Introduction

When it comes time to repave a parking lot, street, or driveway, many property owners wonder: should you simply lay new asphalt over the old surface, or is there a better approach? That’s where lot milling comes in.

Milling is the smart, cost-effective way to prepare a surface for fresh asphalt. It ensures a smooth foundation, prevents long-term problems, and even recycles old material. In this guide, we’ll explain how milling works, why it matters, and when it’s the best option.

What Is Lot Milling and Why It Matters

Lot milling is the process of removing the top layer of asphalt from a paved surface without disturbing the base layer underneath. Specialized machines grind the asphalt into small pieces that can be recycled for future paving projects.

Here’s why milling is an important step:

• Smooths Uneven Surfaces: Removes ruts, bumps, and potholes for a clean slate.
  

• Prepares for Fresh Asphalt: Creates a solid, even surface that bonds properly with new asphalt.
  

• Improves Drainage: Allows contractors to adjust slopes for better water runoff.
  

• Saves Money: Milling avoids the cost of tearing out and rebuilding the entire base.
  

• Supports Sustainability: Old asphalt is recycled, reducing waste and material costs.

Key Steps in the Lot Milling Process

To understand how milling works, here are the main steps involved:

• Assessment of the Surface: Contractors evaluate the lot’s condition to determine the right milling depth.
  

• Milling the Surface: Machines grind away the top layer, usually one to two inches, depending on damage.
  

• Adjusting Elevation and Drainage: Contractors fine-tune slopes to ensure proper water flow.
  

• Cleaning and Preparing the Base: The milled surface is swept clean and readied for new asphalt.
  

• Laying Fresh Asphalt: A new layer of asphalt is applied, creating a smooth, durable finish.

FAQs About Lot Milling

What’s the difference between milling and resurfacing?
Milling removes the old asphalt before applying new material, while resurfacing simply adds a new layer on top. Milling is more durable because it prevents issues from resurfacing over damaged layers.

Is milling necessary before paving?
Not always, but it’s highly recommended when the surface is uneven, damaged, or drainage needs improvement.

How much asphalt is removed during milling?
Typically one to two inches of the surface, but it can vary based on project needs.

Is asphalt from milling recycled?
Yes. Milled asphalt is often reused in new paving projects, making the process eco-friendly.

How long does milling take?
Most parking lot or road milling projects are completed in a few days, depending on size.

Conclusion

Lot milling is one of the smartest ways to prepare for new asphalt. It extends the lifespan of your pavement, improves drainage, and reduces costs by recycling existing materials. Whether for a commercial parking lot, municipal street, or residential driveway, milling ensures a smooth, long-lasting surface.
