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.

A properly applied asphalt driveway sealer, or sealcoat, should last between one and five years. The industry standard is to reseal every two to three years for optimal protection. If you live in a climate with extreme weather, such as heavy rainfall or freezing temperatures, you may need to reseal your driveway more frequently, around every two years. Signs that your driveway needs a new coat of sealant include the appearance of small cracks or uneven drying after rain.

Most sealing projects take 1-2 days, including drying time before allowing traffic.

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.
