Get matched with top asphalt driveway pros in Chehalis, WA

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.

You can expect your asphalt pavement to last anywhere from 20 to 30 years, or 25 years on average. The life expectancy of your asphalt driveway depends on the climate, the amount of traffic, and how well you maintain it. While you can’t necessarily control some of these factors, you can control the amount of maintenance effort you put into your driveway. 

To prevent your asphalt from deteriorating prematurely, you should follow a good maintenance routine involving regular cleaning, reparation work, and resealing.

When comparing installation costs, asphalt is often less expensive upfront than concrete. Asphalt prices typically range from $7 to $15 per square foot, while concrete can range from $3 to $18 per square foot. However, long-term costs should also be considered. Concrete driveways generally last longer (up to twice as long) and require less maintenance, which can make them more affordable over their lifespan. While asphalt has a lower installation cost and is easier to repair, it requires more frequent maintenance, such as sealing, which can add up over time. Therefore, while concrete is more expensive initially, its durability may offset the cost in the long run.
