No - asphalt is bound together by bitumen, a sticky, waterproof byproduct of petroleum refining.
eg: You don't get asphalt without bitumen and you don't get bitumen save as a byproduct of a massive amount of fossil fuels being pulled up .. and inevitably increasing the amount of CO2 in the atmosphere.
