If you're a property manager, you know how crucial your asphalt parking lot is for the safety of your tenants and guests, and for maintaining building accessibility. When an asphalt surface starts to break down, it can be a hazard for both people and vehicles, and it can mar the appearance of the entire property. To stay ahead of potential problems, learn more below.

How to Tell if Your Asphalt Parking Lot Needs Repairs

1. Potholes

It's no secret that Minnesota winters can be harsh, which is why potholes are common in this area. Water from snow and rain penetrates surface cracks in the asphalt before refreezing and expanding. When warmer temperatures return, the water thaws and contracts, leaving behind a gap under the weakened surface. With time or regular vehicle use, this spot can become indented, creating a pothole that can damage vehicles and cause slips and falls.

2. Cracks

asphaltThere are many different types of cracks that can jeopardize an asphalt surface. Fatigue cracks, or alligator cracks, are interconnected lines that usually signify a deteriorating foundation. On the other hand, block cracks are large rectangular fractures that can occur in less-trafficked areas and result from shrinkage due to shifting temperatures. Finally, edge cracks appear within a foot or two of the parking lot's edge and are a sign that there isn't adequate support underneath.

3. Upheaval

Upheaval is a sharp upward disruption in an asphalt surface that's usually the result of large tree roots growing underneath. This issue may also be a byproduct of frost heaves—a phenomenon that occurs when soil under the lot swells upon freezing and pushes up the asphalt. In addition to an uneven surface, upheaval can make significant gaps and cracks or break off entire chunks of asphalt.
