Asphalt used on road surfaces are byproducts from fossil fuel. With the ultimate goal of eliminating the use of fossil fuel to combat climate change, are there any good alternatives for road surfaces? I don’t think I’ve ever heard of a viable replacement of asphalt in the works, or even a plan to replace it in any environmental discussions before. At least, not enough for me to notice.
Extented question would be: what are some products derived from fossil fuel that are used in everyday life, but still lack viable alternatives you don’t see enough discussions about?
While it’s not a full replacement the raw materials making up the road surface can be reduced. Here’s an example where books were recycled into the road surface - http://news.bbc.co.uk/1/hi/england/west_midlands/3330245.stm
The green alternative to Asphalt existed before Asphalt in the form of Rail Roads. “Green Asphalt” also exists and is currently used for walking trails and biking trails, though it consists of recycled plastic and rubber, so technically it isn’t “asphalt.”
