While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.

The answer to whether or not you need to get a permit before you start your driveway can vary widely based on local ordinances and the scope of your driveway ideas. In most urban and suburban areas, a permit is needed before building a new driveway to ensure that a homeowner is using safe materials and proper drainage practices while designing and constructing a new driveway. In some rural areas, a homeowner may not be required to apply for a permit. When building a new driveway on your own, always check with your local building department to see if you need to request a permit. When hiring a driveway contractor, verify that the right permits are being used before driveway construction begins.

Gravel is one of the few driveway materials that can handle rain the second it’s installed. Unlike asphalt, which needs days to set, or concrete, which requires weeks to cure, gravel is ready as soon as it’s compacted. It’s naturally permeable, allowing water to drain straight through—with no risk of pooling or surface damage. Gravel driveways are one of the most affordable, at $1 to $3 per square foot, and can also last upward of 100 years.
