Answer 1

Rubber tyres have more adherence to asphalt than concrete. That is a safety feature when talking about driving. There are concrete roads when asphalt is not viable, but asphalt is preferred for safety.

Concrete will last longer. Much longer. But asphalt is faster to repair and reusable. Concrete might take a day or more to cure. Asphalt is ready in hours. Roads need to be repaired often, again for safety. Sidewalks will not suffer wear from heavy vehicles passing over them, so concrete is a better option as you don’t need it to be grippier for you to walk.
