Interesting. Some years ago around 1990 or so, they closed down one of the roads I used to use to get to and from work each day. For me there were plenty of bypass routes. One evening I was coming home around 8pm and as I was coming up to the 4-way intersection where I'd normally turn right on to that road (but would go straight during the closure for rehabilitation), I could see the machine that was doing the resurfacing. I stopped and parked on the shoulder back from the 4-way stop, and got out to walk closer. It was all one big long machine, and it towed a highway tanker along with it that supplied fresh liquid asphalt. It had a scarifier on the front that milled up the old layer(s) of pavement. It had numerous heating components, probably a materials grading plant because it was ejecting dust and very small rubble towards the ditch. I couldn't do a complete walk-around, and I didn't have a camera with me, but it looked like there was a slide-out hopper where a loader or a dump truck could add supplementary pea gravel to make up for whatever was lost in the process. But, broken down to basics, one long giant machine assembled together, it lifted up the existing old asphalt, sorted it, heated it, brushed the milled surface, mixed the old and some new material with new asphalt, oiled or coated the surface with a binding agent (maybe more liquid asphalt?) and then laid it back down and smoothed it with a roller. Other compressing rollers and a pinch roller followed behind to compact and finish-roll the new surface. It sure was nice to drive on when they were done. It's hard to know if that machine and that method truly got the job of resurfacing the road done any faster or cheaper than the traditional way using numerous machines and involving the removal and cartage away and then replacement of materials with new pavement, but it certainly looked more efficient merely "lifting and replacing" mostly the same stuff. It would have been interesting to see the operating costs per mile of using that giant thing, against the costs of a traditional setup where each individual machine must be used. I'd be willing to bet the hourly rate for that giant machine would scare the hell out of you, to see it on paper, but based on what I saw that evening and thinking about it, I bet the company doing the work was saving money over the traditional methods. As I recall, the rehabilitated road turned out as good as any other rehab'd road. I travelled that road for another 3 years before I was transferred within the company to work out of head office in another town, and as I remember, that road was alright for that time.
Needed: Narration to explain what is going on. Maybe people who work in the paving industry understand what is happening, but to the average person, it looks like asphalt is being dumped into a very long machine, and then being laid. I don't see any recycling being done, and I've seen much smaller machines do the same thing. If the machines had been digging up the old pavement, processed in place, then laid down as new asphalt, THAT would be impressive recycling.
Bruce A. Johnson the first two machines are only burners...they heat the old asphalt up. The third machine is heating and scraping the heated asphalt usually into a windrow but tjis one seems to have the ability to feed it right into a paver combo mixer...they add new road tar and a 10%mix of new asphalt to the old asphalt then feed it into the last machine which lays out the newly mixed asphalt. I have been on the dump truck feeding the mixer on a similar set up here in canada.
I have seen what you are talking about Rob, but The process I saw used a cold milling machine to process old pavement, feed into hopper/mixer, processed with percentage of hot new mix, screeded down (laid hot), then rolled. Crew was able to do many miles per day.
Please view this link, this process no need new HMA, th-cam.com/video/23VhOaavKuk/w-d-xo.html First two machines only heat the aged asphalt; third machine, scarifier the layer two inches, and fourth machine, asphalt recycling and extend final layer, 100% asphalt recycling, 0% new hot asphalt mix
Interesting. They tried that here a few years ago and found it wasn't efficient and frankly gave a poor result so they went back to the "old" way of milling the surface, taking the milled product off to a recycling plant where it was properly recycled under controlled conditions and then used again. Meanwhile the milled surface was fixed as necessary and eventually resurfaced with fresh material from that recycling plant. That worked.
fernarias The last machine laying out the fresh asphalt is actually lifting and reusing some of the still existing road surface. For the most part though it was milled and hauled off first.
We did some of this around 1992 in West tn. Did well and the road held up great. But man it was murder in the tri-axle dump truck. We hauled asphalt that was mixed into the recycling. The truck ran, had a great AC. But could not overcome the 350 degree mix in the bed. Plus the heated road and grindings under the truck. Company that had the machines was out of Canada back then. They had normal propane trucks, with the burners pulled behind them. Then the road was milled up laid in the center of the lane.
