How Bitumen Calculator Australia Works
Visual calculation flow
Length × Width Area (m²)
→ × Thickness Volume (m³)
→ × Density AS 2150 mix
→ Result Tonnes
Asphalt (tonnes) = L(m) × W(m) × T(mm÷1000) × Density(kg/m³) ÷ 1000 Step 1: Enter your project dimensions in meters. The calculator multiplies length × width to get the area in square meters (m²).
Step 2: Select thickness in millimeters. The calculator converts this to meters (divides by 1000) and multiplies by area to get volume in cubic meters (m³).
Step 3: Choose your AS 2150 mix type. Each mix has a different density (AC10: 2320, AC14: 2350, AC20: 2380, SMA: 2400 kg/m³).
Step 4: The calculator multiplies volume × density to get weight in kg, then divides by 1000 to convert to tonnes.
Asphalt Calculator Australia FAQs
What AS 2150 asphalt mix should I use for my driveway in Australia?
For residential driveways in Australia, AC14 (14mm aggregate) is the most commonly recommended mix. It provides excellent durability for light vehicle traffic. For higher traffic areas or commercial properties, consider AC20 for added strength.
How thick should asphalt be for Australian roads and driveways?
Australian standards recommend 25-40mm for residential driveways, 40-50mm for light commercial, and 50-75mm+ for heavy vehicle access. Always include proper compacted base material (typically 100-150mm of crushed rock) underneath.
What is the typical cost of asphalt per tonne in Australia?
As of 2024, asphalt in Australia typically costs $150-$250 AUD per tonne for standard mixes, with premium mixes like SMA costing more. Delivery costs vary by location. Major metro areas (Sydney, Melbourne, Brisbane) tend to have competitive pricing, while regional areas may cost more due to transport.
Can I apply asphalt in hot Australian summers?
Yes, but extra care is needed. Hot weather actually helps asphalt compaction, but the base temperature should not exceed 50°C. Early morning paving is recommended during extreme heat. Australian contractors typically avoid the hottest part of the day (11am-3pm) during summer months.
