Get matched with top asphalt driveway pros in Milton, WI

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.

New asphalt typically needs 24 to 72 hours to dry before it can handle light foot traffic and careful driving. Although it may appear solid after a few days, the full curing process, where the asphalt reaches its peak strength, takes much longer—generally from 30 days to a year.

During this extended curing time, the surface remains relatively soft and can be damaged by heavy vehicles, sharp objects, or high temperatures. To protect your investment, it's best to avoid parking heavy machinery on the asphalt until it has fully cured.

The exact time required for drying and curing depends on several factors, including the weather, the specific asphalt mix, and its thickness. For the most accurate advice tailored to your situation, consult with your asphalt contractor.

If you’re looking for a similar, eco-friendly driveway material, you might consider one of these options:

• Permeable pavement: This material is sometimes called “pervious” or “porous” pavement; it allows stormwater to drain into the subbase, eliminating storm drain costs. 

• Gravel: Consider paving your driveway with locally sourced gravel. By sourcing from a nearby source, your money won’t fund international shipping and will be invested back into your local community.

• Natural stone pavers: Because natural stone pavers are made from organically-produced stone, there’s no new manufacturing required, limiting the environmental impact. In addition, water easily flows and drains through the gaps in the pavers.

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.
