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.

Paving is a part of hardscaping, so all paving is hardscaping, but not all hardscaping is paving. Paving involves laying down concrete or asphalt, while hardscaping can also include the use of paving stones, bricks, gravel, wood, and more. Hardscape features that involve paving are considered permanent and will increase your property taxes, while some other hardscaping features—like those involving bricks, gravel, and paving stones—will not affect property taxes. Paving also typically requires a permit, while hardscaping features considered temporary will not.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

Recycled asphalt is a durable choice for a driveway, but doesn’t have the same appearance and low maintenance as standard asphalt. For long driveways in rural communities, recycled asphalt can make a great choice. Recycled asphalt is 20% to 30% percent less expensive than standard asphalt and is better for the environment.
