Asphalt paving is a popular choice for both residential driveways and commercial parking lots due to its durability, cost-effectiveness, and aesthetic appeal. However, to ensure longevity and maintain the integrity of the asphalt surface, proper drainage and regular sealing are crucial aspects of asphalt maintenance.
Proper drainage is essential to maintain the integrity and durability of your asphalt surface. If water can't drain off properly, it can cause various issues:
- Potholes and Cracks: When water accumulates on the asphalt surface and penetrates through cracks, it can erode the base layers, leading to the formation of potholes and further deterioration of the asphalt.
- Freezing and Thawing: In colder climates, trapped water can freeze and expand, causing cracks to widen. The subsequent thawing allows even more water to seep in, creating a vicious cycle of damage.
- Water Damage: Over time, standing water can soften the asphalt binder, causing the surface to become weak and degrade.
To avoid these issues, consider the following:
- Grading: The asphalt surface should be properly graded to encourage water runoff. The surface should be sloped away from any buildings or structures and toward appropriate drainage points.
- Drainage Systems: In larger asphalt installations, such as parking lots, consider installing drainage systems like catch basins or trench drains to facilitate water management.
- Regular Maintenance: Regular inspections and maintenance are necessary to ensure that drainage systems remain unblocked and functional.
The Role of Sealing in Asphalt Maintenance
Sealcoating is another critical aspect of asphalt maintenance. It involves applying a protective layer to the asphalt surface to protect it from elements that could cause damage.
Here's why sealing is essential:
- Protection Against Weather Damage: Sealcoating protects the asphalt surface from the sun's UV rays, which can cause the asphalt to become dry and brittle. It also provides a waterproof layer that prevents water from seeping into the asphalt.
- Resistance Against Spills: Asphalt is a petroleum product, and spills of oil or gasoline can dissolve the asphalt binder, leading to surface damage. Sealcoating provides a protective layer that resists such spills.
- Enhanced Appearance: Sealcoating gives the asphalt surface a sleek, dark finish that can enhance the curb appeal of your property.
When sealing your asphalt surface:
- Wait for the Right Time: Newly installed asphalt should cure for several months before sealcoating. Also, sealcoating should be done in warmer weather, as the sealant needs to cure.
- Clean the Surface: Before sealcoating, clean the asphalt surface thoroughly to remove any debris or oils that may prevent the sealant from adhering properly.
- Apply Regularly: Sealcoating is not a one-time task. Depending on the traffic and weather conditions, your asphalt surface may need sealcoating periodically.
