You can usually overlay an asphalt driveway after it has been paved for the first time. However, you may need to repave your driveway sooner if it shows signs of wear and tear. You can typically get 2-3 overlays before replacing your entire driveway.
Paradise Asphalt Maintenance will discuss the different methods for repairing or overlaying an asphalt driveway and when each option is most appropriate. We will also cover the costs and benefits of each technique so that you can choose the best application for your home or business driveway.
Different Ways to Repair Asphalt Driveways
Asphalt driveway repair can be done in a few different ways. The most common methods are an overlay, milling, or full-depth replacement.
1. Asphalt Overlay
An asphalt overlay is applied over the existing surface when a new asphalt layer is applied. It is often done to repair cracks or potholes. An overlay is also used to improve the appearance of an aging driveway.
Overlaying an asphalt driveway is a great way to extend its life and improve its appearance. But it’s essential to make sure that the base is strong enough to support an overlay. It means that the subgrade shouldn’t be too soft – if it is, an overlay will crack and fail again.
Milling is when the top layer of asphalt is removed to apply a new layer. This method is typically used when some large cracks or potholes cannot be repaired with an overlay.
3. Full Depth Replacement
A full-depth replacement is just as it sounds- the entire driveway will be excavated and replaced with new asphalt. It is usually only necessary if the subsurface has shifted or other serious issues. It should be a last resort as it is costly.
How Many Times Can You Overlay Your Asphalt Driveway?
So, how often can you overlay your driveway before needing a full-depth replacement? The answer is typically two to three times. After that, the subsurface will shift, and an overlay will no longer be effective. Of course, exceptions are always there to rule. If your driveway is in good condition overall, you may be able to get away with an overlay more times than that.
Paving professionals suggest that homeowners wait until their driveways show cracks or potholes before repairing them with an overlay. If caught early enough, small gaps can be filled in with sealant.
If you have a gravel driveway, you can’t put an asphalt overlay on top of it. You would need to mill or do a full-depth replacement instead. Milling involves taking out the top layer of asphalt to a specified depth before installing a new layer. It is usually done when the base is too weak for an overlay.
