Are there any green alternatives to asphalt in development? (sh.itjust.works)

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?

they will often get deformed by roots or depression of the ground quite rapidly

That's true, but more of a maintenance issue IMO. Brick roads do have the advantage that workers can just take some of the bricks out, fix whatever is wrong underneath and put the same bricks back on. Can't really do that with asphalt, which will eventually deform as well.

Asphalt is almost a liquid when it’s hot. That’s a significant advantage in application.