Pete k If it’s the company I am thinking of they greatly improved their equipment towards the late 90’s when I refueled the propane tanks on the machines in Ontario. I could haul 24,000 litres of propane and the equipment usually took most of it. This equipment looks to be much safer and easier to refuel.
Please see my General replay above. Hopefully, you'll get a better understanding of this process. Agencies continue to use Heater Repaving BECAUSE it's cost-effective and performing as expected.
They do this in Florida since the 1980s. Florida sun requires frequent repaving. It works well. 1 machine removes top 3", of asphalt, screens the millings, reheats and adds new asphalt and binders then lays it back down very hot, rollers compact itsnd it's driven on 12 hours later.
Trying to save money by using an immediate recycle/repave just costs you more in the long run when it has to be repaired. Mill it and repave it with proper mix the way it should be done. Unfortunately, the people who sit at desks and make the financial decisions, don't understand that going with the lowest bid often has consequences.
Let me argue with you. I’m not sure even short therm i think this is an expensive process. Look again they are using 3 huge machines. They cost allot more then conventional machines. Also the amount of gas they burn... is also a very slow process. I want to say this process is not a huge cost saving compared to traditional one. And i’m on same page with you. They should have gone straight for the normal process.
Fellas this is how things work, your government keeps printing all those fake dollars and a clever person invents a way of relieving them of the currency!
Please see my General replay above. I totally disagree with your observation. Quicker process, less materials, fewer lane closures, lower user costs for the same equivalent product makes total sense. Mill and Overlay usually is very wasteful and expensive. Our process gets credit for the same service life as conventional Mill & Overlay. Agencies continue to use this technique for one reason - rehabilitate many many many more miles of road for the same budget. Same performance for less money. It's a no-brainer, in the correct application. We are always a SubContractor. Give the same exact quote to every Prime. They fight it out on Trucking and HMA. Low bidder has no meaning to us.
They use that kind of machines also here in Finland, they mill only worst places and potholes. That's pretty fast and cheaper than other methods. But i think pavement isn't so strong than it should be. After one year there is holes, rails and bumps on the roads and here isn't so much traffic so it should last longer.
Many roads in Western New York need a lot of help because of a serious problem with potholes and rough areas. Our winter weather really wrecks our roads. Patching just doesn't work.
New York (with the exception of the Cross-Bronx Expressway in NYC) has infinitely better roads, and infinitely better road rehabilitation than your neighbors in Pennsylvania, where all they ever seem to do is put new icing on the cake and never seem to worry about fixing the base beneath.
These machines look so much easier and safer for the propane driver to refuel. I used to refuel a company in Toronto that I only knew as H.I.P. (can’t remember the parent company name) and I had to put the hose up then climb up on it and get the hose to connect to the filler all while standing above the burner. One machine even had two 2000 gallon tanks that could hold 1600 gallons (80%) each. These machines have a nice level platform that is relatively low to the ground with the filler at one end away from the burner. I’ve been out of the propane industry for years now so I don’t know if they still work in Toronto in the summer or not
Totally different to how they repave the road in NZ. In NZ the asphalt is milled off, taken to the asphalt plant & then the road is prepared for the new surface. Then the new surface of asphalt is paved on & rolled.
At the pace this paver is going....the cost per mile must be astronomical! Whats the Propane cost? Enough to heat every house in Minnesota for a year I bet!
I use to work for a company out of Tyler, TX called T.R> Remixer Inc. we done the same work. I was a Pre Heater operator. Hottest job I ever had in my life. Paid well and I got to travel. Only thing was if we had a major break down we had to wait on parts if we didn't have any. Those machines are German made..
