The World's Most Recycled Material 

Nice

Nice

Great video. I'm curious environmentally what the impacts of asphalt is on surrounding soil. I have a recycled asphalt driveway, and it's ~100 feet from my well. Being a petroleum product and it's usage world wide is pervasive, what environmental effects have their been observed in soil quality or contamination?

All those clips you use on your videos (like the trucks carrying houses or ducks crossing the road), where do you get those? Do you film any of those yourself?

Yeah, now I make several trips down the stairs, and let me tell you how HARD that is: I have to stop eating popcorn, get off the couch, and actually walk 😭 😂

How so. You like that smell????

It’s really good if you live in Michigan

In Dallas in the 1950s the engineers who designed North Central Expressway said that when opened the road would handle 80,000 cars per week. 80,000 cars went down it the first day. It took 40 years of political machinations before it was rebuilt. And traffic still stops on Thursday for the Friday afternoon rush hour.

I have you a notification dude

planned obsolescence

Devil's advocate. If they go out of business, there would be no one left to build the next road or the next highway. Also, the longer lasting ones probably cost more as well.

У битума срок службы очень большой, но проблема не самом вяжущем, а именно что в асфальтобетоне - верхний слой всегда будет разрушаться, даже если по нему не будут ехать машины из-за выветривания и солнечной радиации. современные дорожные битумы на СБС полимере (SBS). Действующие стандарты, например, в Украине, предусматривают для покрытия дорог почти всех почти только асфальтобетоны на таких битумах, а для высокой интенсивности - в том числе ЩМА (SMA) срок службы которого от 5-7 лет.

Civil engineering a solid major

Roads don't magically appear out of thin air.

@@madjack1748 I mean, if you accidentally step on grass enough times then you could make a road.

I can make you pissed about it again. Like the fact that companies purposely take their time to get the most money, or the fact that the government takes a couple hours to check the road before the crew can continue. The most irritating is that companies charge the government more for the same materials they sell to everyone else.

Cement must be heated to 1000 degrees centigrade and more ! Usually using coal in n order to manufacture the cement And f course using bitumen which is a leftover from oil refining and is another toxic substance we put in our roads and then the rain washes it into the soils and groundwater- just like Plastics is leftover gunk from the oil industry and this ends up in our waterways and oceans we make all of these so that cars which use even more CO2 in their manufacture and pump more CO2 when we run them. -- We should have stuck with the electric cars in the towns and suburbs and great train service to go from city to City as we used to do. . We had electric cars at the beginning of the century and there were over 15 thousand electric car charging stations in New York City over 100 years ago can you believe that?

@@sfmc3000 Great points about the environmental impact of asphalt. And yeah we definitely should've kept working with the electric cars. Who knows where we would be today if big business kept investing in the R&D. Maybe John B. Goodenough could've been working on solid state batteries much sooner.

Also it seems like this is like his series on cement so this is just the introduction to asphalt and then in later videos he'll have practical experiments and such to get more indepth (which we saw footage of).

I get what the point of his videos is, but would have still liked him to mention the voc's that the asphalt/bitumen give off. This is another form of aging in asphaltic cement pavements that has to be addressed when recycling them. The more oxidized the binder gets, the stiffer it typically gets. This is one mechanism of asphalt shingles getting hard and stiff over time. It is extremely recyclable though and often just requires adding a lighter portion of oil refinery products to thin it back out and make it flexible and sticky again.

@@sfmc3000 both Concrete and Asphalt pavements take energy to produce, but they save incredible amounts of energy by allowing cars to travel them more efficiently than a dirt or gravel road. Trains ride on steel rails which are energy intensive to produce. Those rails ride on either concrete ties or wood ties soaked/coated in all manner of toxic preservatives. You kind of have to take your pick on what level of environmental footprint you are comfortable with.

