Driveway Guides. Granite Driveways | Durable, Heavy and Very Expensive! Granite driveways, much like slate driveways, are among the most expensive, most luxurious in the world, requiring skilled laborers and heavy machinery to properly construct.
The two most common options are asphalt and concrete. Asphalt driveways are typically black in color, have an average lifespan of 20 years, and they cost as little as $3/sf. Concrete, while much more durable and lighter in color, can cost closer to $5/sf.
