How Do Potholes Form And What Causes Them?

We’ve all been there—you’re driving to work, coffee in hand, when all of a sudden, thump! Your vehicle takes a dip into an unseen pothole, rattling your car, spilling your coffee, and ruining your morning.

For commercial property owners, these pavement annoyances are more than just eyesores; they’re a serious safety concern that can damage your business operations, vehicles, and your bottom line.

But what exactly causes these troublesome craters to appear (seemingly overnight)? Let’s take a look into the interesting, yet often frustrating, world of pothole formation.

So, What Are Potholes?

Potholes are like dental cavities, but for pavement and are most common in asphalt surfacing. They don’t just happen overnight; they develop gradually over time. While it may feel like these pesky craters appeared out of nowhere, they’ve actually been weeks or months in the making. Over time, the asphalt cracks and is broken away under repeated traffic passing over, forming a hole with rough vertical sides. Just like dental problems, the earlier you catch and fix them, the better the outcome.

What Causes Potholes? 4 Factors Contributing to Pothole Formation

These irritating pavement problems aren’t caused by a single culprit but rather by a group of factors working together to break away your parking lot or paved surface. The initial asphalt cracks may seem harmless but are actually the first step in pothole formation.  Understanding these factors will help business owners understand how to prevent potholes and maintain the structural integrity of commercial pavement.

1. Weather Conditions

Extreme weather conditions can be particularly harsh on pavement, especially during the winter months. When a tiny crack in your parking lot fills with rainwater or snow and temperatures plummet below freezing, the water turns into ice and expands, much like a forgotten soda exploding in the back of the freezer. As temperatures warm up, the ice melts, leaving behind a slightly larger space than before. This freeze-thaw cycle then repeats itself over and over again, gradually weakening the pavement from within.

2. Inadequate Drainage Systems

When water can’t escape the pavement’s surface, it becomes the perfect spot for accumulation. Your pavement shouldn’t act like a sponge, but without proper drainage systems, that’s exactly what happens. The trapped standing water weakens the foundation beneath your pavement, creating the perfect conditions for pothole formation.

3. Traffic Load and Frequency

Every vehicle that passes over your pavement contributes to pothole formation. While one car won’t cause damage, repeated impacts of heavy trucks and frequent traffic create a constant flexing motion in the pavement, like taking a credit card and bending it back and forth until it eventually weakens. Areas that experience continuous traffic, like entranceways or loading zones, are particularly vulnerable to this repeated stress.

4. Quality of Pavement Materials

Using low-quality materials in pavement construction significantly drops its durability and resistance to pothole formation so it won’t stand the test of time. This leaves your pavement more prone to cracking, potholes, and degradation, especially in areas with high traffic and extreme weather. Premium materials create a more resilient surface that can better withstand the daily assault of weather, traffic, and time.

Solutions to Prevent Potholes From Occurring

Thankfully, you’re not helpless against pothole formation. Proactive pavement maintenance can help keep your surfaces smooth and problem-free. Here’s your action plan for pothole prevention and making sure your pavement is built to last.

Regular Maintenance & Inspection Routines

Regular maintenance and inspections are crucial for early problem detection. Creating a consistent schedule allows you to identify and address minor issues before they turn into major problems. Look for signs of cracking, water pooling, or surface deterioration that could indicate a potential pothole formation beneath the surface.

Install Proper Drainage Systems

Effective water management is important in preventing pothole formation. A properly designed and maintained drainage system helps to direct water away from paved surfaces, reducing the risk of water seeping in and the potential damage it will cause. Regular cleaning and maintenance also ensure these systems continue to function properly throughout the year.

Utilize Premium Materials

Investing in quality materials is another vital factor in the performance and longevity of your pavement. Though they may cost more initially, it pays dividends in the long run. They are less likely to form cracks that lead to potholes due to the usage of modern materials like polymer-modified asphalt. Premium materials are also better equipped to withstand environmental stresses and heavy traffic loads, extending the lifespan of your pavement.

Regularly Clean Your Paved Surfaces

Maintaining clean pavement surfaces is a simple yet effective preventative measure. Regular cleaning removes debris and contaminants that can trap moisture under the pavement’s surface. This practice helps to prevent water retention and reduces the risk of the surface deteriorating, which can lead to pothole formation.

Arrange Timely Repairs

When damage does occur, quick action is essential. Addressing small problems through pothole repair, seal coating, and maintenance can prevent them from developing into a costly, headache-inducing nightmare. This proactive approach helps maintain the integrity of your pavement and extend its lifespan.
