Asphalt surfacing remains one of the most reliable solutions for roads, driveways, and car parks throughout regional and coastal areas. However, even high-quality surfaces can develop problems over time if not installed or maintained properly. One common issue is surface bleeding—a shiny, sticky film that appears when bitumen rises to the surface. At Cabarita Beach Surfacing Solutions in Cabarita Beach, NSW, we take a proactive approach to preventing surface bleeding and other performance-related concerns.
Understanding the causes and solutions helps ensure a durable and safe asphalt surface.
What Is Asphalt Surface Bleeding?
Surface bleeding occurs when excess bitumen moves to the top of the asphalt layer. This creates a slick, shiny appearance and can significantly reduce surface friction, making roads and driveways slippery—particularly dangerous in wet conditions.
Bleeding typically occurs in hot climates or when bitumen content is too high.
Key Causes of Surface Bleeding and Related Issues
Several factors contribute to asphalt bleeding and other early-stage failures:
- Excessive binder content – Too much bitumen in the mix leads to bleeding under heat or traffic pressure.
- Insufficient air voids – Poor compaction traps the binder, giving it nowhere to go but up.
- High surface temperatures – Warm climates like those in northern NSW intensify softening and upward migration of bitumen.
- Over-application of spray seal – Applying too much binder during a seal coat traps it near the surface.
- Poor drainage – Water sitting on the surface contributes to stripping, raveling, and premature ageing.
How to Avoid Bleeding and Other Surface Issues
At Cabarita Beach Surfacing Solutions, we focus on prevention through careful design, preparation, and execution.
Choose the Right Asphalt Mix
Selecting a mix that suits the climate and expected traffic load is essential. For hotter regions like Cabarita Beach, a harder grade of bitumen and reduced binder content are ideal to withstand softening.
Ensure Proper Compaction
Achieving optimal compaction ensures there’s enough air void space in the asphalt to absorb binder movement without pushing it to the surface.
Control Binder Application in Spray Seals
When applying spray seal, the binder rate must be carefully calculated based on traffic volume, pavement texture, and environmental conditions. Over-application is a common mistake that can be easily avoided with experience.
Schedule Regular Surface Inspections
Early detection is key. We recommend inspections to identify early signs of:
- Binder flushing or bleeding
- Rutting or depressions
- Cracking or stripping
- Surface polishing and loss of texture
Timely maintenance prevents these issues from escalating into costly repairs.
Promote Efficient Drainage Design
Water left sitting on asphalt accelerates deterioration. We design surfaces with proper slope and ensure drainage channels are clear and functional.
When Repairs Are Necessary
If bleeding has already occurred, the solution depends on the extent of the damage. In minor cases, sand or fine aggregate may be spread to restore surface texture. More serious bleeding might require removal and replacement of the affected layer.
We assess each situation and recommend solutions that extend the life of the surface while restoring safety.
Conclusion
Preventing surface bleeding and other asphalt failures starts with expert planning and finishes with consistent maintenance. At Cabarita Beach Surfacing Solutions in Cabarita Beach, NSW, we deliver asphalt and bitumen surfacing that stands up to local conditions and long-term use.
