Concrete pavement is a durable, long-lasting surface suitable for residential driveways, commercial parking areas, and industrial roads. Proper pavement design requires consideration of traffic loads, soil conditions, climate factors, and intended use. Quality concrete pavement can last 30-40 years with minimal maintenance, making it a cost-effective choice for high-traffic areas.
The American Concrete Pavement Association provides extensive resources on pavement design and construction. In Australia, pavement specifications typically follow guidelines from Austroads for road construction and local council requirements for residential applications.

Standard residential driveways require 100-150mm thickness with 25-32 MPa concrete. Steel mesh reinforcement recommended for crack control. Suitable for passenger vehicles and light trailers. Typical width 3-3.5 metres for single car access.
Commercial parking areas need 175-200mm thickness with 32-40 MPa concrete for continuous vehicle traffic. Heavy-duty reinforcement essential for load distribution. Requires proper drainage design and acoustic considerations in residential areas.
Walkways and footpaths typically use 75-100mm thickness with 25 MPa concrete. Light reinforcement or fiber-reinforced concrete prevents cracking. Ideal for balcony access and garden pathways with decorative finish options.
Heavy-duty industrial roads require 200-300mm thickness with 40-50 MPa concrete. Steel rebar grid provides superior strength for truck traffic and point loads. Essential for access roads serving commercial facilities.
Convert thickness from millimetres to metres by dividing by 1000. Standard concrete truck capacity is 6-8m³. Add wastage percentage to account for spillage and over-excavation.

| Application Type | Thickness | Concrete Grade | Reinforcement |
|---|---|---|---|
| Residential Driveway (Light) | 100-125mm | 25-32 MPa | SL72 mesh or fiber |
| Residential Driveway (Heavy) | 150mm | 32 MPa | SL82 mesh |
| Commercial Parking Light | 175mm | 32-40 MPa | SL92 mesh |
| Commercial Parking Heavy | 200mm | 40 MPa | Rebar grid (N12@300) |
| Industrial Road/Loading Bay | 250-300mm | 40-50 MPa | Heavy rebar (N16@200) |
| Pedestrian Pathway | 75-100mm | 25 MPa | Fiber or light mesh |
Soil bearing capacity significantly affects pavement performance. Clay soils require thicker base layers (150-200mm) to prevent differential settlement and cracking. Sandy soils with good drainage need minimal base preparation (75-100mm). Reactive clay soils may require geotechnical assessment and specialized base design including geotextile fabric separation layers.
Concrete pavement reinforcement controls cracking and improves load distribution. Steel mesh (SL72, SL82, SL92) is most common for residential and light commercial applications. The mesh should be positioned at mid-depth of the slab for maximum effectiveness. Steel rebar grids provide superior strength for heavy-duty applications but require professional installation and proper spacing.
For air conditioner pads and aggregate base layers, lighter reinforcement or fiber-reinforced concrete provides adequate crack control without excessive cost.
Concrete pavement costs in 2026 vary significantly based on location, access, and project complexity. Ready-mix concrete prices range from $180-250 per cubic metre depending on strength grade and delivery distance. Labour costs average $65-95 per square metre including excavation, base preparation, formwork, placement, and finishing. Total project costs typically range from $100-180 per square metre for residential driveways.
Control joints manage concrete shrinkage and direct cracking to predetermined locations. Joints should be saw-cut within 12-24 hours after placement to 25-30% of slab depth. Joint spacing typically ranges from 3-4 metres for residential driveways to 5-6 metres for commercial pavements. Proper joint sealing with flexible polyurethane prevents water infiltration and extends pavement life.
Austroads provides pavement design guides and specifications for Australian conditions. AS 3600 covers concrete structures including pavement design requirements and reinforcement details.
Austroads →Concrete Institute of Australia offers technical publications, training courses, and professional certifications for concrete construction including pavement applications.

Boral Concrete →Concrete quantity depends on driveway dimensions and thickness. For a typical single-car driveway (5m × 3m × 125mm thick), you need approximately 1.9m³ of concrete. A standard double driveway (6m × 5.5m × 125mm) requires about 4.1m³. Use our calculator above with your specific dimensions for accurate quantities. Always add 5-10% wastage allowance for residential projects to account for spillage and over-excavation.
Standard residential driveways require 100-125mm thickness for passenger vehicles. If you regularly park trailers, boats, or caravans, increase to 150mm thickness. Commercial driveways with delivery trucks need 175-200mm. The thickness depends on soil conditions—poor soil may require additional thickness or enhanced base preparation. Always use properly compacted roadbase under the concrete regardless of thickness.
Yes, reinforcement is strongly recommended for all concrete pavements. Steel mesh (SL72 or SL82) is standard for residential driveways and controls crack width and spacing. Fiber reinforcement offers easier installation and good crack control for DIY projects. Heavy-duty applications require steel rebar grids. Unreinforced concrete will develop shrinkage cracks—reinforcement doesn't prevent cracks but keeps them tight and prevents structural failure.
Concrete driveway costs in 2026 range from $100-180 per square metre professionally installed, depending on location, access, and finish type. A typical 40m² single driveway costs $4,000-7,200 including excavation, base, concrete, reinforcement, and standard broom finish. DIY projects can reduce costs to $60-90/m² if you handle excavation and base preparation. Decorative finishes like exposed aggregate or stamped patterns add $30-60/m² to the total cost.
New concrete pavement requires minimum 7 days curing before light vehicle traffic. For full strength and durability, wait 28 days before heavy vehicle use. You can walk on the surface after 24-48 hours depending on weather conditions. Rapid-setting concrete mixes can reduce waiting time to 3-5 days but cost 20-30% more. Premature trafficking causes surface damage, cracking, and reduced long-term durability. Keep surface moist during first 7 days for optimal curing.
Standard 32 MPa concrete is recommended for most residential and light commercial pavements. Light-duty residential driveways can use 25 MPa, but 32 MPa provides better long-term durability for minimal cost difference. Commercial parking lots and roads require 40 MPa for heavy traffic loads. Industrial applications with container trucks may need 50 MPa. Higher strength grades cost $5-15 more per cubic metre but significantly improve pavement longevity and crack resistance.
