Asphalt Milling 101: Your Guide to Asphalt

Asphalt is one of the most affordable and adaptable materials when it comes to paving options. We use it in road construction, parking lot paving, and more. To repair an asphalt parking lot, we utilize asphalt milling.

Does Your Parking Lot Require Asphalt Milling?

Asphalt milling does more than repair superficial cracks and potholes. If you have potholes in your asphalt, you most likely have deeper structural issues. If you do not handle the situation quickly, it can develop into a structural issue in minor cases.

When contractors remove the first layer of asphalt, they can investigate deeper issues. Some damages that require asphalt milling include crumbling or cracking asphalt. When you have cracks, water erosion is more likely. Other damages may include shoving, rutting, gradient defects, and uneven pavement. When you ignore defects with your commercial parking lot, guests are more likely to suffer injuries or vehicle damages.

What Are the Different Types of Asphalt Milling?

When it comes to asphalt milling, we will determine the type to use based on the damage done to your parking lot.

There are various types of asphalt milling, including:

  • Micro-milling
  • Planing
  • Fine-milling

Micro-milling, for example, treats most surface defects, whereas planing is a more complex process for roadways and large properties. Micro-milling only takes a thin layer of asphalt from the top. On the other hand, planing takes the damaged pavement from the top and uses it to create new aggregate for the surface.

When a contractor uses fine-milling, it is for foundational defects. The contractor extracts the damaged surface asphalt and repairs the defects before overlaying the new sealant. The purpose is to restore faults and make the asphalt look new again. The milling process takes about 24 to 48 hours to complete.
