Crackfilling for Newly Paved vs. Aged Asphalt Surfaces
Maintaining asphalt surfaces is essential for prolonging their lifespan and appearance. Whether your lot is freshly paved or showing signs of age, crackfilling is a critical component of upkeep. In this post, we explore the differences in crackfilling approaches for newly paved versus aged asphalt, with expert insights from Capital Parking Lot Line Painting in Thunder Bay.
Understanding Asphalt Crackfilling
Cracks in asphalt develop over time due to weather fluctuations, traffic load, and natural wear and tear. Crackfilling involves sealing these fissures to prevent water infiltration, which can cause further damage such as potholes and base erosion. Proper crackfilling not only extends the life of your pavement but also enhances safety and appearance.
Crackfilling Newly Paved Asphalt
Newly paved asphalt surfaces, common in growing cities like Thunder Bay, require special considerations when it comes to crackfilling. Although fresh asphalt is typically free of significant cracks, minor shrinkage cracks may appear as the pavement cures.
Key Characteristics
- Minimal cracking, often hairline or shrinkage cracks
- Surface still curing, requiring careful timing for crackfilling
- High elasticity in the asphalt binder
Best Practices
Capital Parking Lot Line Painting recommends waiting until the new asphalt has sufficiently cured—usually 6 to 12 months—before performing crackfilling. This ensures the pavement has stabilized and the crackfilling material will bond effectively. Early crackfilling on uncured asphalt can lead to poor adhesion and failure of the repair.
Crackfilling Aged Asphalt Surfaces
Aged asphalt surfaces, common in established areas of Thunder Bay, often exhibit a range of cracking types including alligator, edge, and longitudinal cracks. These cracks compromise the integrity of the pavement and require prompt attention.
Key Characteristics
- Visible, often interconnected cracks
- Brittle, oxidized asphalt binder
- Potential underlying base damage
Best Practices
For aged asphalt, Capital Parking Lot Line Painting advises a thorough cleaning of cracks followed by appropriate crackfilling using rubberized sealants designed to accommodate pavement movement. In some cases, crackfilling is combined with sealcoating or patching to maximize surface protection and longevity.
Common Benefits of Crackfilling for All Asphalt Types
- Prevents water from penetrating and damaging the base
- Reduces the spread of cracks and potholes
- Extends overall pavement lifespan
- Improves safety by maintaining a smooth surface
- Enhances curb appeal, especially important for commercial parking lots
Typical Mistakes to Avoid When Crackfilling
- Applying sealant to wet or dirty cracks
- Crackfilling too soon on newly paved surfaces
- Ignoring underlying base damage
- Using inappropriate materials for crack size or type
- Failing to pair crackfilling with routine maintenance like line painting
