It’s not unusual for asphalt surfaces to develop cracks over time—especially under Australia’s harsh sun and changing weather conditions. But not all cracks are the same. Some are minor and expected, while others signal a deeper issue that requires immediate attention. At Booval Surfacing Solutions, we specialise in identifying and addressing asphalt cracks before they evolve into costly repairs.
If you’re in Booval, QLD, and have noticed cracks forming in your driveway, car park, or road surface, it’s important to understand when they’re normal and when to take action.
Why Asphalt Cracks Over Time
Natural Ageing and Wear
Asphalt is flexible and designed to withstand expansion, contraction, and moderate pressure. However, over time and with repeated traffic, exposure to UV rays, and moisture, the surface begins to deteriorate.
Common causes of cracking include:
- Temperature fluctuations
- Water penetration
- Heavy or frequent vehicle loads
- Poor base preparation or compaction
- Lack of routine maintenance
Types of Asphalt Cracks and What They Mean
Hairline Cracks
These are small, surface-level cracks that typically appear as the asphalt ages. They’re usually not urgent but should be monitored. Left untreated, they can expand and allow water to seep into the base.
Block Cracks
Characterised by a square or rectangular pattern, block cracks usually result from asphalt shrinkage or oxidation. They indicate the binder is becoming brittle, and the surface may require sealing or resurfacing.
Alligator Cracks
Named for their resemblance to reptile skin, alligator cracks point to structural failure beneath the surface. This pattern suggests significant weakness in the base or subgrade and often requires full-depth repairs.
Edge Cracks
Found along the sides of the pavement, edge cracks are caused by poor support or drainage issues. These should be addressed quickly to prevent crumbling and further spread.
Longitudinal and Transverse Cracks
These cracks run either parallel or perpendicular to traffic flow. They can result from poor joint construction, seasonal movement, or base instability.
When to Take Action
Signs It’s Time to Act
Cracks should be repaired if you notice:
- Widening or deepening gaps
- Water pooling in or around the crack
- Crumbling edges or loose material
- Spreading patterns, such as alligator cracking
- Multiple types of cracks appearing simultaneously
Risks of Delaying Repairs
Leaving cracks untreated can lead to:
- Moisture entering and weakening the base
- Rapid surface deterioration
- Formation of potholes
- Increased repair costs due to larger affected areas
Timely intervention is always more affordable and more effective than major reconstruction down the line.

Keeping Asphalt Healthy in Booval’s Climate
Local Conditions Matter
Booval’s climate presents unique challenges to asphalt surfaces, including intense sun exposure, seasonal rain, and general wear from residential and light commercial traffic. Regular inspections and surface treatments can keep cracks from compromising your asset.
Ongoing Surface Management
Routine maintenance doesn’t just fix existing problems—it prevents new ones from forming. We recommend:
- Annual surface inspections
- Prompt crack sealing
- Resealing every few years to protect against oxidation and water damage
Conclusion
Yes, some cracks in asphalt are normal—but they should never be ignored. The key is knowing which ones are harmless and which ones are early signs of deeper issues. Acting early helps preserve your surface, protect your investment, and reduce the risk of expensive repairs later on.
