The Science Behind Asphalt Cracking and How to Stop It
Asphalt cracking is a common issue faced by property owners and municipalities alike, especially in cities like Oakville. Understanding the causes and prevention methods can extend the life of your pavement and maintain the safety and appearance of your parking lots and roads. In this article, we dive into the science behind asphalt cracking and effective strategies to combat it.
What Causes Asphalt to Crack?
Asphalt is a durable material, but it is not impervious to damage. Several factors contribute to the formation of cracks over time, including:
- Temperature Fluctuations: Expansion and contraction caused by heat and cold stress the asphalt, leading to cracks.
- Oxidation: Exposure to oxygen and UV rays causes asphalt to become brittle and lose flexibility.
- Water Infiltration: Water seeps into the pavement layers, weakening the underlying base and causing cracks.
- Heavy Traffic Loads: Continuous pressure from vehicles, especially heavy trucks, accelerates wear and cracking.
- Poor Installation or Maintenance: Improper compaction or neglecting regular upkeep can shorten asphalt lifespan.
Types of Asphalt Cracks
Recognizing the different types of cracks can help in selecting the right repair technique. Common types include:
Alligator Cracking
Resembling a reptile’s skin, this interconnected cracking pattern indicates structural failure, often from a weak base.
Longitudinal Cracking
These cracks run parallel to the pavement’s centerline, typically from poor joint construction or thermal stresses.
Transverse Cracking
Cracks perpendicular to the pavement edge caused mainly by temperature changes causing contraction.

- Regular Seal Coating: Applying a protective sealant shields the asphalt from oxidation and water penetration.
- Proper Drainage: Ensuring water does not pool on the surface helps avoid water infiltration and base weakening.
- Timely Crack Filling: Filling cracks as soon as they appear prevents them from widening and causing more damage.
- Quality Installation: Using professional contractors like Capital Parking Lot Line Painting guarantees proper base preparation and asphalt layering.
- Routine Maintenance: Regular inspections and upkeep extend the pavement life significantly.
The Role of Professional Line Painting