Like he said "They don't build 'em like they used to" lol

Cement roads are best and last 100 - 200 years depending how its built. If not romans would have built with worthless asphalt roads that break apart after 1 -3 years and at best after 10-12 years. Petroleum industry funds fake "studies" to run down Concrete roads so they can keep making asphalt sales/roads every few years. Cost difference isn't much. Even if its 200% more the long life span makes the annual cost 3 times more for asphalt. If all roads were built with concrete roads the country could have saved trillions in wasteful asphalt road building racket and most road builders would have to look for other jobs or unemployed.

@@davelawson2564 manufacturing of cement is an extremely dirty process and it uses very scarce raw materials, like sand.

@@Teporame LOL ! asphalt uses small stones. you can make sand by crushing the same stone. The fact that concrete roads last 100 - 150 years unlike asphalt useless roads that fall apart in 2- 10 years depending on road build quality. concrete roads are 10 times more coast efficient and saves tax funds and gives better quality roads

@@davelawson2564 This is very true; actually i was surprised to hear him say that asphalt roads are more economical than rigid pavements (concrete roads) because its just straight up false. A rigid pavement may have a significantly higher initial cost, but its way more economical in the long run as it barely requires any maintenance (if properly designed) and has a way longer design life than even the best designed flexible pavement (asphalt road's design life of approximately 15-20 years is only possible with extensive and expensive repairs)

I remember that I once fell on asphalt walking to school because of black Ice there was a raised concrete curve that had its edge right where my neck was, I probably would have been seriously injured if I wasn't wearing a loaded backpack.

@@garethbaus5471 I had a fall like that once, but instead of my neck, the curve hit right in to the back of my head. Somehow, I escaped with nothing more than a bruise.

@@KruhlSentru oof. Glad to see you made it through alright

disadvantage of asphalt's color, heat island effect in cities

@@r3d0c That's also very true

On a lot of concrete roads here in FL they add black stripes near the white stripes to give contrast to the lane lines.

@@r3d0c - In Japan they invented a special grey additive for the top layer. It reduces heat by about half and makes the asphalt more resistant to water, since Japan experiences lots of typhoon.

@@r3d0c in reality there is almost no difference between concrete and asphalt. The only real difference is between new asphalt and new concrete. But as they both age rate of reflection starts to converge.

I wish they would hold the construction companies accountable to the shit they build.

As an inspector as well I can also tell you that problem usually comes down to money. Complete road reconstruction costs a lot more to do.

@@dimesonhiseyes9134 Though they probably cost less in the long time (reconstruction vs repair after repair).

nice job

@ that is often the case. But road construction is just as much art and magic as it is science. It's always a balancing act between the money you have now, the money you will have later, and time. There are often trade offs that have to be made. I have had jobs where we did a portion of the job as a complete reconstruction. And portions of the same job were just a mill and overlay. Those portions of complete reconstruction cost considerably more. And took multiple times longer to complete than a similar distance with just a mill and overlay.

Part of that is down to maintenance. If you expect a thing to do 10X, but you only maintain it up to 5X, shit breaks.

Here in philippines asphalt is so bad. I dont know if its because of underbudgeting or the weather here is just that terrible.

But the only thing for sure is politician destroy the road and "fix" it just to make name for the public

@@justarandomweeb3220 sadly many municipalities exploit this fact. As explained in this video, the quality of the bitumen and the rock, as well as other additives, can extend the life of roads for many years. HOWEVER, to the untrained eye and those not IN THE KNOW, you cannot tell a high quality paved surface from a poor one when its fresh, but after some time it becomes apparent, but then the same company that laid it down is contracted to maintain it. Not everyone tests, I learned that from experience. Its a constant 'make work' project, that lines the pockets of unscrupulous officials.

The Great Pyramid Erection yup and it’s worse when it 3 months later in Minnesota that it becomes literally 95 degrees f

Similar case here, but with a slight twist. I oddly enjoy civil engineering stuff as an avionics electrical engineer with a phase background (USAF), and while I love what I do, aside for the occasional 14 hour nights with my head in an 1800 page WD under a canned jet, if things were slightly different, I'd be a civil engineer. I went to school initially in the late 90s for Architecture but then 9-11 happened. Since then I've revisited my old interest and realized civil engineering was more of what I wanted but never knew it. Either way, Electrical or Civil Engineering, I'm at least glad I didn't go the architecture route.

