Asphalt is commonly referred to as blacktop or pavement. Asphalt will cost between $2 to $5 per square foot to install. Concrete, on the other hand, starts at $4 to $6 per square foot and can cost as much as $15 if you add some of the available finishing options. Asphalt is also cheaper and easier to repair and maintain than concrete.

Areas paved with asphalt require more maintenance than those paved with concrete. As a result, there is less need for repair crews to handle maintenance of concrete streets and parking lots. This means less congestion and disruption to work areas, and less danger to road crews and drivers alike. Rigid concrete is also more durable than asphalt.
