More On Rubberized Asphalt Roads

[Bruce]

I did a little more digging around the Internet and came up
with the following figures:

1 tire = 10 to 12 pounds of scrap rubber

Instead of scrap rubber, 1 tire can also produce 1 gallon (3.8 liters) of diesel fuel.

Therefore, a large system that processes an average of 500 tires per hour can produce 5,000 to 6,000 pounds of scrap rubber per hour.

According to State Of Arizona specifications, it takes 1,500 pounds of crumb rubber added to asphalt to produce one lane mile of 2-inch thick paved road.
Arizona also says that two inches of rubberized asphalt costs the same as four inches of standard asphalt, but lasts twice as long. Crumb rubber can also be added to road patch mix.

It takes 210,000 to 300,000 pounds of crumb rubber to provide the base for
a gridiron football or soccer field.

Thanks for that. I will pass this along to the Minister of Works of T&T (Jack Warner). My road was recently paved and you really wouldn't know it... the main road along which I drive to go to work has "ripples" in it...somehow they cannot get the asphalt to stay put.

Did your research tell you how much a processing plant would cost?

Is this natural rubber or synthetic?

Recycled Rubber

Is this natural rubber or synthetic?

The rubber comes from ground-up discarded automobile tires. Therefore,the rubber is natural, with whatever is mixed in when the tires were first produced.

As far as I understand...summer tires are real rubber and winter tires are synthetic...

LOS ANGELES (KABC) — Getting a hybrid or other fuel efficient car is one way to move away from a dependency on crude oil. Selecting what tires you put on your car is another.
When we think of oil, oil prices and oil consumption, most people probably think of the gasoline they put into their cars.
But petroleum is also an ingredient in many other things, like tires. Most tires aren’t made of natural rubber.
“They are made of a lot of synthetic rubber, a substance called carbon black, and other petroleum-based materials,” said Yokohama spokesman Fred Koplin.
As the world looks for ways to use less oil, Yokohama is showing off a new line of tires that aren’t made from crude oil, but the oil in orange peels.
“We eat the good part, and you have the peel left over. We take that, natural rubber, and we create a tire that has 80-percent petroleum-free content,” said Koplin.
Yokohama says these are the greenest tires ever produced, and that they’re just a bit more expensive, $3 to $5 extra per tire. They also have a special liner that keeps them better inflated, so theoretically they’ll help with fuel economy too.
The primary applications for the new orange tire right now are hybrids from Honda and Toyota.
But they’re available for other cars as well, like the sporty Mini Cooper.
“For a ‘green’ tire it performs well, and for a performance tire it’s truly green,” said Koplin.
They even use orange-based racing tires on some Porsche race cars.
Most would agree that making things out of organic materials is better for the environment. But the concern is that using something that’s thought of as food to build non-food things would run up the price of food.
Well there’s no danger of that here. What they say is that when orange juice is made, the peel of the oranges is just a waste product.
This green theme is working its way into other car parts too. The Ford Escape Hybrid has seats made from recycled plastic.
And Lexus is introducing interior plastics on some of its cars that are both recycled and recyclable. These innovations make so-called green cars that much greener.
But for all kinds of cars these new tires can help them use less oil, not just in the tank, but on the pavement.
