What Causes Asphalt to Crack?

Asphalt is a flexible pavement material designed to withstand a certain amount of stress. However, over time, environmental and mechanical factors lead to the development of cracks. The main causes include:

• Temperature Fluctuations: Asphalt expands in heat and contracts in cold. Repeated cycles create stress that eventually causes cracks.
• Oxidation: Exposure to oxygen hardens the asphalt binder, making it brittle and prone to cracking.
• Water Damage: Water infiltrates through small cracks or porous surfaces, weakening the base and causing potholes.
• Heavy Traffic Loads: Constant pressure from vehicles, especially heavy trucks, stresses the asphalt and accelerates degradation.
• Poor Installation: Inadequate compaction or improper mix design can lead to premature cracking.

The Different Types of Asphalt Cracks

Alligator Cracking

Characterized by interconnected cracks resembling an alligator’s skin, this type indicates structural failure usually caused by poor base support or excessive loads.

Fatigue Cracking

Repeated stress from traffic causes this cracking, often appearing as multiple cracks parallel to traffic flow.

Thermal Cracking

Occurs due to temperature changes causing contraction, resulting in transverse cracks perpendicular to the road.

Block Cracking

Large rectangular cracks caused by aging and oxidation of the asphalt binder.
