Asphalt driveways are a popular choice for residential and commercial properties due to their durability and clean, professional finish. However, even the best-laid asphalt surfaces can develop cracks or surface defects if not properly maintained. At Wagga Wagga Road Tech in Wagga Wagga, NSW, we understand the importance of long-term surface health and want to help you get the most out of your driveway investment.
Keeping your asphalt driveway smooth and crack-free doesn’t have to be complicated, but it does require regular care and an understanding of what affects its lifespan.
Why Asphalt Driveways Develop Cracks
Even high-quality asphalt will begin to show signs of wear over time. Cracks can form due to:
- UV exposure drying out the binder
- Water infiltration weakening the sub-base
- Excessive vehicle weight causing stress fractures
- Tree root intrusion beneath the surface
- Temperature fluctuations leading to expansion and contraction
With the right preventative strategies, you can reduce the likelihood of these problems developing and keep your driveway looking and functioning its best.
Routine Maintenance That Makes a Difference
Regular Cleaning
Dirt, leaves, fuel, and oil spills can degrade the asphalt surface over time. Sweeping your driveway regularly and removing any spills immediately will help prevent damage. Oil spills in particular can soften the surface, leading to early breakdown.
Sealcoating Every Few Years
Applying a professional sealcoat helps protect your asphalt driveway from UV rays, moisture, and chemical spills. For most residential surfaces, sealcoating every 2–3 years is ideal to maintain strength and appearance.
Addressing Minor Cracks Promptly
Small cracks might seem harmless, but they act as entry points for water. Once water penetrates the surface, it can freeze, expand, and worsen the damage. Using high-quality crack filler early on prevents deeper structural issues later.
Surface Drainage and Water Run-Off
Ensure Proper Drainage
One of the most overlooked causes of cracking is standing water. Pooling can soften asphalt and wash out the sub-base. Your driveway should have a gentle slope away from buildings and toward stormwater drains or garden areas.
Keep Edges Supported
Asphalt edges without proper support are more prone to crumbling. Edging your driveway with concrete strips or maintaining adjacent lawn height helps prevent lateral movement and edge deterioration.
Managing Traffic Load
Avoid Heavy Loads
If your driveway wasn’t built for high loads, try to avoid parking large trucks, boats on trailers, or caravans for extended periods. These vehicles can exert stress on the surface and lead to rutting or cracking.
Rotate Parking Patterns
Even everyday vehicles can leave permanent marks when parked in the same spot over and over. Shifting your parking spot occasionally allows even load distribution and reduces the chance of surface deformation.
Seasonal Maintenance Tips
- In summer: Water the edges lightly during heatwaves to reduce drying and cracking
- In winter: Remove debris and avoid letting ice or snow compact onto the surface
- After storms: Clear gutters and downpipes to redirect water away from the driveway
When to Call in the Professionals
Some issues go beyond DIY maintenance. If you notice:
- Widespread cracking
- Sinking sections
- Water not draining properly
- Soft spots or surface bubbling
It may be time to bring in experts from Wagga Wagga Road Tech in Wagga Wagga, NSW to inspect and professionally resurface the area if required.