With new technology on additives and emulsifiers this is a good process for the top layer, both on cost and quality, it can even be achieved with 80% RAP (20% new mix to compensate for loss of the existing layer), overall costs much lower due to cutting out the quarry and refinery (lower virgin aggregate and bitumen quantity used), crushing operations (environmental), transport operation (less heavy traffic), and the asphalt plant operation. BUT, at the same time, around 100 ppl will lose they jobs...
The recycling machines I seen before they remove about 2" on the road and mix it with oil and then spread it back on the ground. I never seen a truck dump new asphalt in a hopper.
Why heating up the lower layer? I'm familiar with roadworks, but in Hungary we don't do this, a truck dumps asphalt straight into a tracked paver, rollers compact it, and that's it.
half the process machinery is missing... I've witnessed the full trainset go by... the pavement tear out, conveyance equipment, and reconstitution sections are missing... but sorta are redundant for long uncongested roadways. Summerland, B.C. section of CANADAS LONGEST North/South HIGHWAY 97 was 4 Lanes with LeftLane Turns Furniture in-situ.
Much different paving techniques and paving equipment used in NZ than in the United States. They seem to know what they're doing though and quite possibly this paving procedure ends up with a longer wearing road surface. Never saw propane used for fuel to power the paving equipment before either.
The propane does not fuel the paving equipment, diesel does. The propane is used strictly for the heating of the road surface and in no way runs the paver or preheating equipment.
Also, no sealing or emulsion done before asphalt laying leaving it without a waterproof membrane on the road. In my opinion, a very costly temporary fix that will cost more to replace later on.
Interesting to watch but what about reflective cracking if they are only remixing the surface material.. maybe it's only good for warm climates. I know in Canada with the freeze thaw cycles this wouldn't last. We require full depth reclamation or complete re construction. Nonetheless always interesting to see infrared technology at work..
Midstate Reclamation run at 6 to 7 inches deep alll over MN WI ND and further west...if you had issue with this process you go after the people who issued the contract. These people are doing what that contract says to do...what the fuck people dont know how public roads are managed?
@@munzy5865 well depends on where you are like im in canada quebec and patching will last less then 4 month event the best patch .... they usually get rip off with a snowplow or just give up from the weather changes ! the best way ive seen is grind the fucker up and re pave over it
I've been in the paving industry for 20 plus years. The asphalt you can buy these days with all the recycled materials in it is no where the quality of the all virgin material you used to be able to buy. Alot has to do wi5h how the asphalt is made and how the recycle is added but heat cycles on the materials including the oil play a factor. The recycled in place in our area just doesn't hold up. And other "cost saving" ideas haven't saved as much cost as they thought. They tried microsurfacing some roads but the first go through patch the road, crack fill the road, do 2 layers of oil and chip then microsurface. The road has reflective cracks in it within a couple months and a year later looks like it did before they touched it.
Please see my General replay above. I partially agree. Way more RAP in new mixes than ever before. Hopefully, you get a better understanding of the Heater Repaving process...and its benefits.
AMIGO DO VÍDEO TH-cam BOA TARDE. A RECICLAGEM NO LOCAL MESMO PONDO FOGO NO ASFALTO NÃO FICA BOM. NÃO EXPLICADO AQUI MAS ENTENDIDO POR ÀQUELES VERSADOS NESTA TÉCNICA !!!🇧🇷🇧🇷🇧🇷 OBRIGADO ABRAÇO CLAUDIO NASSER EX ENGENHEIRO DO DNER NA DECADA DE 1970.
Looks like an enormously excessive amount of energy to relay two inches of pavement. This looks costly, slow, inefficient and still needs large amounts of virgin material.
Please see my General replay above. Hopefully, you get the whole picture of Heater Repaving. It's actually more cost-effective, same pace, and ultra-efficient than typical paving operations. Obviously uses far less virgin materials. That's the point.
This is a money shit process. I've seen a similar process back in the late 80's in my hometown. It started off with one truck with fresh asphalt to load the machine. The repaver would remove the old asphalt and auger it into the dump truck. When full the dump truck would get in front of the paver where the old material would be loaded into the paver, reheated and applied to the street. A simple and efficient operation. One dump truck, one paver, one roller and a propane truck to keep everything fueled.
