Asphalt surfaces are known for their durability, flexibility, and clean black finish—but over time, exposure to sunlight, air, and water can cause them to oxidise and fade. In regions like Bendigo, VIC where hot, dry summers and UV exposure are common, these effects can appear sooner than expected if preventative steps aren’t taken. At Bendigo Road Tech, we provide expert surfacing and maintenance services to help protect asphalt from premature deterioration.
Understanding what causes oxidation and fading—and how to stop it—can significantly extend the life and appearance of your asphalt surface.
What Is Asphalt Oxidation?
Oxidation is a natural chemical reaction where the asphalt binder (the bitumen component) is exposed to oxygen and ultraviolet (UV) rays. This process breaks down the oils in the binder, causing the surface to become brittle, dry, and light grey in colour.
Signs of oxidation and fading:
- Fading from deep black to light grey
- Hairline cracks on the surface
- Surface dryness and loss of flexibility
- Sand or fine aggregate loosening on top layer
Once oxidation sets in, the surface is more vulnerable to cracking, water penetration, and general wear—especially under vehicle traffic.
Why Oxidation Is a Problem
Many people see faded asphalt as a cosmetic issue, but it’s actually the first stage of structural decline. If ignored, it can lead to significant surface failure and costly resurfacing needs down the line.
Risks of untreated oxidation:
- Accelerated cracking and pothole formation
- Loss of waterproofing ability
- Increased repair and maintenance costs
- Reduced safety due to surface texture loss
At Bendigo Road Tech, we address oxidation early to preserve both the integrity and appearance of our clients’ surfaces.
1. Sealcoating for UV and Moisture Protection
Sealcoating is one of the most effective ways to prevent oxidation and fading. It involves applying a protective coating over the asphalt surface to block out air, sunlight, and water.
Benefits of sealcoating:
- Restores a rich black appearance
- Blocks UV rays and prevents oxidation
- Provides a water-resistant barrier
- Helps preserve flexibility and extend surface life
Sealcoating should typically be applied every 3 to 5 years, depending on traffic, weather exposure, and overall wear.
2. Routine Cleaning and Surface Care
Dust, leaves, oils, and debris can trap moisture and promote faster surface breakdown. Regular sweeping and cleaning helps preserve the surface’s condition and improves the effectiveness of any protective treatments.
Simple maintenance practices:
- Sweep away organic material regularly
- Clean oil spills promptly to prevent staining and breakdown
- Keep edges and drainage areas clear of blockages
- Avoid letting water pool on the surface
Proper upkeep is especially important for driveways, car parks, and industrial surfaces in areas like Bendigo where temperature extremes can impact material behaviour.
3. Crack Sealing to Prevent Water Infiltration
Even small cracks allow oxygen and water to penetrate the surface and accelerate oxidation. Sealing cracks early keeps moisture out and stops the spread of damage.
Crack sealing helps by:
- Reducing the rate of oxidisation beneath the surface
- Protecting the sub-base from erosion
- Preventing small cracks from turning into potholes
- Extending the life of the overall pavement
At Bendigo Road Tech, we use high-quality sealing materials to ensure long-lasting results that blend seamlessly with your existing surface.
4. Schedule Timely Inspections and Maintenance
Not all signs of oxidation are visible to the untrained eye. Scheduling regular inspections with a professional surfacing contractor ensures any early damage is identified and addressed before it becomes costly.
Inspection benefits:
- Accurate condition assessment
- Tailored maintenance recommendations
- Early detection of fading, wear, and structural concerns
- Planning for resealing or resurfacing at the right intervals
This proactive approach gives you more control over the lifecycle of your bitumen or asphalt surface.
Conclusion: Keep Your Asphalt Looking and Performing Its Best
Oxidation and fading are inevitable if asphalt surfaces are left untreated, but with proper maintenance, these effects can be greatly delayed. Regular sealcoating, cleaning, crack sealing, and inspections all work together to preserve the look and structural performance of your bitumen surfaces.
