Why So Many Potholes In Michigan?

The Truth About Potholes In Michigan

Potholes in Michigan are somewhat unavoidable because of our fluctuating temperatures and brutal winters. However, potholes can be managed through proper initial construction and routine maintenance.

How Do Potholes Form?

Potholes occur when the pavement or sub-base beneath the asphalt cannot support the weight of traffic. This is true whether the pavement is an asphalt parking lot or an asphalt roadway. Although weight and traffic flow play a role in creating a pothole, the main culprit is moisture. Any time there are cracks in the surface, water has access to the sub-base. Moisture allowed to penetrate the surface layer of asphalt will weaken the sub-base and cause significant damage.

When temperatures drop, the sub-base expands when the moisture freezes, pushing the pavement to the surface. When the temperature rises the sub-base thaws and contracts.

After enough freeze-thaw cycles occur a gap is created between the asphalt pavement and the sub-base. Constant traffic flow will crack the surface and eventually break the pavement, creating a pothole. The longer a pothole is left untreated, the more extensive and expensive the damage will be. It is cost-effective to repair potholes as soon as they occur.
