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

Maintaining your asphalt surfaces is crucial for preserving their longevity and appearance. One key maintenance task is filling cracks at the optimal time of year to prevent further damage. In this post, we explore when you should fill cracks in asphalt and why timing matters, especially for property owners in Peterborough.

Asphalt Crack Filling

Why Is Crack Filling Important?

Asphalt cracks are inevitable due to weather changes, traffic loads, and natural aging. Left untreated, these cracks allow water to seep beneath the surface, which can cause potholes, erosion, and significant damage. Proper crack filling extends the life of your pavement and helps maintain a smooth, safe surface.

Best Time of Year to Fill Asphalt Cracks

Timing is essential when it comes to crack filling. The ideal conditions ensure the filler adheres properly and cures effectively. Here’s what you need to know:

Spring and Early Summer

Spring, once the frost has melted and the pavement is dry, is a prime time for crack repair. The warming temperatures help the filler material bond well with the asphalt. Early summer offers similar benefits with stable weather and low moisture.

Fall

Fall is another excellent season for crack filling. Cooler temperatures but still above freezing mean the asphalt is stable and dry. This season allows you to prepare your pavement for the harsh winter months, preventing water infiltration and freeze-thaw damage.

Why Avoid Winter and Mid-Summer?

  • Winter: Cold temperatures cause asphalt to contract, and moisture presence can prevent the filler from sealing properly.
  • Mid-Summer: Excessive heat can cause the filler to dry too quickly or become overly soft, reducing its effectiveness.

Steps to Proper Crack Filling

To get the best results, follow these essential steps when filling cracks in asphalt:

  • Clean the cracks thoroughly: Remove dirt, debris, and vegetation to ensure adhesion.
  • Dry the area: Moisture can weaken the bond, so wait for dry conditions.
  • Apply the crack filler: Use a high-quality filler suited for the size and type of crack.
  • Smooth and level: Make sure the filler is flush with the pavement surface.
  • Allow curing time: Avoid traffic until the filler has fully set.
