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?

What ruins the asphalt is the weight of vehicles, and in car-free places, you can see 30+ year old asphalt without potholes or cracks with only minor damage or repairs. If it weren't for the sun making the asphalt pale, you wouldn't know it isn't a recently paved street.

By reducing the number of cars in cities and towns in favour of bicycles and rail, and putting stricter restrictions on the weight of the vehicles, we can make asphalt last WAY longer.

Also, some modern asphalts are more durable than older ones, but I don't know the specifics.
