Best Asphalt Maintenance Tips: How to Extend the Life of Your Pavement

Feb 26

Asphalt paving is a durable and cost-effective choice for driveways, parking lots, and roads. However, like any surface, it requires regular maintenance to stay in good condition and maximize its lifespan. Proper care can prevent costly repairs and keep your asphalt looking smooth and new for years to come. This article provides the best asphalt maintenance tips, helping you protect your investment and extend the life of your pavement.

1. Regular Cleaning

Keeping your asphalt surface clean is one of the simplest yet most effective maintenance tasks. Dirt, debris, and stains can weaken the surface over time and lead to deterioration.

Sweep Regularly: Remove leaves, dirt, and debris to prevent them from accumulating and trapping moisture.
Remove Stains: Clean oil, grease, and other spills as soon as possible. Use a degreaser or a mixture of dish soap and water to remove stains.
Pressure Washing: For deep cleaning, use a pressure washer to remove stubborn dirt and grime. Avoid using excessive pressure, as it can damage the surface.

2. Sealcoating

Sealcoating is one of the most important maintenance tasks for asphalt paving. It protects the surface from water damage, UV rays, oil spills, and other environmental factors.

Frequency: Apply sealcoat every 2 to 3 years for driveways and 1 to 2 years for high-traffic areas like parking lots.
Benefits: Sealcoating fills small cracks, restores the surface’s smooth finish, and enhances its appearance.
Professional Application: For best results, hire a professional to apply sealcoat. They have the tools and expertise to ensure even coverage.

3. Crack Filling

Cracks are inevitable in asphalt surfaces due to temperature changes, heavy loads, and aging. If left untreated, small cracks can turn into larger potholes, leading to costly repairs.

Inspect Regularly: Check your asphalt surface for cracks at least twice a year, especially in spring and fall.
Fill Cracks Promptly: Use a high-quality crack filler to seal small cracks before they expand. For larger cracks, consider hiring a professional.
Prevent Water Damage: Filling cracks prevents water from seeping into the base layer, which can cause further damage.

4. Prevent Water Pooling

Water is one of the biggest enemies of asphalt paving. Pooling water can weaken the base layer and lead to cracks, potholes, and other damage.

Ensure Proper Drainage: Make sure your asphalt surface has adequate drainage to prevent water from pooling. Install or maintain gutters, drains, and slopes to direct water away from the pavement.
Repair Low Spots: If you notice areas where water pools, address them immediately. Low spots can be filled and leveled to restore proper drainage.

5. Avoid Heavy Loads

Asphalt is strong, but excessive weight can cause depressions, ruts, and cracks over time.

Limit Heavy Vehicles: Avoid parking heavy trucks, RVs, or construction equipment on your asphalt surface for extended periods.
Use Load Distribution: If heavy loads are unavoidable, use plywood or other materials to distribute the weight evenly.

6. Protect Against Oil and Chemical Spills

Oil, gasoline, and other chemicals can soften asphalt and cause it to deteriorate.

Clean Spills Immediately: Use an absorbent material like cat litter to soak up spills, then clean the area with a degreaser.
Use Drip Pans: Place drip pans under vehicles to catch leaks and prevent spills.

7. Repair Potholes Promptly

Potholes are not only unsightly but also hazardous. They can damage vehicles and pose a safety risk to pedestrians.

Fill Small Potholes: Use cold patch asphalt or a pothole repair kit to fill small potholes. Compact the material thoroughly to ensure a durable repair.
Hire a Professional: For larger potholes or extensive damage, consult a professional paving contractor. They can assess the damage and recommend the best repair method.

8. Avoid Harsh De-Icing Chemicals

In winter, de-icing chemicals like rock salt can damage asphalt by causing it to crack and crumble.

Use Alternatives: Opt for sand or calcium chloride instead of rock salt. These materials are less harmful to asphalt.
Shovel Snow Promptly: Remove snow as soon as possible to minimize the need for de-icing chemicals.

9. Schedule Professional Inspections

Regular inspections by a professional paving contractor can help identify potential issues before they become major problems.

Annual Inspections: Have your asphalt surface inspected at least once a year.
Early Detection: Professionals can spot signs of wear, drainage issues, or structural problems that may not be visible to the untrained eye.

10. Address Vegetation Growth

Weeds and grass growing through cracks can damage your asphalt surface over time.

Remove Vegetation: Pull out weeds and grass as soon as you notice them. Use a weed killer or vinegar solution to prevent regrowth.
Fill Cracks: After removing vegetation, fill the cracks to prevent future growth.

11. Avoid Sharp Objects

Sharp objects like snowplow blades, metal shovels, or heavy equipment can scratch or gouge the asphalt surface.

Use Plastic Tools: Opt for plastic shovels or snowplow blades to minimize damage during snow removal.
Be Cautious: Avoid dragging heavy or sharp objects across the surface.

12. Resurface When Necessary

Even with proper maintenance, asphalt surfaces will eventually show signs of aging. Resurfacing can restore the appearance and functionality of your pavement.

Signs to Resurface: If your asphalt has extensive cracking, potholes, or uneven surfaces, it may be time to resurface.
Professional Resurfacing: Hire a paving contractor to apply a new layer of asphalt over the existing surface. This is more cost-effective than a complete replacement.
