Cold Patch Asphalt: How Long Will Your Repair Last and How to Extend It?

Did you know that the City of Toronto repaired more than 201,000 potholes last year? As a year-round quick fix, cold patch asphalt is a valuable tool for paving contractors and property owners throughout the GTA.

Asphalt roads and parking lots can be damaged at any time by wear and tear, spills, accidents, and environmental factors. It is important to address these issues and repair them as soon as possible to reduce the risk of personal injuries and vehicle damage.

In this article, we explore the benefits of cold patch asphalt repair and whether it’s a long-lasting solution.

Understanding Cold Patch Asphalt

Cold patch is a mixture of asphalt, selected aggregates, polymers, and other additives. The emulsion acts as a binding agent, while the aggregate provides structural integrity. This mixture allows for a flexible and durable repair material that can quickly fill potholes and cracks.

It is designed to be a short-term solution for asphalt damage, rather than a long-term solution. When comparing cold patch and hot mix asphalt, the primary difference lies in their application temperatures and durability. Hot mix asphalt is heated to around 300°F before application, providing a more permanent and durable solution. However, it requires specialized equipment and is less convenient. Cold patch asphalt, on the other hand, can be applied straight from the bag, making it a practical option for immediate repairs.

Unlike hot mix asphalt, however, which can only be applied during peak conditions, cold patch asphalt can be applied in all weather conditions and temperatures.

The Lifespan of a Cold Patch Repair

As cold patch asphalt repairs are only meant to be a temporary solution for minor asphalt damage such as potholes, the lifespan depends on a number of factors.

• Material Quality:

Using high-quality cold patch material is crucial for a durable repair. Proper storage of the material also ensures its effectiveness. Opting for a reputable brand can make a significant difference in the longevity of your repairs.

• Damage Severity:

The size and depth of the pothole or crack being repaired play a vital role in how well the cold patch holds up. Larger, deeper damages are more likely to fail sooner, so addressing these issues promptly and thoroughly is essential for extending the repair’s life.

• Traffic Volume and Weight:

Heavy traffic loads can accelerate the wear and tear of cold patch repairs. If your property experiences high traffic volumes or heavy vehicles, consider reinforcing the repair or opting for more permanent solutions like hot mix asphalt.

• Weather Conditions:

Weather is another critical factor. Moisture infiltration and extreme temperature fluctuations, such as freeze-thaw cycles, can significantly impact the repair’s longevity. Proper sealing and drainage can help mitigate these effects.

Extending the Life of Your Cold Patch

To maximize the lifespan of your cold patch repairs, proper installation and ongoing maintenance are key. Following the manufacturer’s instructions is crucial for a successful repair.

1. Preparation:

Before the cold patch asphalt is applied, the targeted area is first cleared of debris, loose asphalt and gravel, and moisture. The mixture will compact and bond better if the surface is dry.

2. Application:

Next, the cold patch asphalt is poured into the crack or hole before being compacted with the right tools. It is recommended to allow the asphalt to cure for at least 24 hours before allowing vehicles and foot traffic.

3. Sealing:

Sealcoating the surrounding asphalt can help protect the newly laid cold patch from moisture and damaging UV rays. Asphalt sealcoat products act as a protective barrier for the surface and the underlying foundation. Sealcoat should be applied once every two to three years.

4. Maintenance:

After installation, the area should be regularly inspected for cracking, pooling, or loose asphalt. Any issues or damage should be addressed promptly to prevent further damage because even the smallest of cracks can lead to deterioration if left unattended.

When to Choose Cold Patch Asphalt

Knowing when to choose cold patch asphalt as a solution can save property owners time, money, and unwanted headaches. It is important to remember that cold patch asphalt is a short-term answer for damage that requires immediate attention. It doesn’t provide a tight seal against water penetration and can’t protect pavement against wear and tear for long periods of time.

So why exactly is cold mix asphalt used if it’s not a long-term solution?

During the colder months, asphalt contractors can’t fully repair asphalt surfaces due to the weather conditions and external temperatures. So as a temporary solution—because asphalt repairs rarely happen when it’s convenient—cold patching is performed until a more permanent solution like hot mix asphalt can be used.

In addition, surfaces that are slated for replacement or resurfacing within the next year can be improved with cold patch asphalt, saving money in the long run. The costs for the material and labour are cheaper than hot asphalt mixes and cold patch repairs take less time for repairs.

Beyond Cold Patch: Permanent Repair Solutions

Most paving contractors will advise against using cold patch asphalt for large cracks or severely damaged asphalt. In certain cases, only hot mix asphalt is a safe and effective solution.

Ultimately, understanding the strengths and limitations of each repair method allows property managers to make informed decisions and ensure the longevity of their asphalt surfaces. Hiring a professional paving company for hot mix asphalt repairs is more than just an investment in good quality materials. A reputable and trustworthy contractor will have the expertise, equipment, and knowledge of proper asphalt application to ensure your repairs last for years to come.
