So where exactly will the asphalt for the roads come from? Right now probably 70-80% of lane miles are asphalt (and portland cement concrete isn't exactly a green product).

Nothing political about it. What will these big beautiful roads be built from?
Does making asphalt roads include burning the tar or can it just be mixed with the aggregate and rolled out?


You generally have to heat it up to around 400F, mix and then roll out. Cold patch used to be mixed with gasoline to keep it from setting. When the gasoline evaporated, it would effectively set but that's a big no-no due to the emissions now.

The problem with recycling asphalt is as it ages, the lighter components evaporate away and it becomes brittle, so while you can recycle it to a small degree the recycled asphalt still needs fresh asphalt added and it doesn't hold up as well as virgin asphalt pavement. Also, you can't control the agregate as you are stuck with whatever was in the original mix and that mix is broken up by the milling process. Usually, recycled asphalt is used for parking lots and light duty roads.

India is having good success with recycling plastic for roads.


First, the plastic is not the binder but an aggregate replacement (it replaces some of the sand and gravel). (They do similar with ground up tires)

Second, plastic is made from....crude oil. While there is a small amount made from plant sources, it generally doesn't have good long term durability. In fact it's promoted based on the fact that it breaks down fairly quickly...not so great for a road where you are shooting for a 20-30yr lifespan.


This article is from 2016 so the road is now 18 years old. "Jambulingam Street, Chennai, is a local legend. The tar road in the bustling Nungambakkam area has weathered a major flood, several monsoons, recurring heat waves and a steady stream of cars, trucks and auto rickshaws without showing the usual signs of wear and tear. Built in 2002, it has not developed the mosaic of cracks, potholes or craters that typically make their appearance after it rains. Holding the road together is an unremarkable material: a cheap, polymer glue made from shredded waste plastic."

From the picture that is a small local road with negligible truck traffic.

How much nuclear fuel is there?

"As of 2017, identified uranium reserves recoverable at US$130/kg were 6.14 million tons (compared to 5.72 million tons in 2015). At the rate of consumption in 2017, these reserves are sufficient for slightly over 130 years of supply. The identified reserves as of 2017 recoverable at US$260/kg are 7.99 million tons (compared to 7.64 million tons in 2015)."

The problem is that the current long term prices is $78/kg.

The elephant in the room is waste storage. Some suggest using breeder technology to reprocess the fuel. But, there are few breeder reactors--and it is cheaper to mine uranium for fuel than to use this technology. Russia and China have a couple each, with one in China being the most recent.

The point is that nuclear is NOT a renewable energy source.

No body wants to talk about the toxic waste that that ALL the current solar panels are going to be when they reach their end life. There is no money or plan to dispose of that waste safely.

Define 'end of life'.

Define 'toxic'. Nuclear waste is toxic for many centuries.

And, it is possible to recycle panels . This article is from 2017.

I dont think we can go full green energy anytime soon,bc airplanes for example will need FF for long time yet

However for shorter cross country trip electric high speed trains would do better,especialy for people who dont like to fly

But then we would have to hire chinese or Japanese to build it as our leaders dont seem to know how.

China high speed railways

Where do they get power to run,,hydroelectric,wind,solar,etc and now

China already leads in renewable energy

How can they acomplish so much in such short time

China is run by engineers and well educated scientists,financial experts,not by some washed out tv personality science denier.

China is investing in infrastructure,roads,bridges,housing creating jobs for everyone and not wastin money on military no doubt helps.

They're the greatest, just follow the rules though or end up being sent to work camp or possibly just dissappear altogether. Those silly Chinese. Perhaps you should move there.

Lots of high speed train manufacturers out there. Spanish, French, German, Japanese. Spend some time on high speed train transport and you might change your tune a bit.

Have you ever seen any Our News network post positive Truthful facts about China like I just did here?
They cant,why not?
and you wanna brag about Freedom o Speach,seriously.

Oh yes the work camps,
Did you know that Taliban from neigborin Afganistan atacked Tibet China and murdered thousands of civilians not long ago tryin to instal Sharia law?
Why dont western media report on that?
Yet
China still allows ALL religions including Islam and even has 35.000 Islamic Mosques.

https://youtu.be/soPJESgkE5k

Maybe we should have work camps too,so we wouldnt have so many homeless Lol

I talk w many western expats livin in china and they all love it
Plenty o work low cost livin and no homeles junkies,
Its simple China executes drug pushers and life is good

See Reforterfy media travel if you dont believe me
https://youtu.be/yIbmL17P3nc
Or try
Gweilo60 or Nathan Rich or Blondie in China or Mexicanos in china or
Richard Augilar chanel,good luck getin woke

Most americans big egos cant accept that some other system is better
Especialy if it has comunism name,but china uses capitalist system also as the largest number of Bilionaires in the world proves.

What democracy means to chinese

I dont dispute that,
so why cant we build such high speed railways here.?
Its obviously cleaner then burning fosil fuels.
Also
Japanese bullet trains have been trouble free over 40 years running,why are our slow trains so accident prone?
Could be that asians work ethics are better.
