Asphalt Milling vs. Asphalt Resurfacing: Which One is Right for You?
Introduction
If your pavement is showing signs of aging, you might be wondering whether asphalt milling or resurfacing is the better solution. While both methods restore damaged surfaces, they serve different purposes and come with unique benefits. Choosing the right approach can save you time, money, and unnecessary repairs down the road.
In this guide, we’ll compare asphalt milling and asphalt resurfacing, breaking down their processes, costs, and best-use cases. By the end, you'll have a clear understanding of which option best fits your paving needs.
What is Asphalt Milling?
Asphalt milling is a process that removes the top layer of an asphalt surface without disturbing the base. This method is ideal for addressing surface issues like cracks, uneven areas, and minor structural problems.
How Asphalt Milling Works
✔ A milling machine grinds the existing asphalt to a specific depth.
✔ The removed material, called Reclaimed Asphalt Pavement (RAP), is collected and often recycled.
✔ The surface is cleaned and prepared for a fresh asphalt overlay or resurfacing.
When to Choose Asphalt Milling
✅ Your pavement has surface cracks and minor wear but a solid base.
✅ You need to adjust elevation or improve drainage.
✅ You want an eco-friendly and cost-effective repair method.
What is Asphalt Resurfacing?
Asphalt resurfacing, also called overlaying, involves adding a new layer of asphalt over the existing surface. This process gives your pavement a fresh look and extends its lifespan without removing the old material.
How Asphalt Resurfacing Works
✔ A thin or thick layer of new asphalt is applied over the existing surface.
✔ The fresh layer is compacted to bond with the old asphalt.
✔ Sealing or striping may be added for extra durability and appearance.
When to Choose Asphalt Resurfacing
✅ Your pavement has multiple surface cracks but no deep structural damage.
✅ You want to extend the life of your pavement without full reconstruction.
✅ The existing asphalt is still in fair condition but needs a refresh.

FAQs About Asphalt Milling and Resurfacing
-
Yes, but milling is often recommended to ensure proper bonding and prevent future issues.
-
Milling is generally more affordable since it removes only the damaged layer, while resurfacing requires new material.
-
Resurfacing can add 10-15 years to your pavement, while milling alone is a preparatory step for resurfacing or repaving.
-
Yes, you can drive on a milled surface, but it may be rough. Resurfacing smooths it out for a better ride.
-
Freshly resurfaced asphalt typically requires 24-48 hours to cure before heavy traffic use.
Conclusion
Both asphalt milling and resurfacing play vital roles in pavement maintenance, but the right choice depends on your specific needs. If you're dealing with minor surface damage and uneven pavement, milling may be the perfect solution. If your pavement is still in good condition but looks worn, resurfacing can provide a fresh, long-lasting finish.
