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.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

It takes recycled asphalt 48 hours to initially harden and up to 3 months to fully cure. It’s best to stay off of recycled asphalt for at least 48 hours, then you can walk or drive standard vehicles on it. Hold off on driving heavy trucks or equipment on it for at least 7 days. Allowing the surface to melt together and harden ensures that the surface stays durable and long-lasting. 

Three inches is a great thickness for a residential asphalt driveway that sees minimal to moderate traffic from cars, SUVs, and pickup trucks. However, a thicker driveway can better withstand the weight of a heavier vehicle, such as a trailer or a recreational vehicle. If you drive a heavy vehicle on a thin driveway, you risk cracking and damaging it.