Wow

That must have been a treat to watch

I've seen something like that before. It was really cool.

Tarmac

@@crusherven I thought so too. It was one of those elegant engineering wins that solved multiple problems simultaneously.

Not to mention the Roman roads that "are in use today" have been rebuilt and maintained.

I've seen some original 2000 year old Roman roads. They are still very much recognizable as roads, but they are in really bad shape. You wouldn't want to use them with a bicycle, or even pushing a stroller on it.

@@Yora21 right ok I'll grant you that. They are basically walking trails at this point. However the roman roads that people thj k of when they think of roman roads that are "still used" have been rebuilt multiple times. And are maintained quite extensively. I used to work with a gentleman that did it in Italy.

St. Marys St. in Raleigh NC still has a 100+ year old cobblestone base. When it was resurfaced many years ago, you could see what it would be like to drive a modern car on a Roman (like) road. It's very loud, and very uneven. And as long as you keep 40t truck off of it, it could last 1000 years. But you absolutely don't want to use that for a modern road. It's drivable, if only barely, because the speed limit is 25mph. The faster you go, the less control you have as the tires are in contact with the surface less and less.

@@jfbeam a closer example would maybe be a street made out of pavers. They are very common in Latin America and Europe. They are pretty durable but offer very poor ride quality. They use them in Latin America because they are cheaper to maintain. When the road sinks you just dig them up and re set them. After all people are cheap when they get paid just a couple dollars an hour. Materials are expensive.

So, why and how does it fail? Is it possible to engineer some kind of super-asphalt, that doesn't lose quality so fast?

