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?
Asphalt is really highly recycled (though I’m sure at a high energy cost), so at least we have that going for us.

It currently takes about 3 to 6 cubic meters of gas to make 1 ton of asphalt. It doesn’t really matter if that’s new or recycled, and doesn’t include mining and transporting the materials.
