there is no ridge and they better run the petntiometer or slope cause that shoulder is definitely higher than 2 inches
Why do many mispronounce the word asphalt? It is pronounced ( as-fault) not (ash- fault) .

Where the hell is flag person .big lack of safety
Dun many any miles of this..easy peasy..night work was the challenge...
I trust qq
THE PROBLEM DOSENT
RECICLED THE RAP 100%
Asphalt. Not ASHphalt.
What the farthest that thing can dog down to
Typically 2" but it can mill up to 6"
I thought that the safety geek in the green hard hat was going to get run over at 7:00. He had very poor situational awareness.
Good observation......green hats are first year employees and typically only stay one season. Paving isn't for the faint of heart.
@@Ober447 . I wasn't aware those were rookies. I'm a mechanical engineer and on some jobs, it is the safety geek in the green hat.
