When Is the Right Time of Year to Fill Cracks in Asphalt?

Proper maintenance of asphalt surfaces is key to extending their lifespan and maintaining a safe, attractive parking lot. One crucial aspect of this maintenance is crack filling. But when is the best time to fill cracks in asphalt to ensure long-lasting results? In this article, we explore the optimal timing for crack filling, with insights from Capital Parking Lot Line Painting, a trusted name in parking lot services in North Bay.

Why Crack Filling Matters for Asphalt Maintenance

Cracks in asphalt may seem minor at first, but they can quickly escalate into larger problems if left untreated. Water infiltration through cracks can weaken the base, cause potholes, and lead to costly repairs down the road. Filling cracks promptly helps preserve the integrity of your pavement and keeps your parking lot looking professional.

Understanding Asphalt’s Reaction to Weather

Seasonal Effects on Asphalt

Asphalt expands and contracts with temperature changes. During summer months, the pavement softens and expands, while in winter it contracts and hardens. This natural movement can cause cracks to open and close, which influences when crack filling should be done for maximum effectiveness.

The Impact of Moisture

Moisture is the enemy of asphalt cracks. Water that seeps into cracks can freeze during colder months, causing the cracks to widen through freeze-thaw cycles. This is why timing your crack filling to avoid moisture intrusion is critical.

The Best Time of Year to Fill Cracks

Experts at Capital Parking Lot Line Painting recommend scheduling crack filling during the warmer, dryer months of the year to ensure the filler adheres properly and cures correctly. In North Bay, this typically means late spring through early fall.

  • Late Spring (May to June): Asphalt has fully thawed and is dry, providing the ideal conditions for crack filling.
  • Summer (July to August): Warm temperatures help the filler set quickly and bond well with the pavement.
  • Early Fall (September to October): As long as the weather remains dry and temperatures stay above 10°C (50°F), crack filling can still be effective.

What to Avoid When Filling Cracks

Timing is crucial, but so is preparation and execution. Here are some common mistakes to avoid:

  • Filling cracks when the pavement is wet or during rainy weather.
  • Applying filler in cold temperatures, which prevents proper curing.
  • Ignoring small cracks, which can turn into larger problems.
