Driveway aprons typically range between four and seven inches thick, though your town's building codes will likely have specific requirements. Additionally, you may need to add a layer of permeable aggregate in the excavation below your paved apron to ensure proper stormwater drainage.

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.

You should not attempt to install your own driveway. Whether working with asphalt or pavement, this is a complicated project that requires special equipment. Talk to some nearby asphalt or paving professionals and discuss your particular needs—it’s a good idea to get a few quotes and look at the company’s past work.

The cost to pour a driveway apron depends on the material and size. Concrete costs $3 to $10 per square foot, asphalt ranges from $2 to $5, and pavers are $5 to $15 per square foot. Additional expenses, like excavation, base material, and labor, can increase the total cost. For example, a standard 12x15-foot concrete apron could cost between $540 and $1,800, depending on local rates and additional work required. Always consult a local driveway paving contractor to get an accurate estimate tailored to your project.
