Understanding Asphalt Sealcoating

Asphalt is one of the most reliable paving materials out there. It’s durable, cost-effective, and aesthetically pleasing. However, as time goes by, your asphalt pavement may show signs of wear and tear, like cracks, potholes, and discolorations. That’s where sealcoating comes into the picture. In this blog post, we’ll take a closer look at what asphalt sealcoating is, how it works, and why it’s crucial for the overall health and longevity of your asphalt pavement.

What is asphalt sealcoating?

In layman’s terms, asphalt sealcoating is a protective coating applied to the surface of asphalt pavement to shield it from the damaging effects of natural elements, such as moisture, sunlight, and chemicals. Sealcoating enhances the pavement’s appearance, prevents water from seeping through the surface and into the underlying base layer, and protects the pavement from oil and gasoline spills, oxidation, and other types of wear and tear.

How does asphalt sealcoating work?

The sealcoating process involves several steps, including cleaning the pavement surface, repairing any cracks or potholes, and applying the sealcoat material using spray equipment or handheld tools. The sealcoat material is typically a coal tar or asphalt-based emulsion that contains additives, such as sand, latex, and polymers, to improve durability, adhesion, and water resistance.

Why is sealcoating important for asphalt pavement?

Sealcoating offers several benefits for asphalt pavement owners and managers, including:

Cost-effective:

Sealcoating helps extend the life of your asphalt pavement by protecting it from premature wear and tear, thus reducing the frequency and cost of repairs or replacement.

Aesthetic appeal:

A freshly sealcoated parking lot or driveway looks great and can enhance your property’s curb appeal and overall value.

Safety:

Sealcoating helps fill in small cracks and gaps, making your pavement smooth and level, which can reduce the risk of accidents and injuries caused by tripping or falling.

Sustainability:

Sealcoating can help reduce your environmental impact by preventing pollutants from seeping into the soil and water systems.

When should you sealcoat your asphalt pavement?

The frequency of sealcoating largely depends on factors such as climate, traffic volume, and pavement age. In general, you should plan to sealcoat your asphalt pavement every few years or when the surface starts to show signs of fading, cracking, or staining. Keep in mind that sealcoating should only be done on a clean, dry surface and during fair weather.

Sealcoating is a simple yet effective way to protect and enhance your asphalt pavement. By investing in regular sealcoating, you can save money on repairs, increase your property’s value, and ensure the safety and sustainability of your pavement for years to come.
