A Practical Guide to Asphalt Maintenance

The goal of any commercial parking lot asphalt maintenance plan is simple:

Create a clean and visually appealing lot that extends the life of the pavement while ensuring the safety of employees, visitors, and the public.

Common Maintenance Tasks Include:

  • Crack Filling – Prevents water infiltration and further damage
  • Pothole Repair – Restores surface integrity and safety
  • Asphalt Sealcoating – Protects against environmental and chemical damage
  • Sweeping – Keeps surfaces clean and debris-free
  • Commercial Parking Lot Line Striping – Enhances organization and visibility in parking areas


Understanding Asphalt Pavement

Modern asphalt is a blend of:

  • Stone aggregate
  • Mineral filler
  • Asphalt binder

It’s widely used because of its:

  • Waterproofing capabilities
  • Flexibility under pressure
  • Adhesive properties that bind materials together

How Asphalt Deteriorates

Over time, asphalt naturally begins to crack. If left untreated, water seeps into the base layer, weakening the pavement’s structure. This leads to:

  • Rutting
  • Shifting
  • Alligator cracking (interconnecting cracks that mimic the skin of an alligator)

Eventually, the damage may require costly overlays or full replacement.

Why Sealcoating Matters for Commercial Parking Lot Maintenance

Despite its durability, asphalt is vulnerable to:

  • Decay from sun and weather
  • Damage from salts and chemicals
  • Breakdown from oil, gasoline, and other petroleum products

Sealcoating: The Protective Solution

Sealcoating creates a barrier that shields asphalt from environmental and chemical threats. It’s especially effective in low-traffic areas and offers a cost-efficient way to:

  • Slow down aging
  • Preserve appearance
  • Maintain functionality
  • Extend parking lot life

Benefits of Sealcoating

When applied properly and at the right intervals, sealcoating delivers several advantages:

  1. Improved Appearance – Restores a fresh, dark finish
  2. Protection from Decay Caused by Water – Prevents premature aging
  3. Resistance to Oil and Gas Spills – Minimizes chemical damage
  4. UV Ray Protection – Reduces sun-related deterioration
  5. Easier Maintenance – Simplifies cleaning and upkeep
  6. Enhanced Flexibility – Helps pavement withstand pressure
  7. Long-Term Cost Savings – Reduces the need for major repairs

Best Time to Sealcoat Your Commercial Parking Lot

The best time to sealcoat a parking lot is during late spring, summer, or early fall when temperatures are consistently warm, ideally between 55°F and 90°F, and there is no rain forecasted for at least 24-48 hours after application.

Final Thoughts

Sealcoating is ideal for off-highway surfaces such as:

  • Commercial Parking lots
  • Driveways
  • Lightly Traveled roads
  • Runways
  • Service stations
  • Heliports

How Often to Sealcoat Your Parking Lot

Frequency matters: To maximize benefits, sealcoating should be reapplied every 3 to 5 years.