@@ras573 I work for my province's transportation authority and I spend a great deal of time dealing with highways as you might expect. There are a lot of reasons for failure, though the most common in my area is temperature fluctuation. As mentioned in the video, asphaltic pavements are designed to flex, but when they get too hot, they can flex too much (which can result in wheel ruts over time), or too cold, which can result in cracking due to being unable to flex. Most asphalt mix designs attempt to account for this by providing a specially designed PGAC (Performance Graded Asphalt Cement - the binder that holds the rocks together) that meets the temperature requirements of the area. The PGAC is designed for a maximum and minimum temperature in which it will perform properly. In my area, a 64-28 PGAC is common, meaning it can withstand temperatures of up to 64 Celsius and down to -28 Celsius. In areas where the temperature fluctuates less, they may use a different PGAC. In the vein of temperature, another common cause for failure in pavements is due to movement of the subgrade (the rocks and soil underneath the pavement). One common issue is known as "frost heaving", which is the subgrade literally heaving upward due to ice forming in the soils. This can be mitigated by building your subgrade out of materials that are less susceptible to frost. Rebuilding the subgrade is a time consuming and expensive process as you might imagine, since you are not only removing asphalt, but the material underneath it and replacing all of it. This can be part of the reason construction seems to take so long, since they're rebuilding what is essentially the foundation of the road. In a case where the contractor is only removing asphalt and repaving, it takes very little time, generally speaking. Other potential causes of failure often are results of the construction process or the materials used. In my work, we have very stringent standards and specifications that contractors MUST adhere to, that help us get the best product. It's also why contractors charge more to do government work than for say, paving your local grocery store parking lot- because we hold them to a higher standard in order to get a much better product. Main factors that affect the quality and durability of pavements include compaction, percent of asphalt cement (AC) in the mix, properties of the aggregates (rocks and sand) used, segregation in the finished product, and a few other things. Let's start with compaction - we specify a minimum and a maximum percent compaction for the asphalt. You've undoubtedly seen those massive steel drum rollers they use... the drums vibrate and help knit the mix together into a tight, well compacted surface. Compaction is checked in the field by use of a nuclear density gauge, which is placed on the surface of the asphalt and measures the compaction approximately (I won't get into how it does it, but basically it bounces radiation off the asphalt and performs a calculation). It is further checked (much more accurately) by taking cores out of the asphalt. Generally, a set of 3, six inch diameter cores are cut into the surface, removed, and tested in a lab with a series of tests that accurately read how well the asphalt is compacted. Poor compaction can result in moisture getting into the road surface and causing cracks over time. It can also result in rutting, as there are too many voids in between the aggregates, allowing the surface to bow and rut. The reason we set a maximum limit for compaction is mostly because over compacting the asphalt can cause it to crack prematurely from the stress. Basically you're beating it up and it starts to separate and break. Percentage of AC in the mix is important, as the AC is basically the glue that holds it together. Not enough glue, it can cause the asphalt to crack and come apart, allow moisture in, and degrade. Too much glue, and it starts to bleed out the top of the fresh asphalt, which can cause poor traction (since it's so smooth). Properties of the aggregates - This is extremely important, just like compaction. The asphalt mix is designed to have very specific proportions of different sized aggregates in it, from mid sized gravel to extremely fine sand. The mix is designed and tested based on these proportions, and if it passes the litany of laboratory tests, it can be used. The contractor (or their asphalt supplier if they don't supply it themselves), will design a mix that meets the specifications of the project they're working on, and attempt to produce asphalt with the properties laid out in their mix design report. As the asphalt is laid down, occasional samples are taken by a trained quality control (QC) worker. Generally, the QC worker will gather fresh asphalt from the paver as it moves along the road placing asphalt and put the aphalt in a container (often a box). Generally, 3 boxes are filled per sample - 1 for the contractor to test, one for the owner (the person paying for the work) to test, and a third used as a "referee", if the contractor and the owner results disagree. The referee sample is used basically as a tie breaker. If it agrees with the contractor result, then their results are used. If it agrees with the owner, their results are used. Referee samples are not used if the owner and the contractor get the same results from testing their samples. Anyway, back to the sampling process. Once taken, they go back to the lab for testing. These tests check that the sample meet the requirements laid out in the mix design report. If they don't the pavement may need to be removed, or the contractor may have to accept less money for the work. Lastly, is segregation, which is a very common problem and one of the easiest ones to spot. It occurs when the fine particles (the sands) and the coarse particles (the gravel and rocks), get separated while being placed. This can occur due to over compaction, poorly mixed asphalt, or placement methods that are less reliable, like using shovels and rakes instead of a large driven paver. When the aggregates are separated, the surface of the pavement looks very "open", sort of pockmarked and with large gaps in it. This allows moisture in, it can allow larger aggregates to "pop out", wherein they are knocked free of the surface by traffic or temperature flexing in the surface. Segregation is usually dealt with by removing the affected area and repaving, unless it's relatively minor, in which case the contractor may just be issued a reduction in payment. I hope this large wall of text isn't too confusing. If you have any questions about my points, I'm happy to explain myself. Cheers :)

@@davidha44 Thanks for such a detailed answer. I was wondering what book to read this week. I'm joking... What do you see potentially replacing asphalt in the future, if anything? How will roads advance? And I don't mean incrementally, but, what can be done to radically increase the quality, or decrease the cost of asphalt, and roads in general?

Iiiiokoooookkkkkjkkjhhknjjj

I'm looking forward to be one, what advice do you have to someone looking to major in that degree?

@@endingtasks8538 I will give you some general tips for any career. 1) Make sure you like it and know what you are getting into. The best way is to ask a friend or someone you know in that field if they can allow you to accompany them to their workplace and watch them working for a day. Or during "Open days" at schools and universities you can talk to people in that field. 2) Check that there is actually demand and job opportunities for it wherever you live or intend to live. Too many people graduate and cannot find a job.

@@endingtasks8538 What branch of Civil Engineering are you interested in? Remember that most of the time you will be starting as a site engineer. If you live in a hot or tropical country this is literally hell. Aside from sunburn and heatstroke, you can get dehydrated, skin cancer and on top of that sites in general are extremely dangerous because there are no railings or proper safety structures etc because everything is still under construction.

