Luarbiasa teknologi Thailan baik pembuatan jalan maupun rell Kereta api. Penghematan biaya dan waktu. Kapan Indonesia ?? Pasti bisa lbh hebat lagi ya pak Jokowi
That Chinese concrete road building machine could save the U.S. taxpayers billions on road repairs, why don't we use them. Instead we tie up traffic for months laying roads that fall apart in less than 5 years.
Bonsoir, je reste émerveiller par le génie des hommes, c'est incroyable ce qu'ils peuvent arriver à faire, c'est fou. Tout cela sorti de l’esprit d'une multitude de femmes et d'hommes qui ce sont creuser la tête pour arriver à créer de telles machines, le résultat c'est presque parfait.
I know it sounds really stupid, but they do that to cover concrete so it doesn't dry out to fast as well as keep the heat off it. After that beutiful job is done, if it's to close to 40*F they will cover it with burlap just like to so it doesn't freeze
No wonder the unemployment rate is so high.some of these machines might make the job easy and quick but they also only make the owner operators rich at our expense.
I do not see where the machine is adding it in this video. I seen concrete paving here on the highway. They put in a crisscross layer of large rebar in the mid-section of the slab. I seen where dowels be used to connect any joints.
Bapak menteri Perindustrian tolong rencanakan buat mesin2 hebat yg dpt diaplikasikan buat jalan, KA. Terowongan, bandar laut mesin pengolahan tanah dan panen. Saya yakin menteri perindustrian kita ini orang hebat memiliki visi yg luar biasa
I do not see metal bars to help make the concrete stronger. This is a huge mistake. without metal bars the concrete will crack and the work wil be ruined.
Did you even look at eh Concrete they used? That is 10K psi concrete. You could set off a 30lb satchel charge on that shit. All It would do is blow the dust off. It's that strong. They use it on Airport runways...
At 6 : 27 union Job This is what i did for over 41 years , I80 , tollway 294 ,290 ,rt 53 ,Rt 83 tollway 355 and so many others , i can not remember them all .
pretty much yea. There is so much to building and maintaining the roads that we drive on every day. I did not realize we lay down *that* much concrete for a highway >.< yikes the machines themselves to lay down those highways, we couldn't lay them down manually like those machines. amazing machines. great video. thanks for creating & sharing 😊
These machines can be said to be good in those countries where human labour is costly... like Europe, US. But in Asian countries, manual labour is budget friendly if project is not time-restricted. However, for accuracy and final touch humans required even for such enormous machines. Above all, It is good to see that world is improving.
Ok, to be fair, there *is* such a thing as ancient machines. Big Crude machines : Ballistas, trebuchets, catapults, waterwheels, chariots, ships! More refined machinery : Road Meters (an odometer, basically, used in roman road building, invented by Archimedes in 3 B.C.), spirit levels, grinding machines, etc.. As we move up into the middle ages, we get stuff like Grandfather Clocks, Advanced ship navigation tools, advanced looms, church organs, bicycles, and so on. But a machine with an internal Combustion engine and hydraulics, is by all measures, a modern machine.
Brilliant machinery.Here in the UK,if they fill in some potholes it takes days,then when it’s finished it’s C&@!. I won’t even get started on the “loose chippings” which are early 1900s technology.
The first clip of the curb making is very smooth and clean, because they are adding wet cement slurry to the front of the hopper to prevent voids from forming in the aggregate. There was another machine in another video that used a spinning roller, and it left big gaps between the chunks of rock, and seemed like very poor quality compared to this one.
I always thought channels were precast. We have some concrete roads but they are usually over soft ground where base layers cannot be relied upon to continuously provide a bed. I used to work as a safety man on Tampers in the UK. Never really thought about how they laid those high bank corners on race tracks
They used to use lime to stabilize the ground before paving. This was laid down a good bit of time before the paving took place, and was forced into the ground with a machine with large 'teeth' on it's wheels. It was similar to a pavement 'packer' machine, but it had 'teeth' on the large cylinder. I know this, because I worked at a lime plant where the state picked up the pulverized, powdered, limestone. This was mixed with the soil. The limestone powder had a hardening affect on the soil. The truck's were tank style 18 wheel trucks, and they had a distribution tube, that was attatched to the main exit port of the tank. It was pumped out via a pneumatic/vibration system. to the best of my knowledge. I don't think this is used anymore. I have seen many road construction projects, and none of them have used this for the last several years. I have also noticed that the pavement that is laid down is not as stable at it used to be. I has to be repeatedly repaired or repaived.. The limestone 'powder' was the main element in hardening, or firming up of the soil. The main thing about the limestone powder, was, that after it was mixed with the soil, any moisture caused it to harden, or firm up, causing the soil to become hardened. This made a perfect bed for the asphalt to be laid down upon. There were hardly ever any problems with potholes or any other problems with the asphalt. I is a waste of money on any State or Country's behalf, if they don't use limestone as a base layer hardening agent, to solidify the soil. I live about an hour from Talladega Motor Speedway. I remember the re-paving just a few years ago. I'm not sure if they used limestone powder to support the asphalt or not. If they didn't, I'm curious as to what they did use.
I asked the same question when my patio was poured, was told that rebar has been replaced in some situations by fiber mixed into the cement at the factory.
