@@pippipster6767 It's due to the kind of vehicles we currently use. Diesel and petrol destroy tarmac as does engine oil. Spillages from vehicles are a big cause of potholes as it eats away and breaks up the bitumen.
@@FoodieReviewdie While it's true that petrol and diesel break up bitumen as both fuels act as solvents, leaks of fuel are not common in modern cars and when it occurs the fuels evaporate in most climates. The bitumen will melt and heals itself when exposed to such solvents. The greater problem with roads is simply down to increased usage which puts stress on roads. Electric vehicles will cause just as many problems over time and this is why maintenance will be required for as long as we have roads. There are technologies being developed to further improve the ability of roads to self heal but there are limits to all materials. The greatest problem in recent times has been a mixture of underfunding for maintenance (and corruption in how tis money is spent), paired with poor quality repairs. Many road crews are told to do a quick patch, but a few years go by and this patch quickly degrades and further damage is done to the subsurface which then requires even more work.
Sort of irrelevant. Only one tire at a time would be rolling over the mosaic. 3 wheels would be on regular pavement. You wouldn’t even notice even if it was as slick as ice.
I used to work on a road crew, when the asphalt cools it does look a lot more seamless. Additionally, a few days of UV radiation from the sun blanches the color further. After about a week the sections hit by the Infrared tend to look like the rest of the road (but with fewer cracks)
Not only that, but he used concrete to patch an asphalt road. That's a big no no. The concrete will expand enough when it's hot out and cause the area around it to break up making the pot hole bigger than ever. Great job.
@@thead9 Actually no. I've worked with both and that is simply not true. When asphalt gets hot it becomes pliable. You do know that asphalt roads are placed on top of concrete right? Asphalt roads have more cracks in them because it's asphalt. When it gets hop, instead of expanding the way you think it does, it becomes pliable. This means vehicles driving on it, will push the asphalt down, which it can't go too far down because they only put a few inches of asphalt on top of the concrete. Since it has nowhere else to go it shifts outward to the side causing ruts in the road. This eventually leads to pot holes. Most of the cracks you see in asphalt are usually where the spacers in the concrete beneath it have been either destroyed or worn away with time, or the ground beneath the concrete shifts or gives way and sinks, and the asphalt when hot is being pushed into those cracks.
every area of our lives need this repair and reforms of wonderful science tech engineering minds, including of course the most basics of roof, medicine, education food.
In Poland 50% of roads needs to be repaired but when one hole in road got repaired its got fastly destroyed again because they use crappy materials or they are just amatours so this inventions will be really good and useful in Poland
Heaviest traffic on a roman road was a chariot or wagon weighing at most 2500 lbs. Most traffic was foot traffic, also most of the empire was in temperate zones with no winter weather to speak of.

Think of the money one could make just with driveway repairs! My small driveway is going to cost 10k to replace and I bet this would be closer to 6 if even that.
Yes, the mosaics in Pompeii survived for thousands of years, under meters of ash, and without ever being driven over by a 20 ton truck. Therefore mosaics are the way to go. Pretty though.
Yeah, those mosaics look like they're doing great. There's a big difference between ancient roads where most traffic was foot traffic and modern roads.
@@Cecil97 Yeah I'm with you man, the road should be consistently repaired. The fact that it's done for free is irrelevant. Imagine if someone did free surgeries, and did them wrong. "Well, they were free," some people might say. Ok. They were still wrong.

Oh these mosaic plotholes would make perfect material for geocaching riddles.
We need more workers to keep the roads smooth my little brother died on a motorcycle because of a crack in the road it has to be more we can do to make sure these roads last a lot longer than they do
You can't blame people for driving with studded tires when it is March 12 and it is snowing outside right now where I live like it was the middle of a winter.

As long as cities continue to use asphalt to pave streets or highways, repaving or fixing potholes will be necessary very frequently. I've seen repaving the same roads at least 3 times in a 10-12 year lapse. Use concrete with rebars, like on overpass, and it will stay like brand new new for many years with little or no maintenance.
Here in northern Indiana the concrete roads are just as bad as the asphalt ones and much harder to repair. So they may be better in warm places but the freezing and thawing destroys all roads around here.
The gunk that is left in the hot tanks used by roofers is a fast and long lasting pavement patch. I used to get the roofers to dump what was left at the end of the day in the parking lots to provide a fast and lasting seal of the potholes. But highway engineers are not inclined to try anything new.
