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?
Kind of a brain dead question. We have much bigger sources of pollution and Asphalt is heavily recycled. We don't have to replace everything that uses oil, just the heaviest offenders.