I think schools and universities are crap at teaching.

Yes for the most part, it was correct. There's some things here and there that were incorrect, but that may be due to where I'm located. Overall, it was a pretty good job.

Quite a few errors actually. I was visiting the saint gobain testing labs who own "Tarmac" the company , showed me the pages of mixes for tarmac, weather it's for roads, pavements, carparks, low noise, high or low temperature, they even adjust the coefficient of grip, there is a lot of science in mixing.

@@dogwalker666 that's pretty interesting. Me living in a state that does testing differently from other states, you don't have the luxury of learning that stuff like high/low temp, dampening the road noise stuff like that

@@SweatyPotatoChip One of the reasons the city roads are failing so quickly here is because they were asked to supply a low noise version which they did however the low noise mix failed premituly now the council's have hundreds of miles of new roads that need repair plus the older ones that were scheduled for replacement, they just can't cope.

Also many of our roads have added stuff that makes them somewhat spongy, which makes them more expensive but improves road safety a lot when it's raining heavily preventing aquaplaning.

@@Lucifer_26 and porous asphalt reduces road noise by a significant amount. I bet that even the things that the Netherlands does poorly is still done better than in the USA.

@@trulyinfamous Mostly because we have the luxury of politicians who still have common sense and are generally trying to *improve* the country.

‘If only all teachers could teach like this’ - you mean provide high level information only without any details which one would actually need to apply the knowledge?

mina86 So what exactly is the information that you still require? The volume of asphalt needed for 100m of roadway? The temperature it needs to be to be worked? How to properly grade a curve in a road? How to operate the machinery? The specific chemical additives and mix ratio used to make roadways more durable in the surrounding climate? What materials should be used for the subsurface? How thick the roadway should be? The topic itself was asphalt, not construction.

@@mina86 I think the author of this post meant that the way the content is presented is engaging and informative, something that he or she wishes that more teachers could do.

top dressing

As far as i know, water leaking below concrete isn't good.

@@LeoLeo-qo7yw what he means is the top layer of asphalt is permeable, under that layer is an impermeable layer . Instead of water travelling across the surface to the drain it travels under the surface so no risk of aquaplaning on standing water . Doesn't work where you get frosty weather.

A lot of studies have gone into "permeable asphalt" like you mentioned. The thing is that usually the surface starts off permitting groundwater, but as time increases those pores fill up with dirt, grim, oil, etc and the roadway no longer allows water to filter and drain like it used to, turning it into a normal road with normal drainage properties. We use them a decent amount in California because they are more "environmentally friendly" but most people in the industry know they are just a way to prolong the inevitable.

It has a really nice sideeffect, it breaks the noise in those gaps which makes it really quiet. That is the main reason we use it in Germany on the Autobahn in the cities, even tho it is not so durable like regular asphalt and needs to be replaced sooner.

It's funny I just got back from a job today where the crew were laying down the porous asphalt you are talking about. It's called OGFC here and it stands for open graded friction course. It let water go through the top and drain out from the second lift which connects to Catch basin. Driving on this type of asphalt generally produce less noise which is needed for this section due to animals around the highway that are sensitive to sound.

They started doing that with busy highway ramps here. The resultant texture is actually helpful in rain/snow.

It's super neat to watch but it smells so bad. I'm surprised they don't have to wear respirators when working with it.

How you know?

Sythentic_republic ok, thanks

Because when romans build the road, there's no truck passing and anything that heavier than a horse :((

in germany, when it gets that hot, they cover the roads in really fine, but sharp grave. while the asphalt is hot and soft, cars driving over that road will press the gravel into the asphalt and afterwards the layer of brighter gravel can keep the asphalt below cool. after a few weeks of this a machine comes over to pick up however much gravel is still loose, to be used somewhere else. this leaves a coarse surface on the road, which is great in winter.

