Whether you’re planning a new driveway, car park or industrial surface, understanding bitumen costs is essential for budgeting your project. At RTB Civil, Queensland’s leading specialists in bitumen surfacing, we believe in transparent pricing so you can make informed decisions with confidence.
Quick answer: In Queensland, bitumen surfacing typically costs between $25 and $65 per square metre, depending on the surface type, preparation requirements and project size. Premium asphalt applications can range from $40 to $85 per square metre for specialised or heavy-duty projects.
Understanding Bitumen Pricing in Australia
Bitumen pricing can vary significantly based on several factors. The type of surface you choose, the condition of the existing base and the overall complexity of the project all influence the final cost per square metre.
Average Bitumen Costs Per Square Metre (2026)
Spray Seal (single coat): $25–$35
Best for residential driveways and light-traffic areas
Spray Seal (double coat): $35–$50
Best for medium-traffic areas requiring longer durability
Asphalt (standard): $40–$65
Ideal for car parks, driveways and commercial areas
Asphalt (premium/heavy duty): $55–$85
Designed for industrial floors and high-traffic zones
Bitumen surfacing (thin layer): $30–$45
Suitable for residential pathways and low-traffic surfaces
What Influences Bitumen Costs?
The cost of bitumen surfacing is not just about the material itself. Several key factors impact the final price.
1. Site Preparation Requirements
Proper preparation is essential for a long-lasting surface. Excavation, removal of existing materials, drainage works and base compaction all add to the cost. A strong, well-prepared base prevents cracking and surface failure over time.
Site preparation can add $15–$40 per square metre, depending on ground conditions and drainage needs.
2. Project Size and Scale
Larger projects generally benefit from economies of scale. A small 50 m² driveway will usually cost more per square metre than a 500 m² car park, as setup, machinery mobilisation and call-out costs are spread across a smaller area.
3. Accessibility and Location
Projects in remote Queensland locations or sites with limited access may attract additional transport and logistics costs. Metro areas such as Brisbane, the Gold Coast and the Sunshine Coast typically offer more competitive pricing due to supplier proximity and reduced travel time.
4. Thickness and Quality Specifications
Standard residential asphalt is usually installed at 25–30 mm thickness. Heavy-duty and industrial surfaces may require 40–50 mm or more, increasing material and labour costs but significantly improving durability.
5. Additional Features
Extras such as drainage systems, kerbing, line marking and specialised finishes increase the overall cost but are often essential for compliance, safety and long-term performance.
Bitumen vs Other Surfacing Options
Bitumen offers an excellent balance between cost, durability and maintenance.
Bitumen/asphalt: $40–$65 per m², lifespan 15–20 years, low to moderate maintenance
Concrete: $65–$110 per m², lifespan 25–30 years, low maintenance
Gravel/crushed rock: $15–$30 per m², lifespan 3–5 years, high maintenance
Pavers: $80–$150 per m², lifespan 20–25 years, moderate maintenance
For many Queensland properties, bitumen delivers the best overall value.
Breaking Down a Typical Bitumen Project Cost
Example: 80 m² Residential Driveway
- Site preparation and base work: $1,600–$2,400
- Asphalt application (40 mm depth): $3,600–$4,800
- Edge trimming and finishing: $400–$600
Total project cost: $5,600–$7,800
Effective cost per square metre: $70–$97
While material costs may appear lower, full project pricing reflects the necessary groundwork and finishing required for a quality result.
Regional Price Variations Across Queensland
- Brisbane metro: Most competitive pricing
- Gold Coast and Sunshine Coast: Similar to Brisbane, with occasional coastal premiums
- Regional centres: Typically 5–15% higher due to transport
- Remote areas: Can be 20–30% higher due to logistics and equipment mobilisation
How to Get the Best Value for Your Bitumen Project
Time Your Project Well
Dry, warm conditions are ideal for bitumen works. Autumn and spring often deliver the best balance of weather and contractor availability.
Combine Multiple Areas
Completing driveways, access roads and car parks as a single project reduces setup costs and may qualify for volume discounts.
Invest in Proper Installation
Spending slightly more on quality base preparation, drainage and materials significantly reduces long-term maintenance and repair costs.
Choose Experienced Contractors
Experienced contractors ensure the job is done correctly the first time. Poor workmanship leads to cracking, drainage issues and costly rework.
Hidden Costs to Consider
Additional costs that may apply include drainage installation, kerbing, line marking, traffic management, council permits and removal of existing surfaces. These should always be clearly itemised in your quote.
Is Bitumen Worth the Investment?
Bitumen provides excellent long-term value. A properly installed surface offers:
- 15–20 years of service life
- Minimal maintenance
- Fast curing and usability
- Excellent performance in Queensland’s climate
- A clean, professional appearance
Over its lifespan, bitumen typically costs just $2–$4 per square metre per year, making it one of the most cost-effective surfacing options available.
Maintenance Costs to Expect
- Seal coating (every 3–5 years): $5–$12 per m²
- Crack sealing: $8–$15 per linear metre
- Minor patch repairs: $25–$45 per m²
- Line marking refresh: $3–$6 per linear metre
Regular maintenance is far more economical than full resurfacing.
Typically $25–$65 per square metre for surface application, with full project costs ranging from $65 to $100+ per square metre.
Spray seal is cheaper upfront, but asphalt offers greater durability and suits higher traffic areas.
With proper installation and maintenance, 15–20 years in Queensland conditions.
Often yes, provided the existing base is structurally sound.
Yes, but requirements are relatively low and affordable when done regularly.