Please see my General replay above. Where are you located? Interested in seeing if it was a Cutler Repaving job. It does work, or Agencies wouldn't still be using it year after year since 1965. I do agree that wearing course specification can be improved to give better appearance/performance. I'm always pushing for higher AC Content. Beauty of Heater Repaving is that recycling takes place and the overlay lift is kept separate. Compacted together. "Looks terrible" has more to do with the specified new asphalt from the hotplant.
Clearly the top couple inches have already been milled and millings removed. First 2 machines shown in this video are not the beginning of the entire process & only heat up base layer, next machine scrapes old asphalt surface and mixes in the new asphalt or old millings that are brought in by dump truck, the final machine is the actual paver. Thing is, it's proven that 100% recycled asphalt surface won't hold up as good as new asphalt. Might save money in the short term though.
Please see my General replay above. Close, but you are referencing a Heater Remixing process. This is different. 100% recycled wearing course is definitely a bad idea. Our finished surface is new. Bottom half of the section is recycled in-place. Machines apply the two layers separately. Compacted as one.
Wow must cost a fortune to do a road like tis...profiling and filling with new asphalt is the only way to go. Looks like they've broken thru to the road base and I bet it became patchy and soft in areas. The problem with so much heat that it penetrates below the asphalt and if the recycled asphalt doesn't get to the right temp and breaking thru to the roadbase which in turns will break thru the recycled asphalt eventually as it's now soft. The depth of the new asphalt looks rather thin by the look of the cut to the existing asphalt. just my own opinion
Actually they add a 10% mix of new asphalt as well as refreshing the tar content with a percentage of new tar blend it and re lay it on the road and compact it. The extra burner is probably a waste of time and fuel...the new lift of recycled asphalt is actually higher and thicker than the old road next to it after being compacting.
@@robreesor5011 out here they usually come with what's called chip seal back east, out here they call it fog coat. And on higher traffic routes iv seen a layer of finish grade asphalt on top
Please see my General replay above. Video shows the takeoff to start the day. We were actually widening the roadway right there. Overlaying base course. The rest of the project was different.
Please see my General replay above. Far more cost-effective and efficient than Mill & Overlay. Video doesn't capture the whole project. Same pace as conventional paving oeprations.
Ridiculously overcomplicated and inefficient. Just mill off the old surface and replace with new. The old material can be reprocessed in a dedicated facility under controlled conditions.
Sometimes the really bad roads are in fact milled and then paved using this method, However, most are just paved over as is because paver used here is a recycle machine meaning a few inches of the top road surface is scarified and then recycled/mixed with the new asphalt to the main screed.
Almost all asphalt mix used today is of a very high recycled content. Properly processed recycled mix is indistinguishable from mix made with virgin materials. But yeah, it should be handled by the proper facility.
Please see my General replay above. Hopefully you get a better understanding of Heater Repaving. Far more efficient and cost-effective than Mill & Overlay. No need to mill and haul them off and then sell back to the customer in the new mix from the hotplant. Recycling that RAP in-place, is no different than the trouble/expense of an off-site processing facility. Old-school thinking has gotten our roads into this mess.
This process seems redundant, and a slow process and way too much equipment and labor. What's the purpose of milling the surface if they're recycling the surface on-site. Here we mill the surface and haul the tailings to the hot plant where they use a percentage of the tailings into the hot mix and the same trucks haul the new mix to a single paver where it's placed then that truck gets reloaded with millings, loaded both ways.
Noticed when the camera got to the end of the line that the last rig was sitting on prepared road bed. A proper road bed would have to be excavated at least a foot deep and layered with several grades of gravel, each layer rolled and compressed before the next. Then covered with an approx. 4" lift of asphalt. That lane will break-up in a very short time with more tax payer dollars spent fixing the first cock-up.
