Potholes are depressions or holes in a road surface caused by the wear and tear of traffic and weather conditions. These imperfections often begin as small cracks but grow larger over time due to continued stress and neglect. Potholes can range in size from minor dips to large craters, depending on how long they’ve been left unrepaired.

What Is a Cold Pothole Patch?

Cold patching is a quick and inexpensive method often used for temporary repairs. It involves filling the pothole with a pre-mixed asphalt compound that doesn’t require heating. After placing the material in the hole, it’s compacted to create a level surface.

How To Fix A Pothole The Right Way

Q: Why Are Potholes Dangerous?

Potholes pose a significant risk to both vehicles and pedestrians. Drivers who hit potholes can experience tire damage, misaligned wheels, or even suspension issues. For motorcyclists and bicyclists, a pothole can lead to loss of control and serious accidents. Pedestrians are also at risk of tripping and falling, especially if the pothole is located on a poorly lit roadway or sidewalk

Potholes are a nuisance to both motorists and pedestrians. They pose a safety hazard for many while making the area less attractive. So, when you’re faced with a pothole that can cause costly damage and injury, patching it up right away is a must.

What are Potholes?

Essentially, potholes are broken parts of the road’s surface layer. When the said layer, which is usually made of asphalt, cracks and is broken away by water damage or stress from traffic passing over it, it usually forms depressions or holes.

Potholes can start small but can easily expand and deepen if not addressed properly. Additionally, while this type of road damage is usually seen on asphalt roads, it can still happen on all other road types.

How Do Potholes Form?

Several factors contribute to the formation of potholes, making it complex. It has several stages to it.

Potholes usually start when there’s a crack in the road. This is usually caused by fatigue from passing traffic, especially when the material used is sub-park, making it lack the strength needed to withstand pressure.

Other factors may also contribute to cracking, including bad water drainage, old asphalt, thermal movements in the soil that cause shrinkage cracks, and utility works.

The second stage is when water seeps down these crafts. This wets the layer of material underneath, causing it to weaken. Water also softens the soil under the road, causing movement and aggravating the cracks.

Moving traffic then worsens the damage on the pavement. This causes the craft to become a pothole as the damage grows bigger and deeper. On top of this, the moisture exacerbates it as water expands and contracts depending on the weather.

Why are Potholes Dangerous?

Potholes are one of the biggest safety hazards on the road in several ways. While they look innocuous, they pose a larger threat to motorists and pedestrians alike.

For one, potholes can cause severe damage to a vehicle. It can blow out tires, misalign them, and damage car suspensions.

A bigger problem is that it can cause accidents and injuries to drivers and pedestrians. If you run over a pothole in a vehicle, you may lose control of it. It’s even more dangerous for motorcyclists and cyclists as they can be thrown off the vehicle if they run over a pothole.

Different Pothole Repair Methods

There are many different pothole patching techniques professionals use. Each has pros and cons, depending on how large the holes are and how severe the damage is. Here are some of the most common ones:

Cold Pothole Patch

Cold patching is likely the fastest and most inexpensive way to fix a pothole. It involves pouring in a pre-mixed asphalt material that doesn’t need heat to cure.

Pros: Easy to apply, no need for special equipment, best used in emergencies
Cons: Not a good fix for long term, prone to breaking in heavy traffic areas

How to Apply a Cold Patch:

The first step is cleaning the exposed surface thoroughly. Make sure to remove any loose debris and water.
Once it’s clean, pour the cold patching compound into the pothole. Make sure to overfill it slightly.
Using a tamper or shovel, pressure the compound tightly and compress the material into the hole.
Make sure the patch is level with the surrounding road.

Infrared Patching

Another way to cover a pothole is by infrared patching. This method uses infrared technology to heat the damaged asphalt and surrounding area. Doing this makes it malleable and easy to shape. New asphalt is blended with the heated material and compacted to provide seamless repair.

Pros: Durable, cost-effective for medium-sized repairs, creates a smooth finish.

Cons: Will need special equipment and trained personnel to operate the equipment

How to Do Infrared Patching:

After cleaning the hole, position the infrared heater over it. Then, turn it on to soften the existing asphalt.
If softening the material exposes loose or damaged material, make sure to rake it and remove it from the hole.
Then, add the new asphalt and mix it with the heated surface.
Once the new asphalt is mixed in, compact the area using a roller or plate compactor.
Finally, let the patch cool and harden before opening it to traffic.

Mill Patching

As its name suggests, this method involves milling. In particular, you must mill out the damage until it reaches a specific depth. You will add the new asphalt to this.

Pros: Very durable, best used for large potholes and areas with high-traffic
Cons: Time-consuming, uses a lot of resources and heavy equipment, and is expensive.

Steps for Mill Patching:

The first step in this method is removing some of the asphalt on the pothole using a milling machine.
After milling, the exposed area will need to be cleaned so that the fresh asphalt will stick properly.
Then, apply a tack coat to the exposed surface.
Fill in the exposed area with fresh asphalt.
Finally, the new asphalt will need to be compacted using a roller until it is level with the other road parts.

Digout Patching

When doing dugout patching for potholes, you will need to excavate the pothole area and a part of the surrounding road.

Pros: Extremely durable, best used for severe and recurring potholes
Cons: Labour-intensive and expensive

Steps for Digout Patching:

The first step for this method is digging out the pothole and its surrounding areas until you reach the base.
Then, you must remove all the debris and check if the base needs repairs or replacement.
If necessary, repair or replace the base layer.
After this, you should add fresh asphalt and compact it in layers.
Make sure to smoothen and level the surface for a seamless look.

Things to Avoid When Repairing Potholes

If you want to fix potholes correctly, you must avoid common mistakes that compromise the quality. Here are some of them:

Not Preparing the Surface: If you don’t thoroughly clean the exposed part of the pothole, you can lower the quality of your fix. It may prevent the repair material from bonding correctly to the exposed surface.
Using Low-Quality Materials: Using cheap materials will lower your expenses for the short term but will cost more in the long run as you will need more frequent repairs.
Rushing the Process: For a durable and long-lasting fix, you should compact the new material properly and let it cure for the right amount of time.

Challenges of Repairing Potholes

Repairing potholes comes with its own set of challenges. Here are some that you may encounter:

Weather Dependence: Many of the pothole repair methods will have to be done in cold and warm weather. This can cause delays in repairs, especially during cold months.
Budget Constraints: You must invest in high-quality materials to ensure your fixes are long-lasting and durable. However, this can be pretty expensive, so places without a lot of funds may find it challenging to do proper repairs.
Traffic Disruption: Repairing potholes on busy roads often requires lane closures or detours. This will prove to be an inconvenience to many drivers.

Making the Right Repairs

Fixing a pothole correctly requires understanding what caused it and choosing the proper method, depending on the case. Investing time and resources in proper techniques will ensure safer, longer-lasting results. By addressing potholes as soon as possible, you can protect vehicles, pedestrians, and the integrity of the road itself.
