The Science Behind Asphalt Cracking and How to Stop It
Asphalt cracking is a common issue faced by property owners, especially in busy urban areas like Cambridge, Ontario. Understanding its causes and prevention methods is essential for maintaining durable and safe parking lots. In this post, Capital Parking Lot Line Painting explores the science behind asphalt cracking and shares effective strategies to stop it.
What Causes Asphalt to Crack?
Asphalt is a mixture of aggregates and bitumen, designed to withstand traffic and weather conditions. However, several factors contribute to its deterioration and cracking over time:
Environmental Stressors
Temperature fluctuations cause asphalt to expand and contract. In colder climates like Cambridge, freeze-thaw cycles are particularly damaging, resulting in stress that leads to cracks.
Traffic Loads
Heavy vehicles and constant traffic exert pressure on asphalt surfaces. Over time, this repeated stress weakens the pavement’s structure, causing fatigue cracks.
Poor Installation or Subgrade Issues
Improper base preparation or inadequate compaction during installation compromises the pavement’s strength. Water infiltration into these weak spots accelerates cracking.
Types of Asphalt Cracks
Identifying the type of crack helps determine the best repair method. Common types include:
- Alligator Cracking: Interconnected cracks resembling an alligator’s skin, often due to structural failure.
- Longitudinal Cracks: Cracks running parallel to the pavement’s centerline, typically caused by paving issues.
- Transverse Cracks: Cracks running perpendicular to the centerline, usually from thermal contraction.
- Edge Cracks: Cracks near the pavement edge caused by poor support or drainage problems.
How to Prevent Asphalt Cracking
Preventing asphalt cracks requires a combination of proactive maintenance and expert services. Here are some key strategies:
1. Regular Sealcoating
Applying a protective sealcoat acts as a barrier against water, UV rays, and chemicals. Sealcoating extends the life of asphalt and helps prevent cracking.
2. Proper Drainage
Ensuring good drainage prevents water from pooling on or under the pavement, reducing the risk of freeze-thaw damage.
3. Timely Crack Filling
Addressing small cracks early with crack filler stops water infiltration and stops cracks from expanding.
4. Expert Installation and Repairs
Hiring professionals like Capital Parking Lot Line Painting in Cambridge guarantees proper base preparation, paving, and line painting, which contribute to longer-lasting asphalt surfaces.
