If your asphalt driveway is starting to show its age—cracking, crumbling, or becoming uneven—you may be considering your options. Two of the most common solutions are driveway milling and complete driveway replacement. While both methods aim to restore your driveway’s function and appearance, they differ significantly in process, cost, and long-term results.
At Unlimited Underground, we help homeowners and property managers choose the right approach based on their driveway’s condition, budget, and goals. Here’s a breakdown of the key differences between driveway milling and full replacement to help you make an informed decision.
What Is Driveway Milling?
Driveway milling (also known as asphalt milling) is a cost-effective resurfacing process that involves removing the top layer of damaged asphalt, usually around 1–3 inches deep. Once this layer is removed, the surface is cleaned and prepped for a fresh layer of asphalt, which is then installed and compacted to create a smooth, new finish.
Benefits of Driveway Milling:
- More affordable than full replacement
- Faster installation and less downtime
- Reuses the existing base, which can be environmentally friendly
- Great for driveways with surface-level issues like minor cracks, fading, or uneven patches
However, milling is only suitable if the underlying base of the driveway is still structurally sound. If the damage runs deeper, resurfacing alone may not solve the problem.
What Is Full Driveway Replacement?
Full replacement involves completely removing the existing asphalt surface and base materials and then rebuilding the driveway from the ground up. This includes laying a new sub-base, compacting it, and installing a fresh layer of asphalt to create a strong, stable foundation and smooth surface.
Benefits of Full Replacement:
- Addresses deeper structural issues, such as base failure, erosion, or drainage problems
- Provides a longer-lasting solution, often with a lifespan of 20+ years when properly maintained
- Allows for regrading or redesigning the driveway for improved slope, drainage, or aesthetics
- Ideal for severely damaged or uneven surfaces
Although it’s more expensive and time-consuming than milling, full replacement is often the best choice when the driveway has significant deterioration or drainage concerns.
How to Choose the Right Option
The best solution depends on the extent of the damage and the condition of the underlying base. Here are a few general guidelines:
- Choose milling if your driveway has superficial wear and tear, minor cracks, or unevenness but the foundation is still stable.
- Choose full replacement if your driveway has deep cracks, potholes, standing water issues, or an unstable base that can’t support new asphalt.
A professional inspection can determine whether your base is salvageable or if it’s time for a complete rebuild.
