Best driveway sealcoating pros near Townsend, MT

Asphalt driveways last anywhere from 15 to 30 years, but if you don’t stay on top of repairs, you may find yourself spending extra to replace your driveway before its typical lifespan. Stay on top of repairing cracks and potholes by routinely inspecting your driveway once or twice a year. It’s a good idea to pressure wash your asphalt driveway at least once a year to keep it clean. Apply a sealer every one to five years, based on your climate.

Asphalt is made of aggregate materials (sand, rocks, and gravel) and bitumen, a viscous, petroleum-based, waterproof substance. These materials are mixed together at extremely high temperatures to form asphalt.

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, it’s possible to seal your driveway too much. Whether you have an asphalt or concrete driveway, sealing it every year opens your driveway to potential damage. Sealing an asphalt driveway annually may cause the seal to crack and peel even more. It may even trap oils within the asphalt that can leave you driving on a soft driveway. Avoid sealing your concrete driveway too much to prevent the concrete from cracking. If water enters these cracks, it can freeze, expand, and cause the cracks to worsen.