Please see my General replay above. Hopefully get a better understanding of Heater Repaving. You are referring to a complete reconstruction. Hardly any Agency is equipped for that anymore. Old-school thinking got our roads into this mess. Time to get them out.
be more efficient if you didn't have 15 people standing around watching or are they there for training purposes. some of those there looked like they could use some exercise.
It does look that way and it is slow compared to the speed of laying fresh on a prepped surface. However when you count the time normally spent ripping up the old and trucking all new product in, the slower pace of this process is still fast compared to all the typical steps put together.
Please see my General replay above. Hopefully get a better understanding of Heater Repaving and its benefits. Old-school thinking got our roads in this situation. Time to get them out of it.

Super dumps.... 24 tons....
Much different paving techniques and paving equipment used in NZ than in the United States. They seem to know what they're doing though and quite possibly this paving procedure ends up with a longer wearing road surface. Never saw propane used for fuel to power the paving equipment before either.
The propane does not fuel the paving equipment, diesel does. The propane is used strictly for the heating of the road surface and in no way runs the paver or preheating equipment.
@@somewhere-n-Texas Thanks for the clarification :-)
@@somewhere-n-Texas the propane would need to mix the asphalt and bitumen to get it to temp before it goes to the paver
Also, no sealing or emulsion done before asphalt laying leaving it without a waterproof membrane on the road. In my opinion, a very costly temporary fix that will cost more to replace later on.
@@munzy5865 Agreed :-) LR
In southern California this was called heater remix never worked
Interesting to watch but what about reflective cracking if they are only remixing the surface material.. maybe it's only good for warm climates. I know in Canada with the freeze thaw cycles this wouldn't last. We require full depth reclamation or complete re construction. Nonetheless always interesting to see infrared technology at work..
some of the first people doing it were from Toronto
@@internazi poor example....they are so far south, they don't experience true winter like most of Canada
Midstate Reclamation run at 6 to 7 inches deep alll over MN WI ND and further west...if you had issue with this process you go after the people who issued the contract. These people are doing what that contract says to do...what the fuck people dont know how public roads are managed?
Please see my General replay above. See better understanding of our process. Thanks for the comments.
For a not so heavily used road this methods can be really efficient, for main road it is still old way but hot on hot paving methods works better.
Please see my General replay above.
You have NEVER experienced heat until you've worked on a Cutler Repaving crew lol
Why would you need to when profiling and refilling the hole is a lot easier than this prehistoric method.
@@munzy5865 well depends on where you are like im in canada quebec and patching will last less then 4 month event the best patch .... they usually get rip off with a snowplow or just give up from the weather changes ! the best way ive seen is grind the fucker up and re pave over it
Please see my General replay above. I like your style! Did you ever happen to be employed by Cutler?!?
I've been in the paving industry for 20 plus years. The asphalt you can buy these days with all the recycled materials in it is no where the quality of the all virgin material you used to be able to buy. Alot has to do wi5h how the asphalt is made and how the recycle is added but heat cycles on the materials including the oil play a factor. The recycled in place in our area just doesn't hold up. And other "cost saving" ideas haven't saved as much cost as they thought. They tried microsurfacing some roads but the first go through patch the road, crack fill the road, do 2 layers of oil and chip then microsurface. The road has reflective cracks in it within a couple months and a year later looks like it did before they touched it.
Dustin Pryde they add new oil
Please see my General replay above. I partially agree. Way more RAP in new mixes than ever before. Hopefully, you get a better understanding of the Heater Repaving process...and its benefits.
Cheaper to dig the road up
Please see my General replay above. Definitely much more cost-effective than a rebuild.
If they are recycling the asphalt then why are there trucks loads of it feeding the paving machines??? I see more costs then savings.
10% new asphalt mixed in
Please see my General replay above. Hopefully, you'll get the proper understanding of this process.
looks very cost effective. haha
went about ten meters and put a load of fresh ac through it so what is it recycling
This is cheaper then repaving?
nop way more expensive like 50 to 60 % more expensive . anyway that is my area
How many BTU is something like that?
Please see my General replay above. I could get accurate energy usage, if you'd like.
