This curb is the raised portion of the driveway that differentiates the driveway from the main road surface. These curbs should be built with a ramp design to allow the automobile to easily move from the road area into the main driveway.

The layer of asphalt in a driveway should be around 2 to 3 inches thick.

Many driveways include landscaping that outlines the perimeter of the driveway. This area is typically outlined with gravel, mulch, or logs. When designing a driveway landscape, it's important to consider how the driveway's curb will be affected by the surrounding material.

Some older homes may not include driveway curbs. This is typically because the driveway was added to the home after it was originally built.

These agencies will ensure the new curb meets the specification required by the local government.
