Asphalt surfacing is one of the most effective and versatile solutions for roads, driveways, and car parks across South Australia. However, when done poorly or without proper planning, asphalt can fail prematurely—leading to costly repairs, safety issues, and a poor visual outcome. At Angle Vale Road Tech SA, we’ve seen the difference quality workmanship and materials can make, especially in demanding environments like Angle Vale, SA.
Whether you’re managing a council asset, commercial property, or private driveway, understanding common surfacing pitfalls can help you make better long-term decisions. Here are the top 10 asphalt surfacing fails—and how to avoid them.
1. Poor Base Preparation
The most common and damaging failure starts below the surface.
- An unstable or poorly compacted base causes cracking, sinking, and deformation.
- A solid foundation ensures your asphalt can withstand traffic and environmental pressures.
- Always ensure proper excavation, moisture control, and compaction before surfacing.
2. Inadequate Drainage Design
Water is the enemy of long-lasting asphalt.
- Without effective drainage, water pools and seeps into the sub-base.
- This leads to cracking, potholes, and eventual collapse of the surface.
- Incorporate fall design, kerbing, and channel drains to guide water away.
3. Using Low-Quality Materials
Not all asphalt mixes are created equal.
- Cheap aggregates and low-grade bitumen may save money upfront, but result in early failure.
- They often can’t handle local traffic conditions or climate variability.
- At Angle Vale Road Tech SA, we use high-grade materials suitable for South Australian weather and wear.
4. Incorrect Asphalt Thickness
Applying the wrong layer thickness can drastically reduce surface performance.
- Too thin, and it won’t support the load—especially in commercial or industrial settings.
- Too thick, and it may not bond properly to the base.
- Thickness should be matched to the application—light residential use differs from heavy truck traffic.
5. Poor Compaction During Laying
Compaction is critical to achieve density and surface strength.
- Inadequate rolling leaves air gaps and weak spots.
- These areas absorb water and wear down faster under pressure.
- The surface must be rolled promptly while the asphalt is still workable.
6. Laying Asphalt in the Wrong Weather
Temperature and moisture play a key role in asphalt performance.
- Laying in very cold or rainy conditions prevents proper bonding.
- Bitumen cools too quickly, making it difficult to compact.
- Always schedule surfacing in dry, mild conditions unless using specially modified materials.
7. Ignoring Crack Control Measures
Asphalt naturally expands and contracts.
- Without joint control or preventative maintenance, cracks will appear early.
- Small cracks can let in water and become potholes if left untreated.
- Routine crack sealing and expansion joint design are essential.
8. Poor Edging or Lack of Edge Restraint
Edges take a lot of pressure and are often the first to fail.
- Asphalt should have proper edging support—either with kerbing, concrete strips, or tie-ins to existing structures.
- Soft edges can crumble under vehicle weight or erode with weather.
9. No Sealcoating or Surface Protection
Asphalt is durable, but not invincible.
- Over time, exposure to UV, fuel, and weather breaks down bitumen.
- A protective sealcoat helps extend lifespan and maintain appearance.
- Sealcoating every few years is especially useful in high-use areas around Angle Vale.
10. Lack of Maintenance Planning
Even the best asphalt needs some care.
- Without regular inspections and minor repairs, small issues escalate quickly.
- Schedule maintenance such as crack sealing, patch repairs, and sweeping to extend the surface life.
- Early intervention always costs less than full resurfacing.