Would some explanation of what is going on be to much trouble

All roads should 10'' of reinforced concrete, One and done.
You don't want to have to pay for it! many times more than Asphalt!
@@mikemakuch2824, I agree, but this bullshit of laying down 3'' of asphalt every 3 yrs is getting old, lol !
Nothing worse than the noise of driving on a concrete road, badump, badump, badump, badump, sends me to sleep.
@@dougborrett3566, They should make that noise into a sleep sound tape !
Here in the north east concrete roads do not work, the frost heaves them and breaks them up then you end up with a mess that’s hard to deal with.
Looks like an enormously excessive amount of energy to relay two inches of pavement. This looks costly, slow, inefficient and still needs large amounts of virgin material.
its cutting trucking, virgin material and time. one pass versus 3 if its mill/pave
You have no clue how much fuel an asphalt plant uses to produce a truck load.
Please see my General replay above. Hopefully, you get the whole picture of Heater Repaving. It's actually more cost-effective, same pace, and ultra-efficient than typical paving operations. Obviously uses far less virgin materials. That's the point.
This is a money shit process. I've seen a similar process back in the late 80's in my hometown. It started off with one truck with fresh asphalt to load the machine. The repaver would remove the old asphalt and auger it into the dump truck. When full the dump truck would get in front of the paver where the old material would be loaded into the paver, reheated and applied to the street. A simple and efficient operation. One dump truck, one paver, one roller and a propane truck to keep everything fueled.
Please see my General replay above, for a better understanding of Heater Repaving. You may be referring to Heater Remixing. Different.
I thought recycled asphalt couldn't be reheated again and could only be paved cold.
That process doesn't work. Looks terrible a couple years later.
Please see my General replay above. Where are you located? Interested in seeing if it was a Cutler Repaving job. It does work, or Agencies wouldn't still be using it year after year since 1965. I do agree that wearing course specification can be improved to give better appearance/performance. I'm always pushing for higher AC Content. Beauty of Heater Repaving is that recycling takes place and the overlay lift is kept separate. Compacted together. "Looks terrible" has more to do with the specified new asphalt from the hotplant.
@Chet I saw the process with my own eyes moron. And I saw what the road looked like 6 months later.
@@kevingipson6810 No need to get upset with the others’ comments. Where was your experience. Was it a Cutler project?
Hell of a lot cheaper than wayne do it I can promise u
looking for a Job for paving roads
Why is it with road work there always seems to be more people standing around looking at stuff than people actually doing stuff?
Please see my General replay above. True. Highway project. THis was start-up - not really representative of the project. Many DOT spectators.
Soy espejo de la resicladora.
Y nadie sabe el proceso asta Kelo experimenta de frente
It looks like a very expensive prosses
Clearly the top couple inches have already been milled and millings removed. First 2 machines shown in this video are not the beginning of the entire process & only heat up base layer, next machine scrapes old asphalt surface and mixes in the new asphalt or old millings that are brought in by dump truck, the final machine is the actual paver. Thing is, it's proven that 100% recycled asphalt surface won't hold up as good as new asphalt. Might save money in the short term though.
Please see my General replay above. Close, but you are referencing a Heater Remixing process. This is different. 100% recycled wearing course is definitely a bad idea. Our finished surface is new. Bottom half of the section is recycled in-place. Machines apply the two layers separately. Compacted as one.
How come they keep going over the same spot
wasting money. cutler repaving uses one preheater and one scarper/paver. thats all that is needed
Please see my General replay above.
Wow must cost a fortune to do a road like tis...profiling and filling with new asphalt is the only way to go. Looks like they've broken thru to the road base and I bet it became patchy and soft in areas. The problem with so much heat that it penetrates below the asphalt and if the recycled asphalt doesn't get to the right temp and breaking thru to the roadbase which in turns will break thru the recycled asphalt eventually as it's now soft. The depth of the new asphalt looks rather thin by the look of the cut to the existing asphalt. just my own opinion
after the first preheater goes over an area you can drag your boot across it like its sand
Actually they add a 10% mix of new asphalt as well as refreshing the tar content with a percentage of new tar blend it and re lay it on the road and compact it. The extra burner is probably a waste of time and fuel...the new lift of recycled asphalt is actually higher and thicker than the old road next to it after being compacting.
