Roads Can Be Recycled Forever, Why Don't More Cities Do It? | World Wide Waste | Business Insider

Asphalt pavement is one of the world's most recycled materials. Its ingredients can be reused over and over, and recycling it is cheaper than making it new. But regulations often limit the recycled content of roads to around 30%. We visited a company making 100% recycled asphalt to see how they do it.

In 2011, I was living in Joplin Missouri. We had an F5 tornado come through town that destroyed hundreds of homes and hundreds more with roof damage. The landfills in the area were overwhelmed with all the debris. So the decision was made to recycle all of the roof shingles into all of the asphalt needed to repair the city street. The city saved thousands of dollars and the streets are fine.

The reason you can recycle metal is because metal grows very fast. Those tiny crystals grow immediately below melting point and it reverts back to order, to solid ... after you grind it to a powder and melt it. Now try the same with polymer chains. Bitumen or plastic or whatever. Polymer chains don't just grow back when going below melting point. They need very specific conditions to grow and you cannot recycle plastic or asphalt like you can recycle metal. The recycled material suffers partial degradation and the degraded chains cannot be separated and they contaminate the material and change it's properties. To lower the contamination level and mantain material quality, virgin material has to be added to the mix. It will NEVER work without adding virgin material

[@M3rVsT4H]

@@georgeyoutube7580 Did you watch the video? The fact is people ARE recycling asphalt. So the question of whether it can be done is moot at this point. As for plastic, that's a very broad term for a range of products. Some of which are 100% reusable, like PE, PET, PP, PS, PLA, etc.. I've been recycling HDPE at home for years, and we're starting to see consumer grade recycling equipment become more widely available. The plastics that can't be reused, you can use pyrolysis to turn them back into flammable substances for other uses. The word recycling covers a lot of options and I feel you're limiting your thoughts to simply reusing products, but any process that creates a new product from an old one is recycling.

[@georgeyoutube7580]

@@M3rVsT4H well i worked in plastic industry. And you can recycle anything if you use broad terms. We managed to recycle biodegradable plastic. The client wanted to recycle the waste his factory produced. It can work to some extent but it doesn't really work cos the more recycled material you add to the mix, the more waste you make cos the final product start to fail and be non compliant in strenght and elasticity mostly. Sure, you can find another product to dump the recycled material, another technological process and you can recycle. But recycling asphalt to asphalt does not work without adding large amounts of virgin material. And it's stupid to try cos you compromise durability then you just doubled the amount of material you need to dump if the road lasts half as long

[@M3rVsT4H]

@@georgeyoutube7580 I think as more people use it for more things, the term recycling is becoming broader. We will likely see increased use of more specific terms like reused, upcycled.. etc. I'm no chemical engineer but my own thermoplastic recycling has been successful. And I've seen the pyrolysis work. But as you say, it depends how you want to define it. Obviously one must factor in consumables used in the process etc. If this video presentation is to be believed, this company is 100% recycling asphalt, and the only virgin material added was the Paraffin used in the process. And if they've been laying it for 11 years, there should have been ample time to measure the product's performance.

That's the problem with asphalt in general, it looks all the same on the outside, but to characterize the binder's actual quality, we run performance based tests using machines like a Dynamic Shear Rheometer and Bending Beam Rheometer. 100% RAP can be used for parking lots and low volume roads, but wouldn't be suitable for highways since it has less relaxation capabilities than its virgin counterparts, and would pothole and fail faster than a traditional counterpart.

Another really great video! I know another large hurdle in the US is regulatory -- most states have an upper limit set for what percent of highway pavement can be recycled (either from pavement or shingles). I'm curious if anyone knows what other uses there are for the crude oil fractions that would be replaced by green bitumen -- if we don't use those fractions (side products from fuel distillation) for bitumen, where does they go? Are there other uses that are also recyclable?

