When asphalt pavement begins to show signs of damage, property owners are usually presented with two common solutions: milling or resurfacing. While the two methods may sound similar, they differ in process, cost, and outcomes. Understanding the difference between asphalt milling services and resurfacing helps you make the best decision for your property.
What Is Asphalt Milling?
Asphalt milling involves removing the top layer of asphalt with a specialized machine, leaving the sub-base intact. The surface is then prepared for a new asphalt overlay. This method is ideal for addressing surface-level issues while preserving the strong foundation underneath.
What Is Asphalt Resurfacing?
Resurfacing, sometimes referred to as overlaying, involves adding a new layer of asphalt on top of the existing pavement without removing any part of it. While it provides a fresh surface, it doesn’t correct underlying issues or drainage problems.
Key Differences Between Milling and Resurfacing
1. Cost and Longevity

• Milling is slightly more expensive upfront because it involves additional steps, such as grinding and recycling the asphalt. However, it typically delivers longer-lasting results.
• Resurfacing is cheaper in the short term, but since it doesn’t address underlying problems, it may require more frequent repairs.

2. Surface Preparation

• Milling ensures the surface is even, smooth, and ready for a strong bond with the new asphalt layer.
• Resurfacing simply covers up the old surface, which can lead to uneven layers or persistent cracks reappearing.

3. Structural Integrity

• Milling maintains the strength of the base while removing damaged material.
• Resurfacing only hides surface issues and may not be effective if the pavement has deeper structural problems.

4. Drainage Concerns

• Milling allows contractors to adjust slope and grade for better drainage.
• Resurfacing doesn’t correct drainage issues, which can cause pooling water and future damage.

When to Choose Milling

• If your pavement has extensive cracks, potholes, or uneven grades.
• If you want a long-term, durable solution.
• If drainage problems need to be addressed.

When to Choose Resurfacing

• If your pavement has minor surface wear without underlying damage.
• If you need a quick, budget-friendly fix.
• If you don’t require grade adjustments or drainage improvements.

Why Professional Guidance Matters
The choice between milling and resurfacing depends on the condition of your pavement. An experienced contractor can inspect your property and recommend the best option for long-term results.
Conclusion
Both milling and resurfacing can improve the appearance and function of asphalt surfaces, but they’re not interchangeable. Milling provides a more durable and comprehensive solution, while resurfacing offers a quick cosmetic fix. For property owners who want lasting results, professional asphalt milling services are often the best investment.
