Asphalt surfaces are built for durability, but even the best-laid driveways, car parks, and access roads require maintenance over time. One of the most important yet often overlooked aspects of asphalt care is regular resealing. A protective seal coat acts as a barrier against moisture, UV rays, fuel spills, and general wear—preserving the integrity of your surface and extending its lifespan.
At Camberwell Road Tech in Camberwell, VIC, we help property owners maintain high-performing asphalt surfaces through timely resealing and preventative maintenance. In this article, we outline the key signs that your asphalt surface may be due for resealing and what can happen if it’s ignored.
Why Resealing Matters
Seal coating provides a protective layer over your asphalt that helps prevent oxidation, water penetration, and softening caused by oil or fuel. Without it, the bitumen binder in the asphalt begins to break down, leading to cracks, discolouration, and surface failure.
Regular resealing:
- Extends the life of the asphalt
- Enhances appearance and kerb appeal
- Prevents costly repairs and early replacement
- Protects against weather and chemical damage
Depending on usage and environmental conditions, resealing is typically recommended every 3–5 years.
Common Signs Your Asphalt Surface Needs Resealing
1. Fading or Greying Surface Colour
Freshly sealed asphalt is dark and rich in colour. Over time, exposure to sunlight and oxygen causes oxidation, fading the surface to a dull grey.
- A faded surface indicates the seal coat has worn away
- Oxidised asphalt becomes brittle and more prone to cracking
- Colour change is an early warning of structural decline
In Camberwell’s variable weather conditions, UV exposure is a major factor in asphalt ageing.
2. Small Surface Cracks (Hairline Cracks)
If you begin to notice small cracks forming across the surface, it’s a clear sign the protective barrier has worn off and the asphalt is drying out.
- Cracks allow water to enter the sub-base, causing further damage
- Often caused by traffic stress or thermal expansion
- Early resealing can fill and seal small cracks before they worsen
Timely intervention with a seal coat helps prevent the progression to larger fractures and potholes.
3. Loss of Water Beading
A freshly sealed asphalt surface will repel water effectively. If rainwater no longer beads and instead absorbs into the surface, the sealant has likely broken down.
- Water absorption weakens the asphalt over time
- Leads to soft spots, deformation, and erosion
- Creates ideal conditions for freeze-thaw damage in colder months
Checking water behaviour after rainfall is a simple way to assess your surface’s condition.
4. Oil and Fuel Stains That Don’t Wash Off
Seal coats act as a shield against oil, fuel, and chemical spills. If you notice stains from leaks that aren’t easily cleaned, the asphalt may be unprotected.
- Oil softens bitumen and weakens surface strength
- Stains contribute to surface breakdown and cracking
- Sealing restores the protective barrier against corrosive materials
This is especially relevant for driveways, service areas, and commercial car parks with regular vehicle movement.
5. Rough, Uneven or Dry Texture
A sealed asphalt surface should feel smooth and tightly bound. When it starts to feel gritty or flaky, the aggregate is likely becoming exposed due to binder degradation.
- Loss of smooth finish reduces visual appeal
- Indicates surface layer is beginning to wear away
- Exposed aggregate signals the need for sealing or resurfacing
This is a key aesthetic and structural sign that resealing is due.
Additional Factors to Consider
Resealing frequency can vary depending on:
- Traffic volume and load weight
- Sun exposure and local climate
- Age and condition of the original surface
- Type of vehicles (e.g., heavy trucks, frequent turning)
If your asphalt surface in Camberwell has been exposed to harsh conditions or hasn’t been sealed in several years, it’s wise to schedule an inspection with an experienced contractor.
