What is Asphalt Sealing?
Asphalt sealing is the process of applying a protective layer to asphalt pavements, roads, parking lots or driveways, with the intent of prolonging its lifespan. It is primarily done by applying an asphalt emulsion or coal tar pitch emulsion to the existing asphalt surface. This technique makes the surface more resistant to water, oil, UV rays, and other harmful substances that can damage the pavement.
Asphalt sealing is a cost-effective method that helps preserve the surface of the pavement and prevent small cracks from becoming larger, more expensive repairs. Over time, paved surfaces are exposed to elements and can become brittle and crack, which leads to structural damage and potholes. This makes pavement less safe for drivers, walkers, and bikers alike.
Benefits of Asphalt Sealing
1. Improved Appearance – Sealing enhances the look of asphalt surfaces and makes them more appealing to visitors. This is particularly important for commercial parking lots, where first impressions are crucial to attracting new customers.
2. Protection from Freezing and Thawing – Changes in temperature, especially during winter, causes expansion and contraction of materials. This can result in cracking or lifting of the pavement. Asphalt sealing can prevent this damage by creating a protective layer on the surface of the pavement.
3. Protection from UV Rays – Sealing provides protection from UV rays which can cause oxidation and damage the asphalt binder. By sealing, asphalt surfaces are better able to handle exposure to UV light and increased temperature from sunlight.
4. Prevents water damage – Water is the pavement’s worst enemy. It can seep into cracks and cause the base layer to deteriorate. This will result in bigger cracks or even potholes. Sealing can prevent water damage by stopping water from entering underneath the surface of the pavement.
When to Seal Asphalt Pavement
The best time to seal pavement is when it is new or when the surface is in good condition. Sealing should also be done once every two or three years on average, or as recommended by pavement professionals. This increases its lifespan and will prevent costly repairs in the long run.
There are some signs to look out for when considering whether to seal pavement. These include faded color, small cracks, and erosion. If you do see any of these issues, then it’s time to consider sealing.
The Process of Asphalt Sealing
The process of asphalt sealing requires special tools and equipment, including a sealcoat sprayer, squeegee or broom, and asphalt sealant.
The first step is to clean and sweep the area to be sealed. All debris must be removed from the surface to ensure proper bonding. Oil spots should be treated with a degreaser to ensure that the sealant adheres, and any cracks filled with a patching compound.
The next step is the application of the sealant, which is either an asphalt emulsion or coal tar pitch emulsion. Sealcoats are usually applied in two or three thin coats to ensure the best results. A sealcoat sprayer is used for larger projects, while a squeegee or broom is used on smaller projects.
The final step is to let the sealcoat dry completely, usually requiring 24-48 hours.
Conclusion
Asphalt sealing is a cost-effective solution to prolong the lifespan of pavement. By creating a protective layer that prevents water damage, UV rays, freezing and thawing, and general wear and tear, you can save money by avoiding costly repairs.
