These driveways require a longer installation process compared to asphalt. They are highly resistant to weather changes and daily wear. Concrete takes more time to cure but provides a solid, long-lasting surface. Concrete driveways can be customised with various colours and finishes, making them aesthetically versatile.
The cost of a concrete driveway in Australia varies depending on factors like slope and thickness. Generally, expect to pay between AUD $25 and $40 per square metre. This makes them more expensive initially, but the long-term durability can offset the higher upfront costs.
Asphalt Driveway Features
Asphalt driveways are generally cheaper to install compared to concrete.
- The main material used in asphalt is a mix of aggregates bound with a binder, usually bitumen or tar, which are petroleum products. An asphalt driveway can be installed relatively quickly, which is an advantage for those needing rapid project completion.
- In terms of lifespan, asphalt driveways typically last between 20 and 30 years. They are more flexible than concrete, making them less prone to cracking under heavy loads and fluctuating temperatures. However, asphalt requires regular maintenance, such as sealing, to prolong its life.
- Asphalt is a softer material than concrete, which contributes to its flexibility but also makes it more susceptible to damage from heavy loads.
- Cost is a significant factor for those considering an asphalt driveway. In Australia, the costs range from AUD $25 to $40 per square metre. This makes asphalt an economical choice, particularly for large driveways. Regular maintenance is essential to keep the driveway in good condition and maximise its lifespan.
The choice between a concrete driveway and an asphalt driveway should be based on budget, aesthetic preference, and long-term maintenance considerations.
Initial Installation and Costs
The installation process and costs for concrete and asphalt driveways differ significantly. Both initial costs and longevity play critical roles when deciding between the two materials.
Concrete Driveway Installation Process
Installing a concrete driveway involves several steps.
- First, the area must be excavated and levelled. This means removing any grass, roots, or old driveway material.
- Next, a sub-base is placed, typically comprising compacted gravel, providing a stable foundation for the concrete.
- Once the sub-base is prepared, wooden forms are set to hold the concrete in shape during the pouring process.
- Reinforcement, usually steel rebar or wire mesh, is then placed within the forms to increase the driveway’s strength and durability. The concrete mixture is poured into the forms, spread evenly, and levelled using specialised tools.
- After pouring, the surface is smoothed and given a finish, which can include brushing for texture or stamping for decorative patterns.
- Finally, the concrete must cure for at least a week before it can handle vehicle traffic.
The cost for a concrete driveway generally ranges from $4 to $15 per square foot, as noted by Home Inspection Insider.

Asphalt Driveway Laying Technique
Laying an asphalt driveway also begins with excavation and removal of any existing material.
- Proper drainage systems are vital to ensure longevity and prevent future issues. The area is graded and sloped to allow for effective water drainage.
- A sub-base typically made of gravel is laid and compacted, much like the preparation for concrete.
- The asphalt mix, which includes aggregates and bitumen, is heated to high temperatures before being spread over the sub-base.
- Once the hot mix is laid, it is compacted using heavy rollers to create a smooth and durable surface. The process is faster compared to concrete as asphalt cools and hardens more quickly.
Depending on the driveway’s size, it can be ready for use within 24 to 48 hours. Cost-wise, asphalt driveways are priced between $2 and $5 per square foot, as detailed by Melbourne Asphalts and Bitumen.
