The Science Behind Asphalt Cracking and How to Stop It
Asphalt cracking is a common issue faced by many property owners in Ottawa and beyond. Understanding why asphalt cracks and how to effectively prevent it can save you time, money, and hassle in the long run. In this post, we dive into the science behind asphalt cracking and share practical solutions offered by experts like Capital Parking Lot Line Painting.
What Causes Asphalt to Crack?
Asphalt is a durable paving material, but it isn’t impervious to damage. Over time, various factors contribute to cracking, including:
- Thermal Expansion and Contraction: Asphalt expands in hot weather and contracts when it’s cold. Repeated cycles weaken the pavement and cause cracks.
- Water Penetration: Water seeps into tiny gaps, weakening the base and causing the asphalt to break apart under pressure.
- Heavy Traffic Loads: Constant pressure from vehicles, especially heavy trucks, causes stress fractures.
- Poor Installation or Materials: Incorrect mixing or laying of asphalt can lead to premature cracking.
- UV Radiation: Sunlight breaks down the asphalt binder, making it brittle and prone to cracking.
The Types of Asphalt Cracks
Recognizing the type of crack can help you understand the underlying cause and the best repair method. Common types include:
Alligator Cracking
Looks like a series of interconnected cracks resembling an alligator’s skin, usually caused by structural failure.
Fatigue Cracking
Develops under repeated traffic loads leading to surface breakdown.
Block Cracking
Large rectangular cracks caused by asphalt shrinkage as it ages.
Edge Cracking
Occurs at the pavement edges due to poor support or drainage issues.
How to Prevent Asphalt Cracking
Preventing asphalt cracks requires a combination of good materials, proper installation, and ongoing maintenance. Here are key steps to consider:
- Quality Installation: Hiring experienced professionals like Capital Parking Lot Line Painting in Ottawa ensures the right mix and proper layering of asphalt.
- Sealcoating: Applying a protective sealcoat prevents water infiltration and UV damage, extending the pavement’s life.
- Regular Maintenance: Early crack filling stops small cracks from becoming bigger issues.
- Proper Drainage: Ensuring water drains away from the pavement base reduces water damage.
- Controlled Traffic Loads: Managing heavy vehicle traffic and avoiding overloading prevents stress cracks.
