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?

As with all equations in civil engineering, it’s not really derived from physics so much as it’s the curve that best fits the data.

It’s kind of interesting in that way, because it’s an implicit declaration that when shit gets really heavy (pun intended), we trust empirical observations more than we trust our own theories of how things work.

I think it’s a great example of coming back to the roots of science in measurement, as a practical humility we must take seriously because everything civil engineers do is high stakes.
