5 Dreadful Signs Your Pavement Needs Mill And Overlay

You know it’s essential to keep your pavement looking good if you’re a homeowner. It makes your home look nicer, but it also helps protect the underlying surface from damage. Unfortunately, if your pavement has started showing any of the following signs, it may be time for a mill and overlay:

Alligator Cracking

If you drive a lot, you’ve probably seen alligator cracking. This type of pavement failure looks precisely like it sounds – a series of interconnected cracks that resemble the skin of an alligator. Alligator cracking is caused by weak base materials, excessive stress, and poor drainage. While alligator cracking is unsightly, it indicates that your pavement requires mill and overlay.


Potholes form when water seeps into cracks in the pavement & then freezes, expands, and thaws, causing the cracks to widen and deepen. Over time, the weight of traffic passing over these weak spots causes the pavement to collapse, forming a pothole. Potholes damage vehicles and injure drivers and passengers, but they are also costly to repair. The best way to fix a pothole is to mill out the damaged section of pavement and then overlay it with new asphalt. This process requires specialized equipment and trained operator, so it’s best to leave it to the professionals.


Raveling is when the surface of your pavement deteriorates, and the aggregate starts to loosen, creating a dangerous driving hazard. Over time, raveling can lead to potholes and other severe damage to your pavement. If you notice raveling, it is important to have your pavement checked by a professional as soon as possible. If left untreated, raveling can cause extensive damage to your pavement and may even require complete replacement.


Over time, asphalt pavement will develop ruts, or depressions, on the surface. These ruts can be caused by various factors, including weathering, vehicle traffic, and improper installation. Rutting can also be exacerbated by poor drainage. If left unaddressed, rutting can damage the pavement’s surface and underlying structure. Asphalt is much more susceptible to rutting. This is because asphalt is a flexible material that compresses under load. The best way to repair rutting is to mill out the affected area and install an overlay.

Edge Deterioration

Edge deterioration happens when the edge of the pavement is not as well protected from the elements as the rest of the pavement. As a result, it is subject to more wear and tear. If left unchecked, this can eventually lead to cracks, potholes, and other problems. One way to prevent this is to have your pavement milled and overlaid.

If your pavement is starting to show any of these signs, it’s time to think about mill and overlay. Mill and overlay involve milling and removing the top layer of asphalt and replacing it with a new layer. This can help improve the overall appearance of your pavement and extend its lifespan. However, if you wait too long to do this, you may need to replace your entire pavement, which is much more costly.
