What Is Asphalt Milling?
Asphalt milling is a process that removes some or all of the existing asphalt surface before new pavement is installed. Specialized equipment grinds away the worn layer, helping prepare the area for resurfacing.
This method can be useful when pavement has surface deterioration, uneven areas, or accumulated layers that need to be addressed. Milling can also help maintain appropriate pavement elevations around curbs, drainage areas, and entrances.
For property owners considering professional asphalt improvements, asphalt milling services can help restore the surface while addressing existing pavement conditions.
What Is an Asphalt Overlay?
An asphalt overlay involves placing a new layer of asphalt over an existing pavement surface. It can improve the appearance and usability of a driveway or parking lot without requiring complete reconstruction.
Overlays are generally best suited to pavement with a reasonably stable foundation and damage that can be addressed through resurfacing. However, significant structural problems may require additional repairs before a new layer is installed.

Asphalt Milling vs. Overlay: Key Differences
The main difference is how the existing pavement is prepared before new asphalt is placed.
- Milling: Removes the existing surface to a specified depth before resurfacing.
- Overlay: Adds a new asphalt layer over suitable existing pavement.
- Project preparation: Both methods require evaluating the pavement’s condition, drainage, and underlying support.
Neither option is automatically better. The right solution depends on the property’s current condition and project requirements.
How to Choose the Right Pavement Solution
Before deciding, consider the extent of cracking, surface irregularities, drainage concerns, and the condition of the pavement base. A professional assessment can help determine whether milling, an overlay, localized repairs, or more extensive reconstruction is appropriate.
For driveways, parking lots, and private roads, choosing the right approach can help avoid addressing surface problems without resolving their underlying causes.
