When asphalt begins to show signs of ageing—like cracks, potholes, and surface wear—many property owners face the same question: should you resurface the existing pavement or replace it entirely? Making the right decision can save you time, money, and future headaches. At Berri Road Tech SA, we help clients across Berri, SA understand the difference between resurfacing and replacement so they can choose the most cost-effective and durable option for their needs.
This guide explores both processes, outlines when each is appropriate, and explains what you can expect from the work.
What Is Asphalt Resurfacing?
Asphalt resurfacing involves laying a new layer of hot mix asphalt over an existing surface that still has a structurally sound base. It’s a middle-ground solution that renews the top layer without the expense of full reconstruction.
Key Benefits:
- Less expensive than full replacement
- Faster installation time
- Restores appearance and smoothness
- Extends the life of the existing surface by 8 to 15 years
- Minimal disruption to access and use
Ideal for:
- Surfaces with widespread surface cracking, oxidation or minor potholes
- Areas where the base remains stable and well-drained
- Driveways, car parks, and light-traffic roads with general surface ageing
What Is Asphalt Replacement?
Full asphalt replacement is the process of completely removing the existing surface and rebuilding the pavement from the base up. This may include excavation, base repairs or replacement, and then laying new asphalt layers.
Key Benefits:
- Addresses deep structural issues
- Increases lifespan up to 20+ years with proper maintenance
- Allows for design upgrades, improved drainage or wider layouts
- Ensures maximum strength for heavy traffic or high load zones
Ideal for:
- Surfaces with base failure, extensive potholes or drainage problems
- Driveways or roads with repeated cracking or visible deformation
- Areas with heavy traffic or increased usage demands
- Sites requiring a long-term solution with improved load capacity
How to Tell Which Option Is Right for You
Choosing between resurfacing and replacement depends on the condition of the existing pavement, how the surface is used, and your long-term plans.
Signs Resurfacing Is Sufficient:
- Surface looks aged or grey but is still even
- Cracks are less than 6mm wide and not deep
- No significant base movement or sinking
- Water drains away properly from the surface
- You want a more budget-friendly solution
Signs Replacement Is Needed:
- Potholes keep reappearing in the same locations
- Deep cracks extend through the base layer
- Asphalt is bubbling, heaving or rutting
- Water pools on the surface or drainage is poor
- The pavement has reached 20 years or more of age
The Processes: What to Expect
Resurfacing Process:
- Inspection and repair of minor cracks or potholes
- Cleaning and tack coating the existing surface
- Laying and compacting a new asphalt overlay (usually 25–40mm thick)
- Quick curing—usually ready for use within 24–48 hours
Replacement Process:
- Excavation and removal of existing asphalt and damaged base layers
- Re-grading and compacting the sub-base
- Installation of new base and surface layers
- May involve changes to layout or drainage systems
- Curing and traffic access typically within 48–72 hours, depending on scope
