Asphalt is the black, tarry material that’s often used to pave roads or fill in potholes. Your neighbor might decide to coat his driveway in asphalt.

Asphalt is a popular substance for paving roads, parking lots, and even airport runways, because it’s sturdy and easy to repair. When old asphalt roads are torn up or repaved, the asphalt can be reused in new highway or road projects. Asphalt is usually manufactured from oil, or petroleum, but there are more ecologically friendly ways to make it, including using molasses, rice, or potato starch.
