Get matched with top asphalt driveway pros in Grant City, MO

If your driveway is cracked, you can repave it with a process called asphalt overlay. Overlay is more cost-effective than a full replacement but is better suited for minor cracks and issues. If you have major cracks or other problems like water pooling, asphalt overlay isn’t your best bet. Plus, paving over a cracked driveway only extends the lifetime by about 10 years, whereas replacing it would start the clock over completely to give you up to 30 years.

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.

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

Chip seal layers gravel and a liquid bitumen one at a time on-site, while asphalt directly pours a pre-combined mixture. Asphalt must be sealed, but it will last up to four times as long as chip seal driveways. Aesthetically, chip seal has a natural, rustic look compared to the traditional asphalt slab.
