Best asphalt driveway pros near Winchendon, MA

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 the specific timeline for building a driveway can vary based on driveway length and local weather conditions, the average concrete driveway can require several days to lay down all of the different parts of the driveway. The curing process may require you to avoid using your driveway for a week following construction. Heavier vehicles should be kept off of a new concrete driveway for several weeks. Building a gravel driveway may take just one to two days in total.

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.

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.