We will always use oil, at least for the rest of our lifetimes, and likely quite a number of generations. As you point out, it is used for many things besides fuel. Lubrication, manufacturing, and various other uses will require it's harvesting for quite some time. If we ever do get away from oil as a fuel, it will still be drilled, just in smaller quantities.

Well, because it can be recycled, asphalt would go on for quite some time even if we stopped all oil drilling, but it would eventually run out and then we would go back to concrete, maybe with stone bricks to save on concrete (I guess).

ya but at the same time transportation and energy accounts for like 90% of oil consumption. in the US, roads constitute 350,000 barrels per day while fuel constitutes 9.5 million barrels a day, and you get much more fuel per barrel than you do asphalt

@@raystinger6261 There is a real possibility that we may never run out of oil. As PsychoLucario points out below, IF we reduce our dependence of oil for fuel, the oil will last a very, very long time and we are constantly finding new sources of oil. On top of this, we are also experimenting with other sources of oil, such as oil from algae. Just recently, the USAF flew a four engine jet entirely with bio fuel. This is but one way we may find new sources. There is also a minority held theory that oil is not abiotic, but rather a biotic process, and thus will always give us oil. While this is indeed NOT a mainstream theory, we don't actually know how oil is formed. The prevailing view is that it comes from dead dinosaurs and other decayed life, however scientists don't know the actual process, and are unable to replicate the process. There is always the possibility that we are wrong. The end result is that the idea that we will run out of oil someday is not a foregone conclusion. We might, but we might not.

@@PanzerDave IIRC, most oil is probably formed from dead trees from the Carboniferous, and the fact we can't replicate the suspected processes in a lab is that it requires extreme pressure, heat, and _time_.

My question is - how long is a road ?

@@MrSvenovitch Right you are. Spelling isn't my strongest suit! XD

Nice

Ask an Indian road contractor and he could make it even simpler. Unfortunately those roads don't last a year.

@@echooscar5241 ohhh you know Indian Road Contractor make it Simpler Thnxxxx Echo Oscar you know much about Indians

Cement must be heated to 1000 degrees centigrade and more ! Usually using coal in n order to manufacture the cement And f course using bitumen which is a leftover from oil refining and is another toxic substance we put in our roads and then the rain washes it into the soils and groundwater- just like Plastics is leftover gunk from the oil industry and this ends up in our waterways and oceans we make all of these so that cars which use even more CO2 in their manufacture and pump more CO2 when we run them. -- We should have stuck with the electric cars in the towns and suburbs and great train service to go from city to City as we used to do. . We had electric cars at the beginning of the century and there were over 15 thousand electric car charging stations in New York City over 100 years ago can you believe that?

@@sfmc3000 great knowledge R You Civil Engineer

Yeah, I always thought it was "bi-TU-men." Of course, it really just tar.

@@MikeV8652 - Close but not exactly like tar, though have been used in ancient times to make Asphalt roads. Bitumen is made of different material.

It sounded just fine to my Canadian ears.

@@reillywalker195 I mean, if you're in southern Alberta, your house is probably built on the stuff, no? There's certainly a lot of it around, anyway.

Sounded like he said bitchin

come here to the states where they seal coat the roads. pretty much 'painting' the asphalt. who needs black ice when the seal coat is greasy, it gets wet its an adventure driving on

That's not true. Usually someone spray paints a cock around the hole and plants flowers in it.

I thought that was the standard method. This whole "repairing" concept is just so alien...

the U.S. and Great Britain are "two countries separated by a common language" -- what does "bugger" mean? I watch enough British TV shows to know what "bollocks" means, but I havn't figured out "bugger" yet.

@@rick9870 I believe bugger is a slang term for... Entering the back door, if you get my drift. But used in the context of "bugger all", it means nothing

They call a guy to measure the pot hole at the edges, and then he becomes a meme.

Then, as the concrete slabs continue to move, expand, and contract under there, the asphalt cracks and chips out over each joint in the slabs. Politicians who do that should be horsewhipped.
