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

The plastics that can't be reused, you can use pyrolysis to turn them back into flammable substances for other uses.

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

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.

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).

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 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.

RAP is great. I’d love to read the research papers for the 100% RAP mixes and how that relates to superpave design methodology. From what I remember, lots of states don’t like using more than 30% RAP on long paving stretches because the contractor can’t guarantee the temperature range for superpave design.

Amen!!!! More power to ya! Even 50 recycled would be an improvement. 70% would be even better. I've used screened millings and covered them with basement wall sealer, and a little sand on top. It sealer soaks in and the sand or even pea gravel stops tracking the sealer. If I can do that asphalt companies have equipment that could duplicate or do what you guys are doing. Again, more power to you all.

Back in the 1970's California had laws that didn't allow the recycling of base rock (ballast). We didn't understand and figured someone in government had a cousin in the gravel business. Also there are roads that are 24" solid concrete that have to be bored and not cut.

It's actually done a lot in my area. They save the piles and reuse them. Theres very specific areas you are to dump at if you have asphalt debris. The real problem is tires. There are countries that don't. I'll tell you the secret to recycling tires... liquid nitrogen. It subjects the tire to such a cold it crumbles and can be pressed through tubes like play dough to be reprocessed. You can even strain the wire out of it via a separator as it passes.

Recycled and permeable roads are the types that should be used widely.

My 350 foot driveway is made from millings. Fresh from a ground up road and parking lot and dumped here. Spread it out and its solid as a rock. Not as good as spreading a hot mix but damn good. Recycling it back to hot mix is no different than making it new. It should all be recycled.

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.

No, usually it means you *are* crazy. Otherwise all the breatharians would survive and the perpetuum mobile inventors would be billionaires.

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.

From my discussions with a man who's father owned and operated an asphalt plant for over forty years he said many municipalities are attempting to save money by using higher percentages of R.A.P. recycled asphalt product, it's certainly cheaper but the rocks become more brittle due to the high temp cooking process and the roads fail prematurely, he said in his opinion it was actually a ruse pretending to try to be green by recycling but the sellers know the earlier road failure rates lead to more lucrative contracts that need to be redone more often. He indicated that using anything higher than 35% rap was an detrimental to the roads longevity. I'm not in the industry but wanted to share my thoughts.

Great job here, I fully support your efforts. Since you have cut of the back end of the business (digging up the aggregate) you should start your own paving company and contract directly with the cities and state and get your dream of worldwide use to the next level. Rather than battle the old ways become their competition. Isn’t that what America is all about. You can lead a horse to water but you can’t make him drink.

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.

the reason fresh asphalt plant has less blue smoke is with fresh they cook the stone first get it hot then add the oil at the end . so the oil never sees the flame . with recycled the oil is being cooked along with the aggregate.
