A driveway's lifespan varies by material. Asphalt driveways typically last 15 to 30 years, while concrete driveways last longer, between 20 and 50 years. The longevity of any driveway is affected by factors like extreme temperatures, heavy traffic, and the quality of maintenance. Regular upkeep, such as filling cracks, resealing the surface, and ensuring proper drainage, can help extend its life. For gravel driveways, regrading to fill in uneven areas every year or two is recommended.

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.

Yes, you can put thin pavers over a concrete driveway. However, it's always best to talk to a driveway installer before starting. You'll need to ensure that the concrete below is in good enough shape to hold the pavers and that the driveway will still meet local building codes.

The ideal distance between stepping stones depends on your design preference. A general rule is to place them about 24 inches apart from center to center to match an average person's stride. Another common approach is to leave about 6 inches of space between the edges of each stone; this can be adjusted to fit the path's total length without cutting pavers. If you plan to plant between the stones, leave at least 6 to 8 inches of space to give the plants room to grow.