@@robreesor5011 out here they usually come with what's called chip seal back east, out here they call it fog coat. And on higher traffic routes iv seen a layer of finish grade asphalt on top
Please see my General replay above. Hopefully get a better understanding of Heater Repaving.
Anyone who lays substrate this thin, is in the take you to cleaners.
Please see my General replay above, for better understanding of Heater Repaving. It is a mid-level Pavement Preservation technique. Widely used.
It seems that under the asphalt is just dirt. Wtf
Please see my General replay above. Video shows the takeoff to start the day. We were actually widening the roadway right there. Overlaying base course. The rest of the project was different.
Is the camera man drunk?
Just use a Apm and this is super slow not efficient at all for the length of this video could have put in 200 tons of asphalt
The film was half over before the top coat started they don't seem to want tons they seem to be paving thin.
Please see my General replay above. Far more cost-effective and efficient than Mill & Overlay. Video doesn't capture the whole project. Same pace as conventional paving oeprations.
Ridiculously overcomplicated and inefficient. Just mill off the old surface and replace with new. The old material can be reprocessed in a dedicated facility under controlled conditions.
Sometimes the really bad roads are in fact milled and then paved using this method, However, most are just paved over as is because paver used here is a recycle machine meaning a few inches of the top road surface is scarified and then recycled/mixed with the new asphalt to the main screed.
Almost all asphalt mix used today is of a very high recycled content. Properly processed recycled mix is indistinguishable from mix made with virgin materials.
But yeah, it should be handled by the proper facility.
@@scottbc31h22 rap roads dont hold up as well as virgin materials
Please see my General replay above. Hopefully you get a better understanding of Heater Repaving. Far more efficient and cost-effective than Mill & Overlay. No need to mill and haul them off and then sell back to the customer in the new mix from the hotplant. Recycling that RAP in-place, is no different than the trouble/expense of an off-site processing facility. Old-school thinking has gotten our roads into this mess.
This process seems redundant, and a slow process and way too much equipment and labor. What's the purpose of milling the surface if they're recycling the surface on-site. Here we mill the surface and haul the tailings to the hot plant where they use a percentage of the tailings into the hot mix and the same trucks haul the new mix to a single paver where it's placed then that truck gets reloaded with millings, loaded both ways.
Noticed when the camera got to the end of the line that the last rig was sitting on prepared road bed. A proper road bed would have to be excavated at least a foot deep and layered with several grades of gravel, each layer rolled and compressed before the next. Then covered with an approx. 4" lift of asphalt. That lane will break-up in a very short time with more tax payer dollars spent fixing the first cock-up.
Please see my General replay above. Hopefully get a better understanding of Heater Repaving. You are referring to a complete reconstruction. Hardly any Agency is equipped for that anymore. Old-school thinking got our roads into this mess. Time to get them out.
At the speed they are moving, this does not appear to be a financially judicious operation.
Please see my General replay above. Video incomplete. Same pace as typical paving operations.
be more efficient if you didn't have 15 people standing around watching or are they there for training purposes. some of those there looked like they could use some exercise.
Please see my General replay above. Haha! Video is take off beginning the day. Many DOT spectators.
Seems like a slow ass process to me
It does look that way and it is slow compared to the speed of laying fresh on a prepped surface. However when you count the time normally spent ripping up the old and trucking all new product in, the slower pace of this process is still fast compared to all the typical steps put together.
What a waste of money !
Please see my General replay above. Hopefully you get a better understanding of Heater Repaving.
Jesus!! Really. What a waste of time and money
Please see my General replay above. Hopefully get a better understanding of Heater Repaving and its benefits. Old-school thinking got our roads in this situation. Time to get them out of it.
I’m from Mexico and want to use them to make roads who can I talk with ?
