Get matched with top asphalt driveway pros in Brunswick, TN

In the United States, roads are usually categorized as one of three types: public roads, other drivable roads, and non-drivable roads. These categories dictate how a road can be used; a non-drivable road might be classified that way because it is heavily damaged and unsafe for cars.

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

Several materials are suitable for steep driveways. Gravel and crushed stone are affordable options that provide good traction. Permeable pavers—such as plastic, rubber, or concrete—filled with gravel or crushed stones are also excellent, as they allow water to drain without causing erosion and perform well in ice and snow. Another option is resin, which can be coated with an anti-slip finish and helps prevent puddles. For added stability, you can install a retaining wall to prevent pavers and gravel from shifting over time.

The choice between asphalt and concrete depends on your priorities, budget, and climate.

Concrete is generally more durable, lasting up to 50 years with minimal upkeep, and offers more customization options like staining and stamping, which can add more to a home's value. However, it is more expensive upfront and can be prone to cracking in cold climates where water can freeze and expand.

Asphalt is typically cheaper and quicker to install and is easier to repair. It performs better in colder climates. However, it requires more maintenance, including regular resealing, has a shorter lifespan, and can get hot and sticky in intense sunlight.

Ultimately, if durability and long-term value are key, concrete is often the better choice. If upfront cost and performance in cold weather are more important, asphalt may be preferable.