[@nimrodbegg123]

It's not regulatory, it's specification e.g. quality. What's not being mentioned is that rap is of a lower quality then virgin. Old bitumen is more oxidised so it's lower quality then virgin as more of the oils in the binder make it flexable are gone. So you still need to add new binder. What's also not mentioned is the crushing of the rap makes the stone portions smaller so it's not optimal for large stone size mixes. Finally you can't heat it to the same tempature as the bitumen in the rap oxidises as it goes through the burner if it's hoter then 180degree c. So yes you can recycle it but not at 100% for main roads etc. It's also normally a pig to hand work so not great for small jobs either

State highways really wouldn't go beyond 30 percent due to aged binder concerns. Also adding volitiles to the mix rather then the binder has issues, as it's lower softening point can negatively impact the life of the mix, and it's reslience The crushers do smash stone as that what they are meant to do, and the rap comes from profilers that normally pulverise the pavement to shoot it into trucks. 7 years of playing with asphalt mix and asphalt plants teaches you a wee bit about. 100 percent was something we could do but the quality issues on a product you had to warranty was a issue Also some countries use units that actually make sense and bitumen as a whole tends to oxidise at or near 180 degree c

Theoretically so. The most efficient way is to recycle it in place. Unfortunately, that doesn't work forever as along the time the stones will be ground to dust and the asphalt loses some of its strength. Of course the rest could potentially be used in some other place, like your front yard. You can also use slag and other materials as asphalt aggregate - just ensure it won't cause problems for car mechanics (it really can, ask for more information from Finland).

Most states use recycled crushed asphalt mixed with gravel as a base layer for roads they also use recycled concrete for base layer. So now if they use recycled asphalt for new pavement ontop of recycled crushed asphalt their could be zero waist

[@dand3975]

The used crushed asphalt is never wasted like this video suggests. It is used in temporary roads during bridge replacements, used on steep side slopes by bridges on county and township roads. Some townships use the recycled crushed asphalt as shoulder material. If it is available it makes a great private driveway, it lasts longer than gravel.

[@gc1172]

The area I lived in up until this year recycled all of it with a limit on percentage for highways based on designation such as interstate, US highway, state, or county/city as each has its own issues in the hot and cold weather and base situations. However; that is a benefit as that left an amount for use in parking lots, driveways, and other applications without those needs at a lower cost. Otherwise you are paying more for your driveway for all new when all recycled does just as good.

[@stefano101]

The main reason, especially in modern countries is because of specification. When material is recycled, all types of asphalt get mixed together; but when you design a highway vs. a park pathway the requirements and durability are very different. In Canada and the USA, certain project have very specific requirements and thus recycled materials may not meet spec. But for lightly travelled areas. RAP should be used in greater quantities for sure.

I love this idea so far. The only hurdles still to overcome are the blue smoke and the paraffin oil. The filtration process for the blue smoke appears to be working better than expected. I wish that there were a natural alternative to the paraffin oil, which would also help to reduce any emissions during the recycling process. Like all good ideas that will benefit humanity for the best, there will still be those special interests that don't want to have their precious profits affected. This will cause periods of lobbying where it will make this process harder to establish itself sustainability, in an region where a special interest has an incredible monopoly. I just hope that the courts and the EPA don't fall under their corrupting spells of greed.

Before 1990 torn up pavement was just dumped. In 1990 California required all underground fuel & chemical tanks be replaced and the process was generating many many many many mountains of toxic contaminated pavement & backfill. So the state had the University of California to look at the problem and they invented the process where old pavement was crushed down to gravel and they built a soil burner on a simi truck flatbed so the crushed gravel & backfill was put on a conveyor belt which went thru an oven & the hydocarbons were burned off and the gravel & backfill was ready for re use. Thanks California! !

The 90% is I'm guessing 90% of asphalt replacement is from recycled mixtures (of either 30% or more). Does that make sense? Analogy: norm of 30% water for a drink let's say instead of all fruit juice. Green company wants all of the drink to be 100% water. Already 90% of people drink the mixture of 30% or more of water, and not fully fruit juice. Hope that makes it easier to understand

[@jamesruth100]

It's not necessarily contradictory. The way I understood it is that 90% of old asphalt sitting in storage gets recycled but that every time they lay asphalt the mixture is comprised of 30% old and 70% new. This company is claiming to use 100% old for their mixture, rather than a 30/70 split.
