Get matched with top asphalt driveway pros in Mount Carmel, TN

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

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 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.

Gravel is the most economical and least expensive driveway material, costing between $1 and $3 per square foot. This is significantly cheaper than alternatives like asphalt or concrete. However, it's important to consider long-term costs, as gravel driveways require regular maintenance. You will likely need to add new gravel filling once or twice a year and regularly rake it to keep it level, which can add to the overall cost over time.
