When asphalt pavement starts to look damaged, property owners usually have two options: milling or resurfacing. The two methods may sound the same, but they are different in how they work, how much they cost, and what they achieve. It’s important to know the difference between asphalt milling and resurfacing so you can choose the best option for your property.
What is the process of asphalt milling?
When you mill asphalt, you use a special machine to take off the top layer of asphalt while leaving the sub-base in place. After that, the surface is ready for a new layer of asphalt. This method is great for fixing problems on the surface while keeping the strong base underneath.
What does it mean to resurface asphalt?
Adding a new layer of asphalt on top of the old pavement without taking any of it away is called resurfacing, which is also known as overlaying. It gives a new surface, but it doesn’t fix problems with drainage or other underlying issues.
Milling and resurfacing are different in important ways.
1. Price and how long it lasts
• Milling costs a little more up front because it takes more steps, like grinding and recycling the asphalt. But it usually gives results that last longer.
• Resurfacing costs less in the short term, but it may need more repairs more often because it doesn’t fix underlying problems.
2. Getting the surface ready
• Milling makes sure the surface is flat, smooth, and ready for the new asphalt layer to stick well.
• Resurfacing just covers up the old surface, which can cause layers to be uneven or cracks to come back.
3. Structural Strength
• Milling keeps the base strong while taking away damaged material.
• Resurfacing only covers up problems on the surface and may not work if the pavement has deeper structural issues.
4. Concerns about drainage
• Contractors can change the slope and grade of the land with milling to improve drainage.
• Resurfacing doesn’t fix drainage problems, which can lead to water pooling and more damage in the future.
When to Use Milling
• If your pavement has a lot of cracks, potholes, or uneven grades.
• If you want a solution that will last a long time.
• If there are problems with drainage that need to be fixed.
When to Pick Resurfacing
• If the surface of your pavement is worn but the underlying structure is fine.
• If you need a quick fix that doesn’t cost much.
• If you don’t need to change the grade or fix the drainage.
Why it’s important to get professional help
It depends on how bad your pavement is whether you should mill it or resurface it. An experienced contractor can look at your property and suggest the best option for the long term.
In conclusion
Both resurfacing and milling can make asphalt surfaces look and work better, but they are not the same thing. Resurfacing is a quick fix that makes things look better, but milling is a longer-lasting and more complete solution. Professional asphalt milling services are often the best investment for property owners who want results that last.
