Asphalt is one of the most durable and cost-effective surfacing options available, but like any material, it requires regular maintenance to retain its performance and appearance. Knowing whether to seal, patch, or replace your asphalt surface is crucial for maximising its lifespan and avoiding unnecessary costs. At Labrador Surfacing Solutions, we help clients across Labrador, QLD make smart maintenance decisions tailored to the condition of their asphalt. This guide outlines how to assess your surface and choose the right treatment at the right time.
Understanding Asphalt Deterioration
Asphalt naturally ages due to:
- UV exposure
- Traffic loading
- Moisture infiltration
- Temperature fluctuations
Over time, this leads to fading, cracking, potholes, and eventual structural failure if left unaddressed. Early action can prevent minor issues from becoming major problems.
When to Seal: Preventative Maintenance for Healthy Asphalt
Sealing is ideal for relatively new or well-maintained asphalt that is beginning to show signs of surface oxidation or light wear.
Indicators sealing is the right choice:
- Asphalt is 1–3 years old or newly resurfaced
- Surface is fading to grey but remains smooth and intact
- Very minor hairline cracks visible
- No structural damage or potholes present
Benefits of sealing:
- Restores black appearance and surface oils
- Protects against water penetration and UV damage
- Extends the lifespan of the asphalt
- Ideal for driveways, car parks, and access roads
At Labrador Surfacing Solutions, we recommend sealing asphalt every 3–5 years in high-exposure areas across Labrador.
When to Patch: Localised Repair for Isolated Damage
Patching is suitable when specific areas of the surface have deteriorated while the majority remains structurally sound.
Indicators patching is the right choice:
- Potholes, depressions, or cracks in isolated areas
- Damage caused by tree roots, edge breakdown, or minor base movement
- Surface is generally in good condition elsewhere
- Drainage and slope still perform correctly
Benefits of patching:
- Targets the problem area without disturbing the rest of the surface
- Cost-effective compared to full replacement
- Prevents small failures from spreading
Patching may involve cutting out the affected section and replacing it with new hot mix asphalt or applying a surface patch if the damage is shallow.
When to Replace: The Surface Has Reached End-of-Life
Replacement becomes necessary when the surface is extensively damaged or the base has failed.
Indicators replacement is the right choice:
- Widespread cracking, alligator cracking, or multiple potholes
- Drainage issues or base instability
- Surface more than 15–20 years old
- Prior patching or sealing no longer effective
Benefits of full replacement:
- Restores full surface strength and function
- Allows for updated drainage design if needed
- Offers a fresh, uniform appearance with a long lifespan
Replacement may include complete excavation and base reconstruction or full-depth resurfacing, depending on the underlying condition.
