Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

Yes, sealing is included to prevent staining and moisture absorption, depending on the stone type.

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.
